Dude, Proof, seriously, 2 grams in a blunt is fine, thats over half an 8th. Depending on how many people you have smoking, 2 grams should do for a nice 6 man blunt. 4 gram blunts are a waste unless you have 10 or more people smoking the one blunt. Now, granted the qp is schawg, a 2 gram blunt would get at least 3 people high, maybe 4.
