Each trip has four stages: absorption, onset, peak, and descent. Each level consists of a series of hallucinations. After ingesting a magic mushroom, the beginning may take a few minutes to hours. It is followed by the peak, the trip’s high point where everything you’ve heard or pictured a psychedelic trip to be like. The experience will mostly depend on how you and your fellow trippers feel. The last stage is the descent or comedown; it is the onset in reverse but otherwise comparable. For detailed information on the psilocybin trip, you can read here.
