Many hallucinogenic drugs , such as ecstasy, LSD, and DMT, are made by chemical synthesis. But nature is also a clandestine laboratory for psychedelic substances. For example, the mushroom Stropharia cubensis synthesizes a powerful drug, psilocybin. Other vegetables, such as the parasitic ergot fungus, the seed of the glory day flower, Turkestan mint ( Lagochilus inebrians ), and two species of Mexican cacti make hallucinogens.
There are also psychoactive substances of animal origin. Some species of frogs , such as the Peruvian Phyllomedusa bicolor, and toads , such as those of the genus Bufo , secrete toxins on their skin that cause hallucinations when ingested or smoked.
