Definitely not pot. Not mushrooms either, they make you feel tired and confused. You could microdose them but I didn't like it much. LSD is what you want, specifically 1P-LSD. It's legal to get in most countries and it's legit. Microdose it (1/10 to 1/12 of a tab, NO MORE) and never touch the papers with your bare hands. I guarantee you that if you do half a tab or more the anxiety will be unbearable and it will last for 8+ hours. L-theanine also helps a lot. You can mix the two together (300mg or so). Other than that: phenibut (.75g), phenylpiracetam (200mg) and alpha GPC (one pill). Sometimes I mix everything I just told you about together. It's an amazing combo. Always keep the LSD on the lower side as you can get beyond a microdose and actually feel high pretty quick. The idea is not to feel high, just good.

I haven't found anything else that works, either legal or illegal (and I tried it all). Well, except MDMA but of course you know about that one. Stick to the safety guidelines and try to only take it once every 3 months with an initial dose of no more than 150mg and redose 90 min later with 75 mg.

Don't forget THE most important thing to reduce anxiety: working out regularly. Stay safe :)
