The FDA regulates foods, drugs, and cosmetics. Tobacco is none of these. So why ask the FDA boobocracy to regulate it? (They don't exactly do a stellar job with the food and drug stuff.)

Nicotine is a drug and a VERY potent pesticide.
In fact, nicotine sulfate is listed among the deadliest of poisons.

Nicotine is a psychoactive addictive drug. Open and shut case anytime the nannies want to push the issue.
