Also, their VEEV vapes are only available in tobacco and menthol flavors, and those flavors have been shown to be less effective for tobacco cessation. (They also tried to push through laws banning other flavors, if I remember right.)

Check out the Pod Juice Freeze "Strawberry Kiwi Pomberry", for example. If not for the big nicotine warning on the bottom half of the label, I wouldn't be surprised if parents confused it with kids' Pedialyte, or some sort of DIY popsicle mix:
they try offering in tobacco flavors: "that's not effective for cessation!"
wtf are they supposed to sell then?!
Also, law enforcement could enforce existing laws against marketing tobacco to kids.
The most effective cessation flavor is supposedly "unflavored". I believe it's been banned (in the same way that strawberry lime pomegranate is "banned" -- not very effectively).
