LSD, also known as acid, is a potent psychedelic drug derived from ergot fungus, causing long-lasting and unpredictable mental and physical effects. Its physical side effects include pupil dilation and increased heart rate, while psychological effects can range from euphoria to paranoia and hallucinations. Long-term use can lead to tolerance, potential toxicity, and psychological challenges such as flashbacks and increased susceptibility to mental health issues.

4. LSD – Effects and facts
Even though the effects of LSD are more pronounced on a mental
rather than physical level, some consequences linger following long
term use of the drug. First of all, individuals can develop tolerance for
the drug, and then require a larger dose of LSD for the desired effects.
If the dose is too high, this can lead to a life threatening level of
toxicity. A cardiovascular collapse or sudden heart failure is also a high
possibility following a long term use of the drug.
Mixing LSD with other drugs poses a serious health risk and can also
drastically increase the chances of a bad trip. Mixed with alcohol, LSD
can cause nausea and vomiting.
