How Psychedelic or Hallucinogenic Drugs Work

Although the salient features of psilocybin intoxication are blocked by the selective 5-HT2A antagonist ketanserin (Vollenweider et al., 1998), psilocin also has significant agonist activity at the 5-HT1A receptor (e.g., Blair et al., 2000). It is unknown to what extent intravenous administration of psilocybin might produce effects on neuronal function through activation of 5-HT1A receptors. Halberstadt and Geyer recently reviewed the Psychedelic topic of serotonergic hallucinogens as translational models relevant to schizophrenia. In their review, they note the many early groups that studied the effects of LSD, mescaline, and psilocybin, who concluded that these drugs produced mental states that resembled the earliest phases of schizophrenia. The four widely used animal behavioral models are startle habituation, PPI, HTRs in rodents, and deficits in temporal processing .

There have been dozens of deaths reported as a direct result of Brugmansia ingestion and plenty of examples of psychotic breaks. Aside from the negative hallucinogenic effects of this plant, datura has direct toxic effects that can even lead to death. It contains a series of anticholinergic compounds that can lead to respiratory depression, irregular heart rate, fever, permanent psychosis, and death. Most of the problems people experience while using these psychedelics come from accidents that happen while using the drug — such as carelessly walking out onto the road or wandering into other dangerous situations in an inebriated state . Aside from the potential for causing scary trips, it’s extremely uncommon for any of these substances to cause any serious side effects — even in very high doses.

Bath salts alter the perception of reality, remove inhibition, and induce states of intense panic, fear, or rage. It’s common for people using these drugs to climb buildings, jump through glass, or otherwise cause severe bodily harm to themselves or others. However, the severe neurotoxic side effects of this drug lead regulators to ban the drug as soon as there was a viable alternative – namely ketamine. What really makes it so dangerous is its ability to remove the ability to form memories and the destruction of your ability to make decisions. It traps your consciousness and turns you into a zombie — stripping away your ability to make decisions of your own free will.

That is, serotonin activation leads to a signaling complex that involves β-arrestin-2, Src, and Akt, whereas N-methylated derivatives produce the HTR through a signaling mechanism that is independent of β-arrestin-2 and does not require activation of Akt. Bohn and Schmid reviewed functional selectivity of the 5-HT2A receptor and the role of arrestin as one of the signaling pathways. To disrupt the function of the signaling complex in vivo, the HTR in normal C57BL/6J mice was assessed after intracerebroventricular administration of inhibitors of PI3K, Src, and Akt prior to treatment with 5-HTP. By contrast, pretreatment of β-arrestin-2 KO mice with PI3K, Src, or Akt inhibitors prior to 5-HTP did not reduce the HTR, suggesting that the HTR in β-arrestin-2 mice is independent of these signaling components. Schmid and Bohn suggested that the HTR induced by high doses of 5-HTP or serotonin in WT mice could reflect activity of both serotonin and its N-methylated derivatives. Thus, when WT mice were pretreated with the Akt inhibitor together with an N-methyltransferase inhibitor prior to 5-HTP, the HTR was nearly abolished.

The functional brain imaging showed an increase in regional CBF in both anterior regions and an even more pronounced increase in right anterior cortical regions, indicating a pattern of hyperfrontality. The authors note, however, that it was not known how CBF correlated with neuronal activity. Acute neurometabolic effects of psilocybin in humans also were initially measured on the regional cerebral metabolic rate of glucose in humans using FDG PET in the laboratories of Vollenweider et al. and Gouzoulis-Mayfrank et al. . Even with the development of modern brain scanning technologies, however, the overall action of psychedelics in the brain is far from being understood.

They also propose that entry into primary states depends on the collapse of the normally highly organized activity within the DMN and a decoupling between the DMN and the medial temporal lobes that are normally significantly coupled. The functional centrality of the DMN is not shared by other brain networks, implying that as the highest level of a functional hierarchy, the DMN serves as a central orchestrator or conductor of global brain function. The net effect of these processes is an increase in system entropy as the system enters criticality proper. Specifically, it is proposed that psychedelics work by dismantling reinforced patterns of negative thought and behavior by breaking down the stable spatiotemporal patterns of brain activity upon which they rest.
