Daniel Park, if your friends are currently smokers they would greatly benefit from using e-cigs instead. If they are NOT currently smokers there is very little chance that they will enjoy them very much.
E-cigs are meant to be used by smokers who either are unable or unwilling to quit smoking and due to their high expense in having to buy and replace all the components and because they require quit a bit of maintenance throughout the day, we find that non-smokers tire of them quite easily.
Here are some facts that I copied from the petition at the top of the page:
FACT: There is NO evidence of any harm or illness, due to electronic cigarettes, during the five years they have been on the world market.
FACT: Testing by the FDA and independent labs has shown that electronic cigarettes do not have toxic levels of chemicals and contain no more carcinogens than FDA-approved smoking cessation products.
FACT: Electronic cigarettes are advertised to and largely used by ADULT committed smokers, the majority of whom have no intention of quitting nicotine use in the near future.
FACT: There is no verifiable evidence to show that children/teens are attracted to electronic cigarettes.
FACT: Accusations that electronic cigarette advertising is targeting children is based entirely on the false assumption that adult smokers would not be attracted to candy flavors or electronic gadgets.
FACT: The overwhelming majority of electronic cigarette retailers already have implemented policies against sales to minors and anecdotal reports of minors purchasing electronic cigarettes are extremely rare.
FACT: Electronic cigarettes have been shown to be tens of thousands of times less toxic and less carcinogenic than traditional cigarettes.
FACT: The majority of electronic cigarettes users discontinue smoking traditional tobacco.
FACT: If electronic cigarettes are removed from the U.S. market, the majority of electronic cigarette owners will turn to ordering the devices from China or worse, return to smoking traditional cigarettes.
FACT: Electronic cigarettes pose little, if any, risk to the general public, yet their removal from the market would have a huge, negative impact on the hundreds of thousands of actual users of the devices.
