Diphenhydramine is the active ingredient in Benadryl, as well as most no-name allergy pills, motion sickness pills, and sleep aids. When taking in high doses, Diphenhydramine causes hallucination and extreme paranoia in some cases. On a DPH trip, the user experiences realistic visual hallucinations they can often confuse for reality, along with occasional audial hallucinations. The trip lasts anywhere from 2 hours to a day, dependent on the dose taken. If you or someone you know plans on tripping on DPH, you'll need the following : A trip sitter. (VERY important. VERY.), a small room. (The tripper may become uncomfortable in a large room.), Calming/Mellow music in case of freakout, and last but definitely the most important, experience with hallucinogenic drugs. This is DEFINITELY not the drug to start your tripping career with. The high is comparable to a weed high at the first plateau (around 30 mins after dose until an hour and a half after dose). At the second plateau, from two hours after dose to three, the tripper will experience audio hallucinations, and the occasional movement in peripheral vision. At the third and final plateau, the tripper will experience extremely realistic hallucinations, to the point where they will act on them. For example : Tripper begins to hallucinate a party. Tripper may begin to dance, serve drinks, and eat, despite there being no party.
