Of course, no one knows what he might have been like if he hadn't smoked marijuana. Maybe he could have been the next Bill Gates and employ 120,000 people?
Smoking pot might be like pugilistic dementia and boxing. Some boxers take a lot of blows to the head in their careers without brain damage but they are the exception rather than the rule.
or it could be that people react differently. Genetics, environment, dosage, and other factors.
For example only 25% of smokers get cancer. Yet we are so conditioned that if we even see a cig, we think we might get cancer.
Or if you see a gun, you will die.
I am not a proponent of smoking, drinking or drug usage by any means. I have tried mj once, my thinking skill were “clouded” for a week so didn’t do it again. I am thankful for hangovers so I don’t drink much. I am thankful for restrictions on alcohol in my youth or Dad would have lost the family farm.
These are not clear cut issues that get the same response in all cases. Some people have an addictive personality whether, drugs, porn, drinking, homosexuality, etc.
The issue is when does their freedom intersect with mine. Prohibition did not start overnight. It began in the much earlier when many people had personal experience with losing, family and fortunes to alcohol. It was real to a lot of people.
Freedom works when we are subject to Gods laws as our founders understood.
I am fairly certain that I read that Bill Gates was a pot smoker. He does still support its legalization.
