The City of Berkeley strongly encourages all qualified patients, primary caregivers, and medical cannabis collectives to consult the available cannabis cultivation literature to ensure that the medical cannabis lawfully cultivated under state law is free of undesired toxins or molds. The City of Berkeley cautions that natural molding from improper storage, certain soils for indoor growing, foreign materials that unintentionally becomes lodged in cultivated cannabis, and pesticides, can all potentially render the medical cannabis totally unsafe for consumption. Collectives are encouraged to use their best effort to determine whether or not cannabis is organically grown. (Ord. 7068-NS § 3 (part), 2008: Ord. 6620-NS § 1, 2001)
