How Long Does LSD Last?

The effects of LSD (lysergic acid diethylamide) typically last 8 to 12 hours, although the exact duration varies depending on factors such as the dose, the individual's physiology, and the setting. While the main effects usually wear off within half a day, some people report feeling mentally or physically tired for the rest of the day.

A general timeline is:

Onset: Usually begins within 30 to 90 minutes.
Peak effects: Commonly occur around 2 to 5 hours after onset.
Main effects: Typically continue for 8 to 12 hours.
After-effects: Mild changes in mood, alertness, or fatigue may linger for several additional hours.
