Controlled Drug

Controlled drugs are substances regulated by the UK government due to their potential for addiction, misuse, and harm. Their production, supply, possession, storage, and destruction are subject to strict legal controls under the Misuse of Drugs Act 1971 and the Misuse of Drugs Regulations 2001.

They are classified into five schedules under the Misuse of Drugs Regulations 2001:

  • Schedule 1: No recognised medicinal use (e.g., LSD, cocaine).
  • Schedule 2: Includes opioids (e.g. morphine, oxycodone) and medical cannabis, requiring strict prescription controls.
  • Schedule 3: Includes tramadol, pregabalin, and midazolam, which have fewer storage restrictions than Schedule 2 drugs.
  • Schedule 4: Includes benzodiazepines and anabolic steroids, which have some restrictions but don’t require prescription record-keeping.
  • Schedule 5: Includes low-strength opioid medicines, such as certain codeine preparations, with minimal restrictions.

Unlicensed medical cannabis is classed as a Schedule 2 controlled drug and it can only be initiated by a specialist clinician.
