For those that say extracting nicotine at home is easy, please explain.
From listening to the chemists on this forum it is not "easy" to get any reasonable amount of nicotine.
Well, the problem isn't actually extracting the nicotine, the problem is doing it with nontoxic ingredients that don't corrode the equipment used. Heck, you can extract nicotine from tobacco with ammonia, but you end up with other ingredients beside the nicotine. You could make a simple tincture with snus packets, vg, and a crock pot.
You shouldn't ever have to worry about that though. Nicotine has many uses aside from vaping and cigarettes. A nationwide ban of Nicotine seems extremely unrealistic.
