Drugs, especially tobacco, were introduced to the public in the 17th century and became extremely popular in the 19th century.

Smoking tobacco started out as a fun and healthy activity for everyone as there was no research available for people to know how unhealthy it really was.

Cigarettes were common in society and large numbers of people used tobacco. People were smoking cigarettes everywhere: homes, universities, airplanes, restaurants, etc.

Later on, doctors found cigarettes to heighten the risk of lung cancer which is only one of many more side effects.

Due to this newfound knowledge, many people decided to quit smoking or look for alternatives, and children were encouraged not to smoke and taught of the health complications at a younger age.

However, in the last couple of years, a lot of teenagers and young adults have found themselves once again interested in smoking.

Because cigarettes have a strong smell, and current technology is very progressive, adolescents have found electronic cigarettes more attractive than real ones.

Nowadays, young people use the device almost everywhere as it does not have any smell, except the smell of the flavor one chooses. So far ,these e-cigarettes have been found to be healthier compared to real cigarettes.

The first idea for e-cigarettes appeared in the 1960s; but, the technology at that time was not capable of manufacturing the device. During those times high demand for E-cigs could not be met as there was no reason for people to stop smoking real cigarettes because nobody knew the consequences.

In 2007, E-cigarettes appeared on the American market for the first time. In 2008, the research showed that there were no toxic chemicals present in the devices and they were not harmful.

In the last two years, scientists started to pay more attention to the device as many people around the country were admitted to hospitals with symptoms of nausea, vomiting, or seizures.

The three ways one can possibly get poisoned from e-cigs are to swallow the liquid nicotine, absorb it through the skin, or inhale it (in form of liquid instead of vape). It also can be dangerous for people with heart problems, as it can clog arteries over time.

As the FDA and other health advocates became concerned and knew that it could become a widespread problem, much more detailed research developed.

Meanwhile, between 2011 and 2012 the number of teens owning and using E-cigs doubled. Currently, there are over 250 different E-cigarette brands on the market.

“When some of the many different kinds of products for the device were tested throughout last year, known carcinogens and toxic chemicals were found in the vapor as well as potentially toxic metal nanoparticles from the vaporizing mechanism,” reported the National Institute on Drug Abuse in 2013.

On the other hand, different scientists and doctors claim that even though E-cigarettes may be harmful, they still are safer than real cigarettes.

A professor at Boston University’s School of Public Health, Dr. Michael Siegel, said that the device is a good alternative for smokers as it doesn’t have tar in it, which is the worst part of smoking cigarettes.

Also, if the three things that can get you poisoned by an E-cig are avoided, then they stay harmless.

Electronic cigarettes are still very new to the marketplace, and it will take years to understand the true effect on the human body.

Therefore, it is extremely hard to make an intelligent conclusion about the long term complications.
