Is Synthetic Cannabinoids (K2 / Spice) legal in United Kingdom?
- Legal status
- Controlled as a class. The first and second generations of synthetic cannabinoids (JWH-, AM-, naphthoylindole 'Spice'/'Black Mamba' compounds) were caught by generic definitions inserted into the Misuse of Drugs Act 1971 as Class B drugs (2009 and 2013), and the 'third generation' synthetic cannabinoids were brought under a wider generic definition as Class B by the Misuse of Drugs Act 1971 (Amendment) Order 2016 (SI 2016/1109), in force December 2016. The blanket Psychoactive Substances Act 2016 is a backstop for any synthetic cannabinoid the generics miss.
- Consequences if caught
- Illegal as Class B drugs: possession up to 5 years, supply/production up to 14 years plus unlimited fine. No death penalty.

- Synthetic cannabinoids of this class have no recognised medical use and no lawful prescription route in the UK (Schedule 1, Misuse of Drugs Regulations 2001).
- Documentation
- No lawful personal-import route for these controlled Class B substances; do not carry.
