This needs a more nuanced answer: Psychedelics are generally physically safe and anti-addictive, in the sense that you can't take more the next day and experience much of anything, and you generally have no desire to. However, they can be pretty psychologically brutal, especially at high doses, as they tend to heighten whatever you're currently feeling rather than necessarily make you feel good.
Acid in particular has a few other potential problems. One, it's active in micrograms, so it's hard to accurately dose. Two, dealers sometimes sell NBOMe as acid, which can kill you; a man got charged with murder when he and his wife took what they thought was acid and she died. Three, acid trips last a particularly long time, so if you're having a bad time, it compounds the misery. Four, it can cause hallucinogen persistent perception disorder, which are visual distortions that happen once the trip ends, sporadically happen, and may never go away. (From what I can tell, frequent trips at high doses tend to cause this, especially mixed with marijuana.) And five, probably as a result of these, people who take acid are slightly more likely to kill themselves compared to people who take no psychedelics. Conversely, people who take psilocybin mushrooms are less likely to kill themselves.
These are the things I wish that DARE taught me in school. I now consider psychedelics a hard drug, even though they're safer than drugs like marijuana, alcohol, and MDMA, and I don't recommend people take them unless they read a lot into them and take the necessary preparations.
Yeah, but posting yourself consuming illegal drugs can bring negative marks against you when searching for jobs. If you decide to party, don't post it to social media with your face and real name.
