She blogged about going out to some nightclubs/"speakeasy" in California. That was where the whole 'Italian and Mexican' thing came from, because she was getting hit on by guys. Whether or not she went when she was in L.A. I don't remember exactly, because again, I have not gone back and looked at her blog in a couple of months because it takes so long to load and find things (maybe I'm just clueless with Tumblr).
But she definitely would have been in some environments where she likely would have had the opportunity to get drugs, or might have been offered them. Hell, even on the street in downtown L.A. she could have been offered something like ecstasy, but I would think it would more likely have happened in some type of club, if she did ever procure any drugs.
