yeah your friends must be getting their weed somewhere, so just ask for their dealer's number or location and do it yourself. Just make sure not to get ripped off - never pay more than $50 for 3.5 grams (an eighth.) I used to mooch off my best friend, but she got sick of me taking all her weed (understandably) so now we split an eighth from her dealer. Just offer to split some of the cost of the weed with your friends next time they go out and buy some.
