Hi Conan,
Well you do sound like a good guy, and I'm glad we could clear the air.
Your views about drugs seem pretty balanced. I think it's good to try everything once (or twice
) A person can be healthy and take drugs.
Whatever damage is done can be repaired in most cases, as the body has a wonderful ability to regenerate and heal itself every day infact, new cells form and replace old ones.
Yes, some braincells are lost forever...but there are trillions more to work with, and we have barely scratched the surface of the potential within our brains. Drugs can help with that to a degree...but you need to know your limits, as with anything in life. But it's not for everyone.
It's good to enjoy life and explore. It makes for a well rounded individual.
