The use of psychedelics has been a long-standing topic of interest in the fields of psychology, neuroscience, and pharmacology, with these substances having been used for centuries in various cultures for their therapeutic and metaphysical properties. In recent years, there has been a revival in the research and development of psychedelics as potential treatments for cognitive impairments, such as existential dread, anxiety, and post-traumatic stress disorder (PTSD).

From a pharmacological perspective, psychedelics act on the brain's neurotransmitter systems, especially the serotonin system, to produce their effects. Serotonin is a neurotransmitter that plays a crucial role in regulating mood and perception. Psychedelics, such as DMT, are classified as brain-active agents, meaning they interact with the serotonin receptors in the brain.

Psilocybin, the active compound in magic truffles kaufen mushrooms, is a potent inhibitor of the serotonin transporter, a protein that regulates the reuptake of serotonin from synapses. By blocking this protein, psilocybin increases the amount of serotonin available in the synaptic cleft, where it can bind to serotonin receptors and produce its outcomes. These effects include modifications in perception, such as changes in subjective experience, and increased feelings of self-insight.

LSD, on the other hand, is a non-selective serotonin receptor agonist, meaning it binds to multiple serotonin receptors with consistent affinity, producing a wide range of effects. LSD is known to bind to the 5-HT2A receptor, which is involved in the modulation of perception and awareness. Activation of this receptor is thought to play a role to the psychedelic effects of LSD, including motions in reality processing, visions, and modified sense of self.

DMT, a short-acting psychedelic, is produced endogenously in the brain as a neurotransmitter and is also found in various plants and animals. DMT is thought to interact with the 5-HT2A receptor in a similar fashion as LSD, producing intense perceptual modifications and altered states of awareness.

In contrast to other psychoactive substances, such as opioids and benzodiazepines, psychedelics have a comparatively low tendency to addiction and are typically not associated with withdrawal symptoms. This is thought to be due to their unique mechanism of action, which involves modulation of serotonin receptors rather than dopaminergic systems, which are more commonly associated with addiction.
