The Misuse of Drugs Act (MDA) is the main legislation for drug offences. The First Schedule of the MDA is a list of controlled drugs which are classified into Class A, B and C. The MDA spells out the offences involving controlled drugs and substances in relation to trafficking, manufacturing, importation or exportation, possession and consumption.

The MDA empowers the Director of CNB to commit a drug abuser for treatment and rehabilitation in a drug rehabilitation centre for between 6 and 36 months. It also provides for long term imprisonment regime for recalcitrant abusers of specific drugs listed in the Fourth Schedule of the MDA (e.g. diamorphine, buprenorphine, methamphetamine, ‘Ecstasy’, ketamine and nimetazepam).
