A smart person can get a 3.7 in high school just for showing up. Do you really want to brag about being smarter than most people on a subreddit primarily devoted to drugs? Surround yourself with people that challenge you, that are "better" than you, that inspire you. If you're the smartest person in the room, you're in the wrong room, etc. If you're really that smart, then it'd be such a waste of your potential to use drugs before age 25+. If you really are this smart, then I'd imagine that you'd want to live your life and die knowing that you advanced and developed your brain as much as you possibly could - not just as much as your more average peers.
