How Long Do the Effects of Psychedelic Mushrooms Last?

Psychedelic mushrooms can cause severe anxiety and frightening hallucinations, which can last for quite a long time.

Psychedelic mushrooms, the main psychedelic ingredient of which is psilocybin, can create effects that last for a considerably long time. Compared to other drugs, even other psychedelics, the effects of mushrooms can be particularly enduring, something many drug users do not realize until they have already ingested the drug.

What are the Effects of Psychedelic Mushrooms?

The effects of these particular mushrooms can depend upon many different factors, including “the age, type, and dosage amount of mushroom used, the setting the mushroom is used in, the user’s expectations, past drug experiences and personality” (Center for Substance Abuse Research). Not only can these factors affect how the individual will experience the high caused by the drug, but they can also affect the length of time a person will experience them.

The common effects experienced by those who use psychedelic mushrooms include:

  • Nausea, vomiting, and cramping
  • Diarrhea
  • Yawning, drowsiness, and coordination problems
  • Numbness of the tongue, lips, and mouth
  • Muscle relaxation
  • Increased heart rate and body temperature
  • Impaired judgment
  • Heightened sensory experiences
  • Hallucinations
  • Synesthesia
  • Past experiences melding with present
  • Feelings of religious or spiritual experiences
  • Bad trips causing anxiety, panic, terror, frightening hallucinations, depression, and confusion

How Long Do These Effects Last?


Psychedelic mushrooms can cause hallucinations.

According to the National Institute on Drug Abuse, in general, “the effects of psilocybin, which appear within 20 minutes of ingestion, last approximately 6 hours.” However, according to CESAR, they can sometimes last as little as 3 hours or take as long as 2 hours to fully develop. The wild unpredictability of these drugs and the timing of their effects makes it very difficult to gauge what an experience with mushrooms will be like from one individual to another. Even a person who has already abused psychedelic mushrooms before will not be able to determine for certain if their next experience will be the same as their previous one.

How Do I Alter the Effects of the Drug?

There is no way to alter the amount of time the effects will last or the effects themselves for certain. You can attempt to minimize the length of time you will experience them by taking smaller doses of the drug, and you can try to reduce the risk of having a bad trip by avoiding the substance when you are “upset, feeling low or insecure” or by taking the drug only when you are with someone you know and trust (Brown University).

Unfortunately, though, there is no surefire way of knowing what effects you will encounter or if they will last less or more than the full six hours that are most often experienced by users. If your experience has become dangerous or frightening, it is important to “seek medical help right away.” It is always better to be safe, and the effects of psychedelic mushrooms, due to their unpredictability and their endurance, can sometimes be very harmful.
