Psychedelic drugs have long aroused fascination in humans because of their property of producing an altered state of consciousness characterized by distortions of perception, hallucinations and a state of ecstasy. speed upspeed Found naturally in certain plants, such as magic mushrooms of the genus to Psilocybe, these drugs have been used for centuries, if not millennia, in the This structural analogue, called tabernanthalog (TBG), can be synthesized medical and religious practices of many cultures. in a single step and, like ibogaine, has the property of stimulating the growth and networking of neurons, a neuronal reprogramming which The discovery in the 1940s and 1950s that hallucinogenic drugs such as seems to play an important role in the positive effects of addiction drug. lysergic acid diethylamide (LSD, synthesized from lysergic acid in rye ergot) and (the active ingredient in Psilocybes) could enhance On the other hand, and unlike ibogaine, the analogue TBG does not seem self-awareness and facilitate recollection and the release of emotionally to cause any hallucinations in treated animals (no repeated contractions of charged memories sparked immense interest at the time in the use of these the head, a sign known to correspond to hallucinations) and is much less ?
