I mean, I like drugs music- see our previous discussion about Alien Sex Fiend, but I don't buy into the whole getting high will bring about revolution or change mentality. It's a plant, it's a piece of paper soaked in funny chemicals. Drugs are a nice diversion, and sure, drugs can provide insight to parts of a person they weren't consciously aware of, but I digress. I think as far as music that is significant to me within my ability to relate, that most of the hippie movement was just not something that I can appreciate as a non participant. I can look at the era, and romanticize it a little, because coming off of the bleakness of WWII, and the all around conformity of the 1950s, I imagine it had to be emotionally liberating for the participants to buck convention and express art, emotion, and love, combined with the sensations gained by widespread and easily obtainable drugs. I had my phase of it, just filtered through a post-punk-goth sort of scene that was relevant to me at the time. I couldn't imagine snorting speed off of a Skinny Puppy cassette case, or dropping acid at sunset and wandering around til dawn anymore, but I'm glad for my experience then.
My mom assumed I was taking drugs from a really early age too from the music I listened to because it was so foreign sounding to her and my appearance changed, but thankfully she's also really naive, so I'd tell her "Well Mom, I actually smoked a bunch of pot earlier, and I'm tripping balls on acid RIGHT NOW." and she thought I was being sarcastic, when often, I was telling her the truth. She about shit herself when I told her this a few years ago.
