Canada,
Colorado,

Oklahoma for the production of medical and
recreational cannabis. In 2014, a Canadian news investigation by
The Globe and Mail reported the discovery of myclobutanil in
medical cannabis produced by at least one government licensed grower. In September 2019,
NBC News commissioned

THC cartridges for
heavy metals, pesticides, and residual solvents like
Vitamin E; pesticides, including myclobutanil, was found in products from unlicensed dealers. In Michigan, the current state action limit for myclobutanil is 200
ppb in cannabis products. ==References==
