Hallucinogens are psychoactive drugs that are classified into three main groups: Deliriants, Psychedelics, and Dissociatives. These psychoactive drugs are different from other drugs like opiates, and stimulants, which amplify familiar states of mind, whereas hallucinogens seem to bring out different states of mind and crazy mindfuck. Hallucinogens are used for religious purposes and have sculpted modern western civilization.
Deliriants are commonly known for their extremely realistic hallucinations and intense discomfort.
The effects of deliriants are auditory and visual hallucinations, best well described as voluntary schizophrenia. For example, people see insects, talk to people who don't exist, see objects morphing, shadows moving, have nonexistent conversations in the room next to them, experience confusion and forgetfulness, watch T.V. while it's shut off, among other effects. There are myths about the use of deliriants throughout the middle ages in Europe. There were many uses for deliriants during this time period including medicinal reasons. Most /dels/ are very deadly and can be fatal but if used correctly can have medical advantages.
The term 'Psychedelic' describes a wide variety of drugs, the most well known of which including cannabinoids, mescaline, psilocybin and LSD. Many psychedelics are members of the phenethylamine or tryptamine families. The word psychedelic comes from the Greek ψυχή δηλοῦν - literally 'mind manifesting'. This is the exact effect of the halucinations produced by psychedelics: the effects are very much open to manipulation by one's own mind, both conscious and unconscious. As such, the 'high' from psychedelics can range from euphoric, divine bliss to a waking nightmare. As psychiatrist Humphry Osmond famously wrote, "to fathom Hell or soar angelic, just take a pinch of psychedelic"
Psychedelics relate to most drugs but are most well known for their hallucinations and visual distortions. One of the most well known psychedelics LSD. Other traditional psychedelics include: Psilocybin mushrooms, DMT (Ayahuasca), Mescaline (peyote), Salvia Divinorum, Ibogaine, and LSA (morning glory and hawaiian baby woodrose seeds)
Research Chemicals with psychedelic effects include: 2c-b, 2c-b-FLY, 2c-c, 2c-d, 2c-e, 2c-h, 2c-i, 2c-p, 2c-t-2, 2c-t-4, 2c-t-7, 2c-t-21, 4-AcO-DET, 4-AcO-DiPT, 4-AcO-DMT, 4-HO-MIPT, 5-HO-DIPT, 5-MeO-AMT, 5-MeO-DALT, 5-MeO-DIPT, 5-MeO-MIPT, 5-MeO-DMT, aMT, Bromo-Dragonfly, DOB, DOC, DOI, DOM, DPT, MIPT
Psychedelics are usually safe to use and rarely have fatal effects, though several deaths have been confirmed world-wide as the result of overdoses on psychedelic research chemicals in recent years. Those with a genetic predisposition to mental illnesses such as schizophrenia are advised to stay away from psychedelics. Those on anti-depressants (particularly MAOI's, SSRI's and SNRI's) are advised to talk to check with their doctor (or /psy/, they USUALLY know their shit) before consuming psychedelics.
