NPS, as well as other drugs and medicines, may be described as being ’controlled‘ or ’not controlled‘ by law. To ‘control’ psychoactive substances, an international drug control system exists. This systems contains three international conventions (agreements) set up by the United Nations in 1961, 1971, and 1988.
To NPS, only the conventions of 1961 and 1971 apply. In these agreements, substances are ranked according to their risk for abuse and therapeutic or medical value. Substances on Schedule I, such as MDMA or LSD, are considered most dangerous, and are most strictly controlled. The international drug control agreements do not, however, require any country in the UN to treat the consumption of drugs as a punishable act (as opposed to possession of drugs).
National and international
NPS will not immediately be under national or international control. NPS are often newly developed chemical compounds which are therefore not yet known and listed in drug schedules. So at first instance, the substance will be allowed to be produced, sold and bought. When an NPS is discovered by law enforcement and/or laboratories, and reported to national or European ‘early warning systems’ for new drugs, it will be monitored how much (health) harms a substance causes in society. When the (possible) damage has been evaluated, it may be decided to control a new substance. It will then be added to a (national or international) scheduling list for ‘illegal drugs’. Production, trafficking, trade, and possession of the substance are thereby made strictly controlled (or punishable) acts.
World Health Organisation
Through the website of the World Health Organisation, the lists with all substances under international control can be found. The WHO evaluates the risks of psychoactive substances, and then gives advice on which should be put under international control (and under which schedule). Individual countries can also place substances or entire chemical substance groups under control through national drug laws, even when these substances are not (yet) under international control. For information on which substances and/or substance groups are controlled in your country, please check your country’s webpage through this website.
