Vapes, e-cigarettes and mods are all terms for electronic smoking devices that allow a person to inhale levels of nicotine the user chooses with an assortment of flavors.  This is now a three billion dollar industry worldwide, 2.5 billion in the United States alone.  Though you may already know about it, considering a new study shows that 79.7% of adults are aware of e-cigarettes. This may be considered as a total noob when compared to the conventional cigarettes.

The number of e-cigarette users has increase since the past. Although the use of electronic cigarettes is not widespread, it is neither negligible. Almost one out of every 10 smokers has at least tried an e-cigarette once. However, today there are several regulations around e-cigarettes, vapes, and mods.

How did this happen?

In 2009 the FDA tried to ban vaping, considering it a dangerous drug, even going so far as stopping the entry of vapes into the country at the border.  A 2010 legal decision by an appulate court declared that vaping was not an illegal drug and that the FDA couldn’t seize vapes.  But, the court suggested that if the FDA did want to regulate e-cigarettes then they would have to treat it just like any other tobacco product.  Which is what the FDA is in the process of doing.
