I belive it. The nicotine in one small PINCH of Cope is enough to KILL me. or at least thats how it felt when I tried it.
Yes, you can extract almost anything with some good lab apparatus, and some know how. Pure caffeine is strong. of course too much can kill. I remember trying a few No-Doz when I was in my last year of HS (those days I would try almost anything)... I didn't sleep for at least two days. That is nasty strong stuff.Or so they tell me. After high school, my friends at Georgia Tech extracted everything in the chem lab. They even made powdered caffeine from a couple of pounds of coffee. Good god that stuff was nasty strong!
