Aardvark

Apparently: "LSD or ‘acid’ has very random, and sometimes very frightening, effects. Trips feed off a person's imagination.

If panic sets in, the experience can be scary and confusing. Bad trips can be terrifying.

There's no evidence to suggest LSD does any long-term damage to the body or long-term psychological damage.

Avoid taking acid if you're in a bad mood. People have been known to harm themselves during a bad trip.

LSD could have serious, longer term implications for somebody who had a history of mental problems and may also be responsible for triggering a mental health problem that had previously gone undetected"
