I wouldn't... it seems like karma usually gets people if you try to steal bud from another peson.. you'll end up regretting it.. and that just perpetuates the idea that stoners will do anything to get their buzz. Just buy ganj from someone, or even better... ask them or have your gf ask them and maybe you call all smoke out and have a great time.

Also, if you/your gf steals from them, it's likely that they won't be asking her back, and I know that it would be good to have as many potential job prospects as possible.

Just my 2 cents.
