Psychedelics and quasi-psychedelics in the light of contemporary research medical cannabis, MDMA, salvinorin A, ibogaine and ayahuasca.
In lack of professional research and appropriate concepts our scientific knowledge of psychedelic agents is limited. According to the long-held official view these drugs are entirely harmful and have no medical use. However, a recent surge of clinical and pharmacological studies in the field indicates that many psychedelic-like agents have therapeutic potentials under proper circumstances. In this paper, from a biomedical and psychological perspective, we provide a brief review of the general effects and promising treatment uses of medical cannabis, 3,4-methylenedioxy-methamphetamine (MDMA), salvinorin A, ibogaine and the dimethyltryptamine-(DMT)-containing ayahuasca. In Hungary - similarly to many other countries - these compounds are classified as narcotic drugs and their research is difficult due to strict regulations.
