N,N-Dimethyl-5-Methoxytryptamine (aka 5-MeO-DMT) is a psychedelic of the tryptamine class. It is found in a wide variety of plant species, and a single psychoactive toad species, the Colorado River toad. Like its close relatives DMT and bufotenin (5-HO-DMT), it has been used as an entheogen in South America. It can also be found in the dart poison traditionally used by the Yanoama Indians of Upper Orinoco. It acts as a non-selective serotonin (5-HT) agonist. -MeO-DMT is O-demethylated by polymorphic cytochrome P450 2D6 (CYP2D6) to an active metabolite, bufotenine. 5-MeO-DMT is classified as a controlled substance in China, Australia, Sweden, Turkey, and the USA.

Bremazocine, a kappa-opioid agonist has limited potential as a clinical analgesic, however, possesses a possible utility for the therapy of alcohol and drug addiction. It was shown that bremazocine-like drugs could lower intraocular pressure and to minimize ischemic damage, that could be used in the therapy of glaucoma and cardiovascular disease.

Muscimol is one of the principal psychoactive constituents of Amanita muscaria and related species of mushroom. Muscimol is a potent, selective agonist for the GABAAreceptors and displays sedative-hypnotic, depressant and hallucinogenic psychoactivity. The effects of the Amanita mushrooms begin 30–120 minutes after consumption and the effects last for 5–10 hours. Some of the desired effects include euphoria, dream-like (lucid) state of mind, out-of-body experiences, and synesthesia. Neutral effects include dizziness, clumsiness, the feeling of increased physical strength, loss of equilibrium, and a glassy-eyed stare. Calming effects may be felt, but completely opposite effects such as extreme energy bursts have been described. Negative effects include mild to moderate nausea, stomach discomfort, increased salivation, and muscle twitching or tremors. In large doses, strong dissociation or delirium may be felt.
