List of hallucinogens
This is a list of hallucinogens, or psychoactive drugs that produce majorly altered states of consciousness.[1]
Psychedelics
[edit]Psychedelics, also known as serotonergic psychedelics or classical hallucinogens, are serotonin 5-HT2A receptor agonists and include the following:
- Tryptamines such as psilocybin, psilocin, dimethyltryptamine (DMT), 5-MeO-DMT, bufotenin, and α-methyltryptamine (AMT)
- Phenethylamines such as mescaline, DOM, 2C-B, 25I-NBOMe, and MDA
- Lysergamides such as LSD, ergine (LSA), ALD-52 (1A-LSD), ETH-LAD, and LSZ
- Others such as efavirenz, glaucine (possibly), IHCH-7113, mefloquine (possibly), MK-212, quipazine, and RH-34
Dissociatives
[edit]Dissociatives, also known as dissociative hallucinogens or dissociative anesthetics, are NMDA receptor antagonists and include the following:[2]
- Arylcyclohexylamines such as ketamine (K), phencyclidine (PCP), methoxetamine (MXE), and tiletamine
- Morphinans such as dextromethorphan (DXM), its active metabolite dextrorphan (DXO), and dextrallorphan (DXA)
- Adamantanes such as amantadine and memantine
- Diarylethylamines such as diphenidine, ephenidine, fluorolintane, and methoxphenidine
- Inhalants such as nitrous oxide (N2O) and xenon
- Others such as alkyl nitrites (poppers), aptiganel, dexoxadrol, dizocilpine (MK-801 or MK801), etoxadrol, and selfotel
Deliriants
[edit]Deliriants are muscarinic acetylcholine receptor antagonists, also known as antimuscarinics or anticholinergics, and include the following:[3][4]
- Tropanes such as atropine, scopolamine (hyoscine), and hyoscyamine
- Others such as benztropine, biperidin, dimenhydrinate, diphenhydramine, procyclidine, trihexyphenidyl, and tropicamide
κ-Opioid receptor agonists
[edit]κ-Opioid receptor agonists with hallucinogenic effects include the following:
- Salvinoids like salvinorin A (found in Salvia divinorum), 2-MMSB, 2-EMSB, and RB-64 (22-thiocyanatosalvinorin A) (possibly)
- Benzomorphans such as pentazocine, phenazocine, and alazocine
- Morphinans such as levorphanol, levomethorphan, and nalorphine
- Others such as spiradoline, enadoline, and HZ-2
GABAergics
[edit]GABAA receptor agonists
[edit]GABAA receptor agonists with hallucinogenic effects include the following:
- Muscimol, one active constituent of Amanita muscaria mushrooms
- Gaboxadol (THIP), a synthetic analogue of muscimol
Indirect GABAA receptor agonists
[edit]GABAA receptor positive allosteric modulators
[edit]- Nonbenzodiazepines or Z drugs such as eszopiclone, zaleplon, zolpidem, and zopiclone
GABA reuptake inhibitors
[edit]- CI-966, a potent GABA transporter 1 (GAT-1) blocker
Oneirogens
[edit]Oneirogens, also known as oneirophrenics, have an unknown mechanism of action and include the following:
- β-Carbolines and harmala alkaloids such as harmine, harmaline, tetrahydroharmine (THH), 6-methoxyharmalan, and 6-MeO-THH
- Iboga alkaloids such as ibogaine and noribogaine
Cannabinoids
[edit]Cannabinoids with hallucinogenic effects are cannabinoid CB1 receptor agonists and include the following:[5][6][7][8][9]
- Phytocannabinoids such as Δ9-tetrahydrocannabinol (Δ9-THC or simply THC)
- Synthetic cannabinoids such as nabilone, JWH-018, JWH-073, and HU-210
Certain monoacylglycerol lipase (MAGL) inhibitors, which inhibit endocannabinoid metabolism and hence are indirect cannabinoid CB1 receptor agonists, also produce partial or full cannabinoid-like discriminative stimulus effects in animal drug discrimination tests.[10] Conversely, fatty acid amide hydrolase (FAAH) inhibitors, which inhibit endocannabinoid inactivation as well, do not substitute for cannabinoids, at least by themselves.[10]
Other hallucinogens
[edit]Other hallucinogens that are not known to fall into any of the above groups include the following:
- Aminochromes such as adrenochrome and adrenolutin (disputed/controversial)[11][12][13][14]
- Carbogen, a mixture of carbon dioxide and oxygen gas[15][16]
- Glaucine, an aporphine alkaloid known to act on serotonin 5-HT2 receptors among other actions[17][18][19][20]
- Hallucinogenic bolete mushrooms such as Lanmaoa asiatica (unknown mechanism of action)[21][22]
- Hallucinogenic fish, which are reported to cause ichthyoallyeinotoxism[23][24][25]
- Icelandic hallucinogenic lichen ("rock soup")[26][27]
- Kambo (sapo), the skin secretions of Phyllomedusa bicolor (giant leaf frog)[24][28][29][30]
- Kykeon, an ancient drink of the Eleusinian Mysteries of unknown identity with possible hallucinogenic effects (disputed/controversial)[31][32][33]
- Mad honey (Rhododendron; grayanotoxins), a honey with hallucinogenic effects and substantial toxicity[34][35][36][37][38]
- Nutmeg, which contains active constituents such as myristicin and elemicin (unknown mechanism of action)[39][40]
- Sinicuichi (Heimia salicifolia), with possible active constituent of cryogenine (unknown mechanism of action)[41][42]
- Soma (haoma), an ancient drink made from a plant of unknown identity with possible hallucinogenic effects[43][44][45]
- Hallucinogen combinations (e.g., ayahuasca, teotlaqualli)[46]
- Others (e.g., less-well-characterized plant hallucinogens, insect hallucinogens)[42][24][23][47][48]

"Also there had been interest in reports that adrenalin that had become old and discolored seemed to elicit central effects in man. The oxidation products were identified as the deeply colored indolic compound adrenochrome and the colorless analogue adrenolutin. The controversy that these reports created just sort of died away, and the adrenochrome family has never been accepted as being psychedelic. No one in the scientific community today is looking in and about the area, and at present this is considered as an interesting historical footnote. But, in any case, they are not phenethylamines and so not part of this book."

There are a number of substances that may be called psychedelic, but are not "classical psychedelics." Among these are methylenedioxymethamphetamine (MDMA), Salvia divinorum and salvinorin A, the Amanita muscaria mushroom, tropane alkaloids and the plants from which they come, Cannabis and delta‐9‐tetrahydrocannabinol, ketamine, nitrous oxide, and carbogen. Although these substances also have "mind‐ manifesting" characteristics, the experiences they produce are qualitatively different from those of the classical psychedelics, and their known interactions with the nervous system also differ from 5HT2A receptor agonism. [...] Inhalation of carbogen, another gas, can induce profound alterations of consciousness that may possess psychedelic qualities (James & Erowid 2007). The psychoactive component of carbogen is simply carbon dioxide, mixed with enough oxygen to not be a suffocation risk. 30% CO2 and 70% O2 is a standard combination (Meduna 1950). Effects on cerebral blood flow and on blood pH are likely factors in carbogen‐induced altered states of consciousness. Similar mechanisms may be at work in the induction of powerful altered states via hyperventilation, a process that has been explored for millennia, from ancient practices in pranayama yoga to contemporary breath‐work therapies (Grof & Grof 2010).

"It was the most intense hallucinogenic experience that I've ever had, and I've done every trip there is," says Icelandic writer Smari Einarsson... It is actually the lichen that lives on the rocks that gets you off. You take a few stones, boil them in a pot of water, strain it all through a colander, and drink it down like tea.
