Seeking A Good Laser Flashlight

Wednesday, April 14th, 2010

With the advanced invention of the Laser, great strides have been taken in the medical profession. Surgical procedures have been developed that would not have been possible a few years ago. Eye surgery has been a great success and has saved many from blindness. This invention has now spread to all areas of everyday living, including the Laser flashlight.

The Laser Flashlight Stimulated Emission, invented by Albert Einstein, is the basis of the Laser. Over the years a large number of inventors worked on his theory until it is now part of almost every piece of technical equipment, including the computer. Every household has something that contains a Laser even though they may not be aware of it.

People in all occupations use this technique in their everyday work. When you get a speeding ticket, for example, it was probably because the police measured your speed with the Laser. Carpenters use it to measure levels, soldiers have it attached to their guns to line up targets and hunters use it to hunt game. There are very few occupations where it is not in use.

Laser pointers are very popular with people giving lectures or other demonstrations. The Laser flashlight has received various reviews, depending on the model used. Contrary to the regular large batteries, only three AAA batteries are required.

Tests held showed that this type of flashlight lasted much longer than an ordinary one. For people in a desperate situation, such as a flood or earthquake, where power is out for days having a flashlight that will last that long is essential for their well-being. It has been found that the batteries in a regular flashlight lose their power very quickly and if there are no replacements on hand, a dangerous situation can develop.

People desiring a flashlight of this type might be tempted to follow instructions, which appear at various places on the Internet, to change a regular flashlight to a Laser one. It would appear that it might be difficult for an ordinary person to attempt to make this change. The reviews on successfully accomplishing this task are varied.

Light Amplification by Stimulated Emission of Radiation is the regular name for LASER. For the ordinary man the terms used in this procedure are difficult to understand. Words such as parallel beams, polarization, monochromatic and others are not in their vocabulary. However, technicians and designers can understand them and as a result have developed some amazing things that everyone uses in their daily lives.

The flashlight has been in existence for many years. It has saved a number of lives when used in precarious situations. Things such as a stormy weather rescue, finding a person in the water or other such situation have made it one of the most valuable tools available. Now this instrument has been improved and updated to the present Laser Flashlight. As with any new, tested equipment, it has met the test and will no doubt, in time, be the only type of flashlight on the market.

laser flashlight sight I raced the short distance to my vehicle, and a giant porcupine rocketed from underneath. ~Ben Anton, 2007Cave hiking is considered to be an extreme sport in some circles. However, the initial price for LED bulbs would more than pay for itself in the long run.

Digital Cameras – An Evolution in Photography

Thursday, April 1st, 2010

Kodak developed the Photo CD system in 1990 and also proposed the first worldwide standard for defining color in the electronic digital environment of computers as well as computer peripherals. Kodak released the 1st professional digital cameras system (DCS) in 1991, aimed at photojournalists. It was a Nikon F-3 prepared by Kodak with a 1.3 mega pixel sensor.

The 1st digital camera for the consumer-level market that worked with a personal computer via a serial cable were the Apple QuickTake 100 (February 17 , 1994), the Kodak DC40 (March 28, 1995), the Casio QV-11 (with LCD monitor, late 1995), and Sony’s Cyber-Shot Digital Still (1996).

The marketing worked and today digital cameras are the world over. At present Pentax, Nikon, Canon, Olympus, Fuji, Panasonic are the top brands in the field of this industry. Additionally, there are about ten various kinds of the products like compact digital, bridge, SLRs and live scan to name few.

A digital camera saves pictures digitally by utilizing a memory card rather than saving them on film, making digital photography exciting. The greatest benefit of this product is that making photos is both economical and quick because there is no film processing.

Another huge benefit of digital over film is direct synchronization with the computer. Today’s the product can directly be linked to the computer system and can be printed and shared quickly. Traditional cameras rely entirely on chemical and mechanical processes. In digital product however, no chemical reaction is required to make the image. It is done electronically.

The digital camera not only shoots pictures, it also presents the added advantage of seeing your photographs now, the ability to experiment without worrying about expense, the technology to fine-tune your photos, and the means to share your work instantaneously with anyone, anyplace in the world. So have digital cameras, go and click away, and have fun with the ecstasy of photography.

The Short History Of E-Cigarettes – Increasing Use Or Attempts to Kill The Competition?

Monday, March 29th, 2010

Electronic cigarettes have a short history as they were introduced in 2003 by the SBT Co. Ltd. of Beijing, China. After the first launch, Ruyan developed the electronic products further and introduced electronic cigarettes to the European market at a 2006 Austrian conference. Marketing promotions assigned the name “Electro fag” to electronic cigarettes.

Initially, the e-cig was not meant as a replacement for tobacco but as an alternative nicotine delivery system to be used where tobacco smoking was not allowed. The purpose was simply to ease the nicotine cravings of smokers during periods when smoking was not an activity they could indulge in. Overly promotional marketers quickly began referring to e-cigarettes as a method to help the public stop smoking. Manufacturers recognized the danger of making such claims and disapproved of the ads. The World Health Organization issued a statement condemning the portrayal of electronic smoking products as a cure for smoking as benefits and risks of e-cigarettes had not been tested.

Some smokers think of their e-cigs as a hobby but not a habit. Online forums for “vapers” (those who use electronic cigs) heatedly discuss the merits of one brand over another, the strength of various e-liquids and argue about which e-cig provide the highest volume of vapor to the smoker.

Initial products attempted rather unsuccessfully to mimic the appearance of tobacco cigarettes. As the e-cig has become a product in its own right those designs have been joined by colored and brightly decorated models and with e-cigarettes displaying logos. The electronic products that do resemble standard smokes are much more realistic in detail than those early products on the market.

In 2009, electronic cigarette suppliers formed their own trade association with a goal of providing factual information about electronic cigarettes and correcting misinformation spread by others. The focus is to promote electronic smoking as an alternative to smoking tobacco.

A significant amount of opposition has been aimed at electronic cigarettes by tobacco and pharmaceutical companies and the powerful lobbies that represent them in Washington, D.C. Bowing under pressure from these large corporations, the FDA has issued statements against e-cigarettes and last year imposed a ban on imports of the product from China. Recent court decisions may help counter the FDA’s policies and limit the ability of the lobbies to influence decisions of a government agency.

Tobacco companies and pharmaceuticals have been quick to spread misinformation about the effects of e-smoking. Amazingly, companies that sell the most dangerous consumer product available to the public are expressing concern about the safety of electronic cigarettes and the effect e-cigs might have on public health.

The two piece disposable cartridge design is a recent innovation in the electronic cigarette market. After about 400 puffs, which is the equivalent of one pack of cigarettes, the smoker simply unscrews the spent mouthpiece and screws on a new cartridge pre-filled with nicotine solution. No cleaning is needed, no e-liquid is required and changing the cartridge is as easy as opening a cigarette pack.

Electronic cigarettes may have a short history but there is a huge potential market for these products. Demand continues to increase as more information about the safety and improved quality of the best electronic cigarettes becomes available to the smoking public.

Electronic Cigarette Association: Protecting Nicotine Users And E-cig Suppliers By Replacing Misinformation With Fact

Sunday, February 28th, 2010

The e-cigarette industry launched the Electronic Cigarette Association to provide a platform to speak for the producers, distributors and retailers of electronic cigarettes. The trade association was formed in 2009 in Washington, D.C. and is funded through donations and by the members. The ECA answers questions about e-cigs, provides accurate information and focuses on public relations.

The ECA provides a collective voice for both e-cigarette providers and organizations by publicizing accurate information and providing the tools necessary to opinion leaders, policy makers and the news media. By instituting a code of conduct that is industry wide, the ECA hopes to reassure the public and legislators about the safety and purpose of electronic cigarettes.

Powerful lobbyists of big tobacco and large pharmaceutical firms have attacked e-cigarettes from the time the products were introduced in 2003. Pressure from these highly financed lobbies resulted in the FDA conducting a very limited and unscientific study of e-cigs and issuing a caution about their use.. The Electronic Cigarette Association aims to combat the push to ban the products. Results of the FDA testing found a trace amount of a risky compound but did not compare that result with a similar test for the compound in tobacco products. The big corporations realized in 2003 that the electronic versions could damage their profits and they have been applying pressure for a ban since then.

The e-cig is presented as a safer and cheaper alternative to tobacco products in the information disseminated by the ECA. Users are encouraged to share their stories about tobacco and e-cigs and urged to contact legislators and argue against any ban of the product.

When new products are introduced, especially if they are innovative, misinformation is to be expected. For generations the health risks of smoking tobacco have been well documented and accepted. Smoking tobacco products was totally acceptable for generations and accomodations (and ashtrays) for smokers were available wherever you looked. The macho Marlboro man died of lung cancer. The feminist Virginia Slims lady is not seen as glamorous by women today.

The number of ingredients, additives and compounds in tobacco are now fully understood as are the serious health risks involved in smoking. Public buildings and places of entertainment such as restaurants, theaters, and even bars have banned smoking and the trend toward non smoking public areas is spreading to more public places.

For years the public asked for a safer alternative to smoking tobacco and that is exactly what is provided by electronic cigarettes. Big tobacco stands to lose a lot of money as the popularity of e-cigs continues to grow as they provide an alternate nicotine inhalation system that doesn’t expose the smoker to the additives and burning chemical compounds of tobacco. Pharmaceuticals also stand to lose profits. Unfortunately, these two sectors provide a lot of money to legislators.

The first warnings on cigarette packs appeared after the surgeon general declared tobacco as a health hazard forty years ago. The FDA has refused to intervene in regulating tobacco products or additive and has shown no interest in banning the use of tobacco. Electronic cigarettes have been available to the public for only a few years yet the FDA has repeatedly mentioned banning or regulating e-cigs. The Electronic Cigarette Association was created to publicize the truth about electronic cigarettes in the hope that e-cigs will remain available to the public as a safer alternative to tobacco products.

Are Safety Factors Of Electronic Cigarettes A Real Problem Or A Political Agenda?

Saturday, February 27th, 2010

Debate about the safety of electronic cigarettes has continued since the product was first sold. Much of the information tossed about is factually incorrect but that hasn’t stopped big tobacco and big pharma from spreading the rumors.

A trade associate was recently formed to represent the interests of electronic cigarette suppliers and to refute the misinformation about the safety of e-cigarettes. Tobacco companies have issued warnings about e-cigs with a clear intention of eliminating the competition. High dollar lobbyists pushed the tobacco and pharma agenda with pressure on the FDA until that government agency conducted a limited test that was scientifically invalid. Using the unproven conclusions of the testing, the FDA issued several statements about potential health problems that might be associated with e-cigs. The handpicked small sample of e-cigs tested by the FDA had shown trace amounts of a harmful chemical in some of the products tested.

The FDA did not conduct followup testing or test to see if the same chemical was present in tobacco product. Although the statements made by the FDA were not factually incorrect they were also not scientifically proven but were conclusions based on a flawed example.

E-cigarettes contain only twenty ingredients. When the buying public asks “are electronic cigarettes safe” it seems best to point out that tobacco cigarettes contain 599 ingredients that produce over 4000 chemical compounds and additives when burned. Although claims are made by tobacco companies that cigarette additives have been approved by the FDA that is not quite the true picture. Those food additives were tested for ingestion as a food product. They have not been tests for chemical compounds that are created when the additives are burned. The high heat of burning can change the chemical elements of some products.

Poor nicotine is guilty by association with tobacco. Tobacco smoke is thought to lower the immune system in some smokers leaving them open to more colds and infections. We know for a fact that smoking tobacco causes cancers of the mouth, throat and lungs and increases risk of heart disease in smokers. These health problems are directly attributed to the tars and noxious gases of burning cigarettes inhaled by the smoker.

The properties of nicotine itself to not promote cancer in healthy tissue and nicotine has no mutagenic properties when separated from tobacco. There is no evidence that long term use of nicotine is detrimental to health. Nicotine is the reason we become addicted to tobacco. It is the fix we want when we light a cigarette yet it is not nicotine that damages our health.

You can buy nicotine stop smoking patches and gums at your local Walmart. Initially, the patches were only available with a doctor’s prescription but years of wide usage with negligible side effects resulted in nicotine replacement products being freely available..

The best e-cigs deliver a measured dose of nicotine to the e-smoker. Nicotine is provided in a safe form that soothes the smoker’s craving without the risks of smoking tobacco. The Royal College of Physicians stated they do not suspect adverse health effects will result from the long term use of nicotine.

Revealing The Truth About Propylene Glycol And Electronic Cigarettes

Friday, February 26th, 2010

Warnings issued by big tobacco and big pharma about the dangers of propylene glycol are not grounded in scientific reality or backed by scientific research. After a study in mice at the University of Chicago’s Billings Hospital in 1942, it was thought that propylene glycol when inhaled might cause such diseases as pneumonia and other illnesses affecting the respiratory system. To determine long term effects followup studies on money and other animals were conducted. This larger study produced results that showed no ill effects from propylene glycol in the lungs.

In a newly discovered zeal to protect the health of hte public, tobacco companies and the FDA shout “danger” when discussing propylene glycol. It’s an interesting strategy as PG has been proven safe and accepted by the FDA for years. The warnings ignore the elephant in the room. E-cigarettes are safer than tobacco. Almost anything you inhale is safer than smoking tobacco.

Propylene glycol in e-cigarettes dilutes the nicotine in a solution that can be deliver to the smoker as a vapor. PG is commonly used as a food additive and is an ingredient in many products we buy. Propylene glycol is the substance that produces the fog generated by fog machines.

The warnings of the dangers of PG do not come from researchers, doctors or scientific journals. Online sites issuing warnings are full of anecdotal (and seemingly imaginary) stories and are blogs often devoted to conspiracy theories. Several comments contain the statement that “propylene glycol is antifreeze”. Well, no, it isn’t. That would be ethylene glycol. Natural healing sites and anti-smoking groups are also quick to talk about potential danger of the use of PG.

A fantastic amount of information can be found online but it’s important to know who you are listening when accepting information as fact. Baby wipes contain PG and it’s difficult to imagine the FDA making claims that a product freely allowed for use on infants is now unsafe for adults. The PG delivered to the user by the best electronic cigarettes is minimal. Some e-liquid suppliers use glycerol as a base for their nicotine solution rather than propylene glycol.

Consumers are more conscious of food additives and harmful ingredients in the foods they eat than every before. Looking at the ingredients on products you buy is a smart thing to do. We know to look carefully at labels when buying products low in sugar. Ingredients such as sucrose and fructose and various types of “syrup” may be listed and each of those ingredients is sugar.

Thirty years ago the FDA announced a ban on saccharin and any products containing saccharin. The public was in a panic and threw out their boxes of sweet and low while manufacturers hustled to change the recipes of their food products. Only later was the public told the truth.

The mice who contracted cancer from saccharin were given a daily dosage that when converted to human quantities would require a person to drink the equivalent of 400 cans of diet soda each day for months. Saccharin is freely available in stores today.

The delivery of vapor for e-cig users relies on the use of propylene glycol. The tobacco companies continue to spread false information about PG even though there is no scientific data to prove their claims

The FDA Attempt To Stop E-Cigarettes Is Blocked By The Federal Judge

Tuesday, February 23rd, 2010

The first statements about safety concerns of electronic cigarettes were issued by the FDA in a way that suggested a government agency bowing to pressure exerted by big tobacco. For the FDA to mention banning a product before testing had been conducted is not the way that government agency usually conducts its business.

For forty years the public has been informed about the dangers of smoking tobacco. That is when the first warnings were placed on cigarette packs yet our current pack warnings are among the weakest in the world. Only last year was the FDA sufficiently concerned about tobacco to move to regulate the products. In a magnanimous statement, big tobacco said they welcomed regulation and oversight by the FDA. Of course they did. It was a smart move by a company that could influence the regulations and make it more difficult for competing products to reach the public.

With hints indicating a wish to ban electronic cigarettes, the FDA issued statements about safety concerns. Last year, the FDA claimed it had concerns that young people would be lured into nicotine addiction by the e-liquid used in e-cigs. The FDA then issued a ban on importation of electronic cigarettes aimed at China which is the main source of imports of the products.

The ban ended up in federal court on January 15, 2010 where a federal judge ruled the FDA could not ban the importation of electronic cigarettes. The judge strongly criticized the federal agency for aggressive tactics that seemed aimed at designating a particular recreational product as a drug or device in an attempt to make the product unavailable to the public.

Pointing to the newly established tobacco division created within the FDA to regulate tobacco, the judge stated that the same regulations could be applied to electronic cigarettes and supplies.

The FDA quickly released a statement opposing the court’s view and expressing concerns over health issues that might be posed by e-cigarettes. Critics have pointed out the tendency of the FDA to change focus from dangers of youthful smoking to general health concerns when it suits the agency. If the FDA appeals the court decision it will have full backing of tobacco manufacturers who would love nothing more than to see new competition banned.

The costs of electronic cigarettes would increase greatly should the FDA be allow to set standards and restrictions on the products. Big tobacco currently cannot compete with the lower cost of e-cigarettes.

The court decision defined a need to scrutinize the relationships that exist between tobacco companies, pharmaceutical concerns and the FDA. Taxes from the sales of tobacco products put billions of dollars in federal and state government coffers annually. Many of the attempts to create fear of electronic smoking alternatives seem to be more concerned with the financial bottom line than with the protection of public health the FDA is charged with. Had big tobacco been the industry that introduced and promoted electronic cigarettes it is doubtful a controversy would exist.

Is the FDA truly concerned with protecting the health of the public? If so, why has the FDA never proposed banning tobacco? Why is the FDA pushing for bans on an entire line of products popular with consumers without conducting scientific testing to prove or disprove these imagined fears? It seems the justice system may require the FDA to answer those questions in the future.

E-Cigs Yield A Real Alternative To Those Suffering From COPD

Sunday, February 21st, 2010

Chronic Obstructive Pulmonary Disease (COPD) may occur when bronchitis and emphysema co-exist. Shortness of breath due to a narrowing of the airways is the primary symptom of COPD. This disease cannot be reversed and symptoms progress in severity over time. Those who suffer from asthma may display the same symptoms but the narrowed airways are reversible for those afflicted with asthma attacks.

Tobacco smoke is the primary cause of COPD. The diagnosis refers to the presence of two diseases present in the patient. Chronic bronchitis is caused by an inflammatory response in the larger airways of the body. Emphysema is damage to the tissues of the lungs caused by an inflammatory response that affecting alveoli of the lungs. The inflammation is triggered by noxious gases and particles inhaled by tobacco users.

Symptoms can worsen suddenly leading to acute episodes of COPD. Pollution in the air or an inflection can quickly lead to an acute episode. Lung function tests are used to diagnose COPD with testing to measure the volume of air and the speed of air flow of the patient.

Those who suffer from COPD require long term oxygen therapy. We’ve all noticed people in public who are carrying an oxygen pack or pulling a cart with an oxygen tank to help them breathe.

COPD is not curable but relies on management to delay the advance of the disease and to help avoid acute attacks. Management strategies outlined by doctors include advice to stop smoking tobacco and to participate in rehabilitation and drug therapy. Inhalers are the most common drug therapy prescribed for patients.

COPD is often found in highly addicted tobacco users. Some have given up trying to quit smoking in the belief they do not have the will power required to do so. Many continue to smoke in spite of a diagnosis of COPD claiming there is no need to quit as the damage has already been done. Tobacco smokers have a lot of reasons for not quitting,

To increase flow to through the airways, rehabilitation for COPD patients includes sessions where they breathe steam. For those who continue to smoke two or three packs of tobacco a day the benefits of rehabilitation are short lived. These are people who are addicted to the total experience of smoking. Whether taking a puff, holding a cigarette in the hand or inhaling the smoke, this is someone who will not be placated by patches and gum. Their habit is too ingrained to be replaced by anything that does not provide the experience of smoking. Electronic cigarettes may prove to be a valuable tool for those with COPD.

Highly addicted smokers suffering from COPD find e-cigarettes to be a real alternative for them. The lack of toxic smoke allows them to gain greater benefit from rehabilitation and steam therapy. E-cigs allow the smoker to inhale a vapor that tastes and feels like cigarette smoke without inhaling the harmful chemicals of burning tobacco. The popularity of e-cigs for this sector of society has grown rapidly. Patients report an increase in their quality of life and some even claim the steam vapor produce by e-cigarettes is helpful as a steam therapy. Until scientific studies are conducted, proof of advantages of the vapor are only anecdotal. it may be that simply stopping the inhalation of the additives in tobacco smoke is responsible for the improvement in patients.

The Basics Of How E-Cigs Work Is Illuminating, But Not Necessary To Benefit From E-Cigs

Friday, February 19th, 2010

Consumers are often surprised when they learn how the mechanism of ane-cigarette works. The word “electronic” may give the impression of a complex system that must learned before use. That is far from the truth.

No higher education is required and you don’t need to take a course before trying an e-cigarette. Product development is only successful when technology focuses on both aspects of product creation. The first aspect is the technical work done to create a totally unique product that fills a need or solves a problem. Equally important if you want to create a product that will sell is to make that product user friendly. The goal of every product developer is to launch a product that works exactly as it is supposed to and is easy and reliable for buyers to use.

The operation of the atomizer, battery and vapor produced are a simple process for those using electronic cigarettes. The products provide an excellent example of advanced design creating a simple system that fills a need for consumers.

An atomizer and a battery are the main components of any e-cigarette. Both a short and a long battery section is included in most starter kits along with a battery charger. You will need to charge a battery for 2-3 hours before using your new e-cig. After the initial charge you can have one battery on the charger and the second in use.

Assembling the e-cigarette is as simple as can be. There are no little plastic bags filled with parts to be connected. All you need to do is screw the atomizer to the charged battery and you can be ready to smoke.

The mouthpiece is another name for the atomizer. There is absorbent material in the mouthpiece that is saturated with e-liquid. In refillable models, you will drip e-liquid into the material when you need to refresh the nicotine content of your e-cig. Other models use a pre-filled cartridge that is replaced when needed. A heating element located in the atomizer is activated by the battery and produces vapor to be inhaled.

The batteries are most often rechargeable lithium ion and battery life is determined by size and type of the battery, frequency of use of the e-cig and the quality of the product. An LED light at the tip of the battery is a feature that has been a part of e-cigs since their early development. Meant to represent the fire of a lit cigarette the light is often red or orange. On newer models, users may often choose any color of LED they prefer.

The best electronic cigarettes produce vapor automatically. Air flow is created when the user draws on the mouthpiece. This is similar to taking a puff of a tobacco cigarette. The air flow activates a heating coil in the mouthpiece and the heat vaporizes nicotine contained in the e-liquid for the smoker to inhale. Older manual models had a button to push to activate the heating element but automatic e-cigs are most popular today. The way in which e-cigarettes operate may be similar to the experience of smoking tobacco. There is a huge difference, however, in inhaling a mist vapor that quickly dissipates and inhaling tobacco smoke laced with toxic chemicals.

Market Share Grows By Knowing What Electronic Cigarettes Are – Myths, Blatant Lies and Big Tobacco

Wednesday, February 17th, 2010

The reason e-cigs were developed is necessary to understanding what electronic cigarettes are. For decades smokers could indulge their habit in any setting without interference. The tolerance for cigarette smoking has undergone a drastic change in recent years.

Public venues have become smoke free areas and public entertainment venues are rapidly following suit. The realization that second hand smoke endangers those around them has led to smokers indulging their habit out of doors. It is not unusual to find a small group smokers huddled in the cold or heat just outside the entry to a business.

The solution to the growing public intolerance to smoking is the e-cigarette which was introduced in 2003. Flavor and nicotine is delivered to the user through a vapor that has no negative effect on those around you. The e-cig may physically resemble a ball point pen or a tobacco product such as a cigarette, pipe or cigar with many designed to look just like the tobacco version.

Electronic cigarettes are reusable. The best selling model is the automatic style although manually activated models are also available. Some e-cigs come with disposable components while others are refillable.

A sensor in the mouthpiece detects the flow of air when a user inhales with an automatic electronic cigarette. The heat element that is activated by the sensor changes the nicotine solution in the mouthpiece to a vapor. An LED light at the other end of the e-cig is also activated when you inhale. Earlier versions routine used a red or orange LED to simulate the burning end of a tobacco cigarette but newer varieties offer LED lights in many colors.

On the manual models the user must press a button to activate the heating element and release a vapor. Manual and automatic style use the same electronic circuits and rechargeable batteries in their delivery systems.

The tip of the mouthpiece may be round like a cigarette or shaped like the plastic mouthpiece of some cigars. Absorbable material in a small cup located in the mouthpiece is saturated by the user with an e-liquid that is a flavored product that contains nicotine. The common name for the mouthpiece is “cartridge” and it may be refillable with the e-liquid or may be a disposable cartridge that is simply replaced when the solution has been used. The heating element is the “atomizer” and located in the battery section of the e-cig. Heat is used to vaporize the e-solution allowing the user to inhale the vapor.

The purpose of e-cigs is to act as a delivery system for nicotine. The e-liquid can be purchased in many flavors and in various concentrations of nicotine. The concentrations resemble the nicotine levels in tobacco products with regular, light or ultra-light strengths. E-cigs provide an efficient delivery method for nicotine that does not affect those around you or spread foul odor inside your home. Understanding how the product works quickly answers the question “what are electronic cigarettes”.
