LSD is one of the most potent drugs you can buy. If you really wanting mindfuck hallucinations, try Salvia. it only lasts like 10-ish minutes and the effects go away after an hour.
LSD can potentially give you permanent effects, flashbacks, and all that, as well as causing other health issues. Flashbacks would be absolutely terrible. It can impair judgement, etc.
If you're actually intent on doing drugs, at least go for a MUCH, MUCH weaker one, especially if you've never done acid before.
