I have. I was never peer pressured!
I was very depressed and they made me feel happy and alive. I never drank alcohol though because it didn't give me any type of buzz it just made me feel worse.
I always knew the dangers, I think everyone does. I don't regret any of it. Part of It was the best years of my life but I don't condone it and I'm happy to have moved on with my life without "needing" the highs.
