What happens if you use LSD often?

The risks of using LSD long term are mostly psychological, not physical. Tolerance to LSD develops quickly, meaning that the more often you use it, the more you have to take to feel the same effects. As LSD can be described as an intense experience, most users only take it from time to time, and it is not a drug that people commonly become addicted to. LSD does not often cause overdoses but can lead to emotional and mental changes in perspective that can be upsetting or unsettling for some people, even long after the trip wears off.

One of the main longer-term impacts from using LSD is having ‘acid flashbacks’. The proper term for this experience is hallucinogen persisting perception disorder (HPPD) and is unique to psychedelic drugs like LSD. After using LSD, you may find that you have times where your perception and senses suddenly become distorted. This might be what you see, feel, hear or taste. You may have visual hallucinations, see halos of light around objects or see flashes of colour. These can last anywhere from a few seconds to several days (or longer in some severe cases). The research isn’t clear on how or why these happen or how common it is to experience HPPD, but it is considered relatively rare. HPPD can be managed with some medicines and with psychological support.
