List of investigational hallucinogens and entactogens
This is a list of investigational hallucinogens and entactogens, or hallucinogens and entactogens that are currently under formal development for clinical use but are not yet approved.
Chemical/generic names are listed first, with developmental code names, synonyms, and brand names in parentheses. The list also includes non-hallucinogenic drugs related to hallucinogens, such as non-hallucinogenic serotonin 5-HT2A receptor agonists and non-hallucinogenic ketamine analogues. Cannabinoids, or cannabinoid receptor modulators, are not included in this list. Many of the indications are not for continuous medication therapy but rather are for medication-assisted psychotherapy or short-term use only. The section that the drug is in corresponds to its highest developmental phase, not its phase for all listed indications.
This list was last comprehensively updated in October 2024. It is likely to become outdated with time.
