How the kcuf is flavored tobacco illegal but flavored alcohol is not? There are no fewer than 20 flavored single and double shot, flavored liquor bottles on the counter of my local. Then we have the moonshine with actual fruit in it. Marshmallows and pickles, too!
The people who are responsible for kids using flavored e-cigs are the people who give/sell the e-cigs to the kids. Your average 16 year old is not going to be able to walk into a store and buy on, without a corrupt store owner, any more than one can pick up a pack of Marlboro. Yes, there are corrupt store owners.
With the recent upturn in pot laws, maybe law makers can get their heads in the same place and figure all this shit out at once.
