Marijuana Grow Operation BCGrow ops in BC continue to plague communities and Kamloops is not immune to this problem. Each grow operation presents many risks to the communities they exist in, such as drug traffic through the community and community safety related to this traffic. Marijuana production continues to be a multi-billion dollar industry in B.C. with thousands of charges laid against operators each year. There are endless stories of grow op busts of all sizes but the problem persists in B.C. and doesn’t seem to be slowing down anytime soon.

What is a Marijuana Grow Operation?

Marijuana Grow Ops appear in homes or outbuildings in residential, rural or commercial/industrial areas. These operations can occur in apartments, small bungalows, large multi-million dollar homes and commercial buildings. The buildings appear to be fairly well maintained and don’t look out of the ordinary however the internal structure may have received significant structural, electrical and heating system modifications that are not up to code or deemed safe.

Changes to these systems are done to replicate warm, humid climates in which hybrid plants flourish to produce high potency marijuana. Structures that were previously Marijuana Grow Ops are often unsafe for human occupancy. This is because of compromised structural and mechanical integrity, as well as hazards from mold (mould) and chemical residue.

How to detect a Marijuana grow operation when purchasing a home.

When purchasing a home it is important to do all the appropriate tests and inspections to safeguard your purchase. A thorough environmental assessment which includes an air quality and mold inspection should be conducted. A proper inspection for mould should be thorough and include numerous air samples (spore test) and visual inspection of the structure. These comprehensive tests will survey the air quality to identify and locate hidden pollution and mould levels indoors. These tests will identify any areas that had previous grow operations and contain abnormal levels of mould or chemical pollution. These agents alone can cause serious health problems leading to long term conditions.

A listing Realtor is required by the Canadian Real Estate Association to have a home owner fill out a Property Condition Disclosure Statement. This statement is filled out by the home owner and requires a home owner to disclose any “material latent defects” such as a grow operation that cannot be detected with reasonable investigation. Grow op owners can and have hidden obvious signs of a previous grow operation and not disclosed it in this form. A potential buyer unfortunately has to search deeper before assuming all facts are disclosed by the homeowner. Talking to neighbours and local authorities often can uncover information.

  1. I found suspicious bottles of neem oil, and nutrients in my neighbor’s trash (the wind had blown it over). There was a lot of different bottles, and after looking some of them up online it looks like they are commonly used by marijuana growers. Maybe you should add that to this list – suspicious trash or waste including nutrients, plant material, etc.
