You’d better not use a vegetable in Tenessee – unless it has been approved as a medical device.
The state aims to ban anything which has got nicotine in it:
It is an offense to distribute or sell any product or device containing or delivering nicotine intended or expected for human consumption that is not a tobacco product, as defined in § 39-17-1503, unless such product or device has been approved by the United States food and drug administration for sale as a tobacco use cessation or harm reduction product or for other medical purposes and is being marketed and sold solely for that approved purpose.

The only problem being that many vegetables contain nicotine:
Using limited data on nicotine content of foodstuffs (tea, tomato, potato, green pepper, and eggplant) and the 198991 Continuing Survey of Food Intakes by Individuals (CSDII), the absorbed dose of nicotine is shown to be significant compared to present day environmental tobacco smoke (ETS) nicotine exposures.

This is going to really annoy vegetarians!
(I’d love to take the credit for spotting this, but in fact it was in Bill Godshall’s regular THR email update.)
