now that i think about it ive been smoking a few times everyday for the past 2 years so i think 4 or 5 pounds is even enough. lets see half an eighth to a full eighth(about 2 grams usually) a day for 730 days equals 1460 grams more or less(probably more) and thats not even counting the 4 years before that. its kind of mindblowing to think about hahaha
