Big Sombrero,
I'm with Bill on this one: I don't think that saying that I did drugs and, in the words of Bill Hicks, "had a reaaaaalllll good time," is romanticising drug use. I think your just telling the truth about your experience, and now that your sober, you are just
choosing not to do them anymore because of the consequences.
That's my personal belief.
Bill Hicks - Positive Drug Story - YouTube
and
Bill Hicks - Drugs and Evolution - YouTube
All of this material was done after he was sober, which he remained til he died. So, I don't think that saying or admitting or talking about having positive experiences on drugs necessarily threatens or invalidates your sobriety. But, having never been a hard-core addict, what do I know?
Cheers!
