600 times more nicotine in mj than tobacco....but nicotine can only be studied as a gas, so it's really hard to tell...that number could have come from a thousand different places...and i could be a different number, and it varies on who grows it and how it's grown and all that....I really didn't know all that about the polonium though....that's really news to me....if anything makes you wanna fucking quit smoking, that does...thanks guys, that's my learn for the day...
