Theft of controlled drugs from pharmacies is a real threat across the UK. Rules require secure storage, but there is a gap between ticking the compliance box and actual protection — especially against serious theft attempts. A layered security approach closes this gap.
The regulatory framework
The Misuse of Drugs (Safe Custody) Regulations 1973 say controlled drugs must be kept in a locked safe, cabinet, or room. The Controlled Drugs (Supervision of Management and Use) Regulations 2013 go further: pharmacies must appoint an Accountable Officer to oversee CD security systems.
The General Pharmaceutical Council (GPhC) Standards state that security of premises and stock is essential. NICE guidance (NG46) reinforces this. British Standard BS 2881 Security Level 2 sets a clear target: no entry in 15 minutes of planned attack.
Compliance failures carry real consequences: regulatory action, damage to reputation, and criminal liability. Yet the rules specify what to store drugs in — not what happens when someone tries to break in.
Why a safe and alarm are not enough
A locked safe deters casual theft. An alarm alerts responders after a break-in.
Neither stops a theft in progress. A determined intruder will attack the safe, cut a cabinet, or raid the dispensary after hours when only an alarm is working. They may smash glass, pry open doors, or use tools to force the lock. By the time responders arrive, drugs may already be gone.
97% of thefts are avoided with a fogging system AND an alarm, compared with 17% with an alarm only. This Density® manufacturer figure shows the value of layering active protection with passive controls.
The gap is the time between breach and response. Minutes matter. Active security — rapid fog that fills the space in seconds — closes this gap and stops the theft before it happens.
How fog stops theft in seconds
Security fog deploys in seconds, filling space with thick, impenetrable fog that blocks sight completely. A thief cannot see where anything is, cannot navigate safely, cannot identify or reach the safe or stock. Fog persists for hours. Visibility only returns if the intruder clears it from outside — a process that creates more delay and raises the risk they are caught.
The UNIK system is compact and covers up to 600 cubic metres. It needs no heat and runs on battery for up to six months, so it works during power cuts or after-hours attacks when mains power may be compromised. The fog is non-toxic (certified by Eurofins) and safe around food and medicines. No staining, no residue, no harm to stock or equipment.
Fog works alongside your safe and alarm, not instead of them. The safe holds stock securely. The alarm alerts responders immediately. Fog makes the intrusion pointless, buying time for responders to arrive and for the offender to abandon the attempt.
Works with your alarm and monitoring
Fog systems work with all alarm panels, including Ajax. Remote monitoring is available via ActiveCloud. If you use CCTV, fog systems integrate so deployment is logged with video (via API and LAN). When an alarm triggers, responders know fog is active. When incidents are reviewed, you have video and fog logs together.
For your Accountable Officer, this creates a clear record: environmental controls were in place and they worked. This is evidence of due diligence.
The system meets EN 50131-8:2019, the same standard as your alarm panel.
Protects all dispensary stock
Controlled drugs are not the only target. Antibiotics, painkillers, anxiety meds, and ADHD treatments are all valuable. Fog at dispensary entry points protects the whole supply. For pharmacies with multiple dispensaries, Density systems scale from 600 m³ (UNIK, ideal for single rooms) to 14,000 m³ (HP14000, for large spaces). Each is tailored to your space.
Accountable Officer and compliance
Your Accountable Officer must document CD security systems. Fog logs (integrated with your alarm) show you took active steps to protect stock. This is evidence of due diligence, not just a tick box.
Reliability and safety
Fog systems are tested and certified like alarm systems. Battery power and zero heat mean the system works during power cuts. The fog is non-toxic (certified to EN ISO 16000-1:2006) and safe for staff and responders. No harm to medicines or equipment.

Frequently asked questions
Do I need fog if I have a safe and alarm?
A safe and alarm meet the law. Fog adds active protection that stops theft happening — not just detecting it after. The 97% rate with fog plus alarm (versus 17% with alarm only) shows the real benefit. Your choice depends on your risk level and location.
Will fog damage my medicines or equipment?
No. The fog fluid is non-toxic, certified by Eurofins for human and animal safety, and tested to food-contact standards (Reg. CE No. 1935/2004). It does not corrode shelves, refrigeration units, or other equipment. It does not stain or contaminate medicine stock. Once activated, fog dissipates naturally over several hours; there is no sticky residue or cleanup required.
How does fog integrate with my existing alarm system?
Fog systems are compatible with all alarm panels and can be triggered manually or integrated with the alarm’s activation logic. Remote monitoring is available via ActiveCloud. Integration with CCTV or VMS systems is supported via API and LAN connectivity, so fog deployment is logged and correlated with video evidence.
What size system for my pharmacy?
Coverage is measured in cubic metres (m³), not floor space. A single room needs 600 m³ (UNIK or 600 Lite). Multi-room areas need larger systems. A site survey will find the right fit.
Is fog legal and compliant?
Yes. Fog is a supplement — it does not replace your safe or alarm. It meets EN 50131-8:2019 and fits your Accountable Officer’s security plan. Pharmacies and healthcare facilities use it across the UK and in 80+ countries.
CD security is a legal and operational duty. Layered protection — safe, alarm, and active fog — meets rules and cuts theft risk. Explore pharmacy security or contact us for a site survey and no-obligation consultation.
