Current drug therapies for treating psychiatric disorders, such as depression and anxiety, are often associated with limited benefits and significant side effects. However, recent research has shown promising results for psychedelic drugs like psilocybin, DMT, and LSD, which induce profound alterations of consciousness by activating a specific serotonin receptor called 5-HT2A. These drugs have been shown to produce long-lasting reductions in depression and anxiety after only one or two doses.

While these psychedelic drugs have shown great potential, their intense hallucinogenic effects make them difficult to tolerate for many patients. Therefore, researchers have been investigating whether it is possible to decouple the hallucinogenic effects of these drugs from their therapeutic effects. A recent study has shown that it may be possible to do so with a compound called 2-bromo-lysergic acid diethylamide (Br-LSD).

Br-LSD is a compound that has been synthesized from LSD, but it has no hallucinogenic effects in humans. Recent studies have shown that Br-LSD promotes neuroplasticity and reduces the loss of synaptic connections in the cortex associated with depression. Increased neural plasticity is thought to underlie the therapeutic response to antidepressant drugs. Treatment with Br-LSD has also been shown to promote the exploration of novel environments that usually induce stress, as well as improved coping behaviors.

Importantly, Br-LSD has less potential for side effects than other drugs that act on serotonergic neurons. This is likely due to the fact that it is a weaker stimulant at the 5-HT2A receptor. Five patients who received 30 mg/kg Br-LSD on three occasions experienced only minor side effects. Higher oral doses (64–256 mg/kg) induced mild subjective responses, including restlessness, anxiety, drowsiness, impaired concentration, and euphoria. None of the subjects who received 2-Br-LSD orally or intravenously experienced visual hallucinations or profound cognitive alterations similar to those induced by LSD.

These findings suggest that Br-LSD has the potential to be an effective treatment for major depressive disorders and anxiety, possibly through its effects on neuroplasticity. Compounds modifying synaptic plasticity are considered promising therapies for these disorders. Additionally, the lack of Br-LSD tolerance may permit frequent dosing for mood disorders and other indications.

While the use of psychedelic drugs to treat psychiatric disorders is still in its early stages, the potential benefits of compounds like Br-LSD are exciting. Further research is needed to fully understand the therapeutic potential of these drugs and to determine the most effective dosages and administration methods. Nevertheless, these findings offer hope for patients who have not responded well to traditional drug therapies for depression and anxiety.
