LSD - Treatment for Patients with Alcohol Dependence
Descrizione riassuntiva dello studio
Hallucinogens (substances that cause changes in thinking and perception, e.g., LSD) may potentially improve the symptoms of alcohol dependence. This study investigates the efficacy of a medium to high dose of lysergic acid diethylamide (LSD) compared to a low dose of LSD (active placebo) as treatment for patients with alcohol dependence. The focus is particularly on the risk of relapse after alcohol withdrawal. Participants are randomly assigned to the high-dose group or the low-dose group (placebo). The high-dose group receives 150 µg of LSD in the first substance session and 150 µg or 250 µg of LSD in the second substance session. The placebo group receives 10 µg in the first substance session and also 10 or 20 µg in the second substance session. In addition to efficacy in alcohol dependence, microstructural changes in the brain are also examined over the course of the study using MRI. Furthermore, group treatments are compared with individual treatments.
