How to spot a Cannabis farm and how to report

These farms are often hidden in residential or commercial properties. Here are common indicators:

1. Covered or Blacked-Out Windows

Curtains or blinds always closed.

Windows covered with reflective material or black plastic.

2. Strong, Pungent Smell

A distinctive, sweet, skunky smell, especially noticeable at certain times of day or from vents.

3. Excessive Heat

Cannabis farms generate a lot of heat. In winter, snow may melt quickly on the roof of a property compared to neighbouring houses.

4. Constant Hum or Buzzing

The sound of fans, ventilation systems, or hydroponic equipment running continuously.

5. High Levels of Condensation

Water droplets on windows, even in warm weather.

6. Unusual Activity

People visiting at odd hours, often briefly.

Rarely seeing the occupants, or seeing different people frequently.

7. Tampered or Bypassed Electricity

Signs of electrical tampering or unusually high electricity use.

GMP often finds electricity abstraction (illegal tapping into the grid) during raids.

Do not approach or investigate the property yourself.
