Overview

Morphinans are a class of psychoactive drugs consisting of opioid analgesics, cough suppressants, and dissociative hallucinogens, among others. PW

Morphinan is the prototype chemical structure of a large chemical class of psychoactive drugs, consisting of opiate analgesics, cough suppressants, and dissociative hallucinogens, among others. Typical examples include compounds such as morphine, codeine, and dextromethorphan (DXM). Despite related molecular structures, the pharmacological profiles and mechanisms of action between the various types of morphinan substances can vary substantially. They tend to function either as μ-opioid receptor agonists (analgesics), or NMDA receptor antagonists (dissociatives).[1] WP

Drugs in this class on intoxicant.wiki

Every page on this site that a cited source puts in this class: 13 pages. A drug is listed when PsychonautWiki's "Substituted morphinans" page, revision 160420 lists it, or when its own PsychonautWiki, TripSit or Wikipedia entry names this class. Each name opens our page for that drug; long chemical names are shown by a shorter name the drug is also known by (hover for the full name).

Tags show who puts each drug in this class (hover for the exact wording): PW list = listed on PsychonautWiki's page for this class; PW = the drug's PsychonautWiki entry; TS = the drug's TripSit entry (drug category); WP = the drug infobox of the drug's Wikipedia article. These are classifications only, not dosage guidance.
