Yes, it's safe(Hear me out) But 1: You sound like a pretentious armchair douchebag talking about things like you synthesized it yourself, grow up and stop thinking you're above me, maybe take some more LSD ye, kill that phat ego

and 2 Yes it's safe. It's as safe as you said there is no mental issues etc etc. But anecdotally, there are tons of people saying after their numerous LSD usage it has slowed certain parts of their functions down ok. Now you're NOT going to dissallow these people to have those opinions based on their own experience, but with how many people say it HAS affected their short term memory, their focus/concerntration. We can say that it should definitely be looked into MORE than the 30 or so years we've had to research it.
