It really is dependent on the person.
I figured out at some point during the last decade that the only stimulant that works for me is THC. Caffeine won't do it. It doesn't matter what I do, if I eat healthy get 8 hours of sleep, exercise, etc, I can wake up and within 30 minutes of work feel so mentally and physically wiped that I have to sleep...rinse and repeat. I've managed to force myself to get through that repeatedly (it didn't really happen to the same extent as a kid - I guess life was more fun).
But weed? Scared the hell out of me the first few times (over years, I'm in an illegal state, but of course it's as easy to get as donuts). You know the usual introspection, whoa dude thoughts, the slightly different perspective you see yourself and the world, and on the high, every time...incredible anxiety. But once I got past that, I could work for 8 hours like I used to, and like most people can.
I was high 24/7 for about 4 or 5 years. I care about my health so I took different precautions (dealers, vapes, etc). However, I don't begin to smoke like some people (I'm not into pot culture), can't physically take those amounts.
Changed my life. I was able to work through major issues like OCD, etc. Guess what? Nobody at work or school nor my family or friends that I've only told recently know that I was high. Couldn't tell at all, entirely functional (more functional than the past).
The real save lately has been delta-8 (the way of the future). It (THC, drugs) is not for everyone and you should not abuse it too young (psychosis). Don't go buy weed off the street and get really high your first time, you might have the worst panic attack in your life.
I agree we shouldn't just rave about drugs like they don't have an impact, but some of you guys don't obviously have that much experience with what you are talking about (not you). No offense, but that's part of the issue. How many decades have we lost and how many tens of thousands of lives have been lost because we are too prudish to test this stuff as it should be?
The geniuses in my state, instead of grabbing the new industry were ready to ban delta-8 to protect the non-existent cannabis industry, or god, or something. It'll all be legal in 10 years anyway, why waste our time? I can't tell you how many small businesses I've visited in the last few months that would have out of business, and how many customers that might have been put in really bad mental spots.
There's a Cowboys player, Randy Gregory, that's lost 4 or 5 years of his career to bans because he smokes pot because it helps his anxiety and bipolar issues. That's criminal.
I drink, sometimes, too.
edit:
To save the Google, delta-8 is just a different form of THC, extracted from hemp produce federally legally due to the 2018 farm bill (magic). Of course there's also CBD from that (the original big industry) and lots of other things coming out Delta-10, etc.
Most people don't get extreme anxiety on THC, but some do... someone is going to correct me if I'm wrong, but THC is psychoactive (CBD is not), so when people are microdosing this or shrooms or whatever they're getting different effects but similar end results. It plays with your perspective and chemistry in a way that alcohol does not, especially at higher doses.
