The phrase "burnt out hippie" exists for a good reason. I was widely regarded as brilliant when I started smoking. After 30 years of smoking almost every day, and about 5 years of smoking a few times a year, I'm noticeably dumber than peers who didn't smoke, who I used to run circles around. With very few exceptions, I've only used weed. For me, the biggest harm was brain damage.
