What is LSD?


LSD is a psychedelic drug.

People take it for varying reasons: personal growth, spiritual growth, to have fun alone, to have fun with friends, or just to experience altered states of consciousness.

Impaired judgement leading to doing something dangerous or deadly. Best mitigated with a safe environment and a trusted and experienced sitter.

What are good things about LSD?

Positive effects during use:

  • Joy/intense happiness4
  • Peace/harmony4

Desirable effects after use

These effects were primarily reported at the 6-9 month follow-up of a non placebo-controlled study of a high-dose guided session of LSD (150-400 micrograms).5

These positive effects will not all apply with casual use. These benefits were found for participants that followed a particular guided acid trip protocol, as detailed in the Psychedelic Explorer’s Guide.

  • More energy for work (p .01), more initiative (p .01), finding the job easier (p .01), and getting more work done (p .01)5
  • Increased cooperation (p .01)5
  • Increased confidence in one’s decisions (p .01)5
  • Being closer to others (p .01), having more friends at work (p .01) and outside work (p .01)5
  • Increased self-confidence (p .01)5
  • Increased marriage satisfaction (p .01)5
  • More satisfaction with intercourse (p .01)5

Does LSD have any medical uses?

“For example, a recent meta-analysis of six randomized clinical trials of treatment for alcoholism conducted between 1966–1970 found that a single dose of LSD [acid] reduced the probability of alcohol misuse almost two-fold relative to comparison conditions (Krebs and Johansen, 2012).”8 6
