Im old and have seen long term regular/daily drug use of all kinds. All damage the person. Some are faster than others, some work on the body first, some on the personality, some on the soul.
All provide a false reward and/or an escape from reality that ultimately leads to a very unhappy life for the user and anyone who cares for them. There is a high cost to the user
He didn't say illegal drugs did no damage - he said he's seen far more damage from the legal drug alcohol. Everything you've said applies to that drugs; should it be illegal?
and to the society.
Higher than the cost to society - in dollars, criminal enrichment, and violation of liberty - of the War On Drugs?
My point was that both and all do great damage; I was objecting to saying alcohol is more damaging than pot. it’s different in ways I suggested, but not more.
