Schedule 2 Controlled Drug Storage Requirements for Cannabis

Legal Framework: The Misuse of Drugs (Safe Custody) Regulations

• Cannabis stored in pharmacies and clinics must comply with the Misuse of Drugs (Safe Custody) Regulations 1973
• Schedule 2 drugs require storage in a locked cabinet constructed to specified security standards (BS 2881 or equivalent)
• Cannabis must be stored separately from other controlled drugs where practicable
• Temperature and humidity conditions must be maintained to preserve product quality — typically 15–25°C, <60% RH

The storage of Schedule 2 cannabis is a legal requirement, not merely best practice. Pharmacies and healthcare facilities that dispense or hold cannabis products must ensure their storage facilities meet the required security specifications. Failure to comply with the Safe Custody Regulations is a criminal offence and can result in the loss of the facility’s controlled drug licence.

Physical Security Requirements for Cannabis Storage

• Locked cabinet: steel construction, minimum 2mm gauge, mounted to wall or floor — cannot be removed
• Key security: cabinet key held by the responsible pharmacist or designated controlled drug liaison officer only
• Access control: a register of cabinet access must be maintained — who opened it, when, and for what purpose
• CCTV coverage of the storage area is strongly recommended as a deterrent and for investigation purposes

The physical security requirements for cannabis storage reflect its Schedule 2 status as a drug with significant misuse potential. Facilities must conduct regular security audits of their controlled drug storage arrangements and document the results. Any breach of security — lost keys, damaged cabinet, unauthorised access — must be reported to the Home Office Drugs Licensing and Compliance Unit.

Controlled Drug Register: Record-Keeping Requirements

• Every cannabis transaction (receipt, dispensing, disposal) must be recorded in a bound, consecutively numbered register
• Entries must include: date, quantity received or dispensed, running balance, patient name (for dispensings)
• Registers must be retained for two years after the date of the last entry
• Electronic controlled drug registers are now accepted, provided they meet NICE/NHS England requirements for security and auditability

The controlled drug register is the definitive audit trail for cannabis stock in a licensed facility. It must be accurate, complete, and reconcilable at all times. Regular stock audits — matching physical stock against the register balance — should be conducted monthly at minimum, and weekly in high-volume dispensing settings. Any discrepancy must be investigated immediately and reported to the Accountable Officer.

Waste, Expired Stock, and Surplus Product Disposal

• Expired or unused cannabis cannot be disposed of by pharmacies — it must be returned to an authorised collector
• Patient returns of cannabis at a pharmacy must be received and disposed of via a licensed controlled drug waste contractor
• Denaturing cannabis prior to disposal is no longer required but may be conducted under controlled conditions
• All disposals must be recorded in the controlled drug register with the quantity and method

The disposal of cannabis waste is a regulated activity that pharmacies cannot manage unilaterally. Relationships with licensed controlled drug waste contractors should be established before beginning cannabis dispensing activity. The cost of waste disposal should be factored into the pharmacy’s cannabis service model, as it is a recurring overhead that cannot be avoided.
