Stimulants, Psychoactive Plants, and Human Optimization: Medical Gatekeeping, Prohibition, and Adult Autonomy in Drug Policy
International Journal For Multidisciplinary Research July 4, 2026 Eric P. Rubenstein
Drug policy around stimulants and performance-enhancing substances is shaped less by pharmacological risk than by cultural familiarity, medical gatekeeping, market authorization, colonial history, religious-moral inheritance, social ritual, fiscal integration, workplace pressure, and state utility. Caffeine, nicotine, energy drinks, prescription stimulants, alcohol, and other accepted practices all carry risks, yet some are normalized, commercialized, and taxed while others are criminalized. The paper introduces self-directed activation and optimization as a regulatory concept and proposes a Liberty, Harm, and Intervention Threshold Test for evaluating substances. It argues that criminal prohibition requires justification grounded in concrete harm, coercion, or failure of less restrictive alternatives, and advocates for a liberty-preserving model distinguishing concrete harm from adult self-risk.
