Indoor Marihuana Growing Operations

A recent drug trend has found it’s way to the Winnipeg area. Sophisticated indoor

marihuana grows, although not new to Winnipeg, have been turning up with

regularity in middle and upper-middle class residential neighborhoods of the city.

Winnipeg Police are discovering these commercial operations on a weekly basis

and are observing first hand a number of safety hazards that are putting our

neighborhoods at risk. They include:

DANGERS TO PUBLIC SAFETY

The following are some of the public safety hazards caused by indoor marihuana grow

operations.

Fires

Diverting electricity and tampering with electrical wiring

can lead to house fires. The use of extra exhaust fans

in the grow operation can accelerate the fire increasing

the hazard. This hazard extends not only to the house

where the indoor marihuana grow is located, but also

the homes surrounding it in the neighborhood.

Estimates are as high as one in ten that indoor

marihuana grows will catch fire. In Winnipeg we have

already seen these types of fires as recently as

December 2002.

Power Outages

Overloading the power system can cause hydro transformers to blow resulting in power outages

in entire neighborhoods. This type of incident occurred in December 2002 in north Winnipeg.

Poisonous Gases

The re-venting of the furnace to circulate the air to feed the marihuana plants can circulate

exhaust fumes from the furnace back into the house.

There can be a build up of poisonous gases from the chemical nutrients used in the production of

the marihuana crop. These poisonous gases are circulated inside the house and also vented to

the outside and released into the neighborhood.

Explosions

The combination of solvents and oxygen from the exhaust fans in "weed oil extraction labs" can

cause an explosion. (Last year in Boucherville, Quebec, a house exploded in one of these “weed

oil extractions labs. It caused $1,000,000 damage to neighboring homes.)

Violence

The ability for the growers to make a massive profit prompts them to arm themselves to protect

themselves and their operation. (In British Columbia, one in eight homicides is related to the

marihuana grow industry).

There is increasing evidence of kidnappings; extortion and home invasions linked to the

marihuana grow industry. In Summer 2002 Winnipeg Police discovered an indoor grow operation

that had been invaded by members of a local street gang.

Booby Traps

Often residences that house indoor marihuana grows are "booby trapped" to target unauthorized

entry (e.g. live wires on door handles, spikes exposed in entranceways). This can cause injury or

even death to emergency responders (e.g. firefighters, paramedics, police), newspaper carriers,

or even innocent children who happen to wander on to the property.

Structural Damage to Homes

Often the houses that are rented for

indoor marihuana grows are altered

to be able to grow more product.

Foundations walls are drilled

through to facilitate illegal wiring.

Unhealthy mold and fungus caused

by condensation build up from the

grow operation builds up inside the

house and can eat through the roof

of a house in only a few years.

Many times, these homes cannot

be renovated, and must be

destroyed since they are unsafe t
