I never did, either.
Many of the people I knew in the ‘70s did, but they don’t now. The ones who are still alive, grew up.
It is too bad more people didn’t follow Nancy Reagan’s advice and just say “no” to dope. For me it was never a temptation and I never tried it. It smells nasty and the main symptom of users is that they care less and less about the important things in life. The best advice is keep your mind clear and sharp and avoid substances that could cloud it.
