The Electronic Cigarette Forum, the main forum for electronic cigarette users, has published a guide for anyone wanting to buy an e-cigarette on their own.
The guide comes after the U.S. Food and Drug Administration banned the sale of e-cigarettes to minors last month.
The Federal Trade Commission (FTC) issued a similar warning in September, citing concerns about the marketing of e vices.
The Electronic Cigarettes Forum has also posted a “Get Out of Jail Free” bumper sticker for anyone looking to purchase an e cig.
It comes after several other prominent electronic cigarette companies have been slapped with anti-trust lawsuits in recent months.
A number of other popular electronic cigarette brands have also come under scrutiny for alleged price gouging and deceptive marketing practices.
