Apparently marijuana was in the files. They were speaking how people who smoke marijuana are harder to manipulate because it makes us open our mind and question things more, whereas alcohol does the opposite effect. Which is why alcohol is promoted while marijuana is demonized.
Believing myself to be immune to manipulation is the only prerequisite to getting manipulated.
Is marijuana healthier and less addictive than alcohol? Absolutely. Is smoking healthy? Hell no! And you can still find yourself doing it every day out of habit. It’s just an easier habit to shake than alcohol or nicotine.
