Oregon Warns Marijuana Growers Against Illegal Pesticides

The Oregon Department of Agriculture said Wednesday it has drawn up a pesticide advisory, which the Oregon Health Authority is sending to registered medical marijuana growers around the state.

Earlier this summer, Colorado announced plans to crack down on pesticide use in the pot industry after thousands of plants were found treated with unauthorized chemicals.

The advisory says no pesticides have been specifically approved for use on marijuana, which is still illegal on a federal level, and the health and safety impacts on cannabis workers have not been evaluated.

Department of Agriculture spokesman Bruce Pokarney says rules for pesticide use are being drawn up along with a host of other rules for growing and selling retail marijuana.

Full retail marijuana sales are not to begin until late in 2016, but in October medical marijuana dispensaries can start selling limited amounts to anyone over 21.
