Ayahuasca (yajé), a hallucinogenic substance used since ancient times by Indigenous communities in South America for mystical, divinatory, and religious purposes, is now appearing in urban settings with new meanings and characteristics. This study analyzed motivations for yajé consumption among 40 people in Bogotá, Colombia, who had used it two or more times, using a validated motivation scale and semi-structured interviews with four participants. The main motivations for repeated use were therapeutic and emotional: individuals sought psychic well-being, including tranquility, inner peace, mental clarity, and resolution of personal stagnation or life problems.

More than 2% of the Spanish population reports having used LSD. The drug acts through serotonergic, dopaminergic, and glutamatergic neurotransmitter systems. LSD and its analogs have been used as experimental psychotomimetics, but rapid tolerance to subjective effects and visual hallucinations undermines the hallucinogen-psychodelic model of schizophrenia. The most frequent adverse psychic effects following LSD use or abuse are anxiety disorders, mood disorders, perceptual disorders (hallucinogen persisting perception disorder, flashbacks), and psychotic disorders. Treatment of these adverse effects is symptomatic, with anxiolytics and antipsychotics most commonly used. The potential therapeutic use of LSD in psychedelic therapies and alcoholism is discussed, but with limited impact. LSD and other hallucinogens are used recreationally but carry a risk of psychic harm that can be prevented and adequately treated.

Including DMT in chemical submission protocols is recommended when victims may have attended spiritual rituals or when patients report brief but intense visual and auditory hallucinations. DMT can cause false positive results in amphetamine screenings, which may indicate its presence, though not all screening methods are equally affected.
