Mescaline, a classic psychedelic with a history of indigenous ceremonial use, is being reexamined for psychiatric therapy. It works primarily by activating serotonin-2A receptors. Most modern safety data come from healthy volunteers, leaving its effects in patients with cardiovascular, metabolic, or psychiatric conditions unclear. Randomized, placebo-controlled studies show mescaline produces dose-dependent subjective effects with moderate, temporary autonomic stimulation and no serious complications under controlled conditions. Adverse effects are generally self-limiting, and pooled analyses indicate a favorable safety profile in screened populations. Controlled clinical trials are needed to establish its safety and therapeutic potential in patient groups.
