<human>: Can you summarize the given text in a few sentences?

I (m24) have a girlfriend (f24) who is kind of a hippie and we have been together for half a year. I was mostly straight edge in my youth. Now I drink on occasion and smoke with her from time to time. She is a more heavy user where she smokes maybe 2-3 times a day. I was wondering how this would effect her mind. I'm more so curious about the mushrooms and acid she does maybe once a month or every other month. She does other random drugs to at times but not as often. She stays away from really additive things like coke and such because she knows they are very harmful and addictive and that she has an addictive personality. She knows her limits and doesn't get fucked up every time she does it she like to still know what's going on around her. I was wondering if they brain can come back from all this if she ever tries to stop. Though I think she will continue to use into her older age. Just curious what I'm getting into really. (Short term lurker, first time post). Any stories, advice, or actual facts would be great to hear.
<bot>: I got a new hippie girl friend and she does natural drugs casually and safe dosages was curious if this is any better for the brain or is still harmful where you can't come back.
