i want to know how much nicotine could be in the average plant (grown for about a year, maybe 7-8 months) at about 1% nicotine per gram dried plant material. (how much does a plant weight (all of the plant).

anythign else someone wants to say?

Nicotine is water soluble. A simple water extract can be performed, but there will probably be other things besides nicotine in it. If you don't mind that, then just boil down the tobacco till all you have left is residue. Don't do this with commercial additive-laden tobacco, though.

I would have to guess that, except for a pesticide, that there would be of little use for pure nicotine. Unless you're trying to kill a waterbuffalo with a rigged up paintball gun with a hypodermic needle rigged up to a cut down plastic dart.

Be careful, as only one drop of pure nicotine can killeth you. THC is much better. Looking to quit the cancer sticks, soon, myself.

Black Leaf 40, an environmentally safe and biodegradable agricultural insecticide used around the world, is 40 percent nicotine sulfate. Farmers have been using nicotine sulfate insecticide since the early 1800s. To make it, all you do is boil tobacco leaves in water with a little sulfuric acid (the same acid as in a car battery).

If you mix the resultant nicotine sulfate extract with a common alkali such as lime, then add a solvent such as ether, pure nicotine alkaloid - or free-base "crack” nicotine - will float to the top dissolved in the solvent
