Like most industries, marijuana production can also create toxic waste.
In many ways this is unavoidable; however, Washington growers follow
EPA guidelines and work with a professional hazardous waste disposal
company to ensure that the waste is removed responsibly.
All usable marijuana for sale in Washington
must carry a warning that discloses all
pesticides, herbicides, fungicides or other
compounds used for pest control or plant
disease in production or processing.
