Used to belong to a Homebrewing forum (beer, not computer servers), and they had monthly post about someone wanting to infuse their beer with tobacco. Which is where I learned that it will kill ya dead. Tobacco can be used externally to reduce swelling, chew on a wasp sting will prevent a lot of it. Or if you're looking for trouble late in life I guess you could smoke it also, though that one seems a great deal less compelling to me.

Re-iterate - Don't eat any food made with tobacco, it will harm you at the very least.

One more idea of this kind and I'll boil your potato chips and a game console. Obviously you'll like them boiled no less than in standard variants.

Only once. Tobacco is highly poisonous. The tobacco from a cigarette butt kan kill a child.

I can't remember which episode it is, but there's an episode of one of Anthony Bourdain's shows where he visits a restaurant run by his friend.

This chef is serving a massive multi-course meal, something like 10+ courses, and knows that Bourdain is a heavy smoker. So at one point he brings out the next course and tells Bourdain something along the lines of "And this one is made with tobacco, so you won't try and get up in the middle of my dinner and go smoke".

I guess if the dose is low enough and the tobacco is mixed with the right foods, it could possibly make for an interesting flavour combination.

LOL this reminds me, my friend ran a web server in the early web days and decided that the smoking section at work was disgusting. So he started to take picture of it

much of the time the water in that thing was so disgusting... we joked about making meals with it

Not a good idea. Such a broth can be used as a pesticide but it's also dangerous to humans and animals. Nicotine also absorbs through the skin so, anyone trying this (which I can't recommend but for it's dangers and general lack of need for pesticides in home gardens) should be extremely careful and use all PPE (durable waterproof gloves, goggles, long sleeves, trousers, and waterproof footwear, as well as respirator if there's any chance of aerosolizing) when applying. Seriously. While it has been used historically by home gardeners, the toxicity is no joke.

And, always remember: Proper PPE is sexy.

Someone needs to try putting tobacco in a tea diffuser and report back

I'm trying not to imagine how awful that must smell.
