New Psychoactive Substances (NPS)

NPS are substances of abuse, either in a pure form or a preparation, that are not controlled by international drug conventions, but which may pose a public health threat. In this context, the term "new" does not necessarily refer to new inventions but to substances that have newly become available in specific markets. In general, NPS is an umbrella term for unregulated (new) psychoactive substances or products intended to mimic the effects of controlled drugs.
