Why the 1971 treaty excludes alcohol and tobacco from international control
In short: The Convention on Psychotropic Substances regulates everything from LSD to benzodiazepines, yet leaves alcohol and tobacco untouched. It is not because they are harmless, but because the treaty's specific administrative tools were deemed unsuitable for managing their widespread social impact.
Signed in Vienna on 21 February 1971, the Convention on Psychotropic Substances was created to address a regulatory gap. While the 1961 Single Convention on Narcotic Drugs controlled substances like opium, cannabis, and cocaine, it lacked the scope to regulate the surge of newly discovered synthetic psychotropics appearing in the 1960s. This led to a global framework that now includes amphetamine-type stimulants, barbiturates, and hallucinogens.
The treaty's architecture relies on four distinct Schedules, ranging from the highly restrictive Schedule I—which includes LSD and MDMA—to the less restrictive Schedule IV, containing substances like modafinil. Adding a drug to these lists is a rigorous process: the World Health Organization (WHO) must first assess the substance's impact on public health, its potential for dependence, and its medical utility. The Commission on Narcotic Drugs then makes the final decision, weighing economic and social factors alongside the WHO's scientific findings.
A fascinating nuance lies in why the treaty ignores other psychoactive substances. According to the treaty's Commentary, alcohol and tobacco were excluded not for a lack of harm, but for a lack of 'suitability.' While alcohol causes significant social problems and dependence, the administrative measures of the Vienna Convention were not considered an effective way to alleviate the alcohol problem. Similarly, tobacco was deemed unsuitable for the specific controls provided by this framework, illustrating that international drug control is as much about administrative feasibility as it is about chemical potency.
