Iowa Bans Home Cannabis Cultivation Under Code 124E and 124

Iowa has not legalized recreational marijuana, and Iowa Code 124E (the Medical Cannabidiol Act) limits manufacturing, cultivating, harvesting, and processing of medical cannabidiol to enclosed, locked facilities operated by state-licensed manufacturers. Patients buy products only at licensed dispensaries, with THC capped at limited amounts per 90 days and smokable flower prohibited. Outside that program, Iowa Code 124.401 makes cannabis cultivation a controlled substance offense punishable as a felony based on quantity. There is no statutory authority for any city or county to allow personal cultivation, so home growing is preempted statewide.

Home cultivation, even by a medical cannabidiol cardholder, can be charged under Iowa Code 124.401 as a class D felony or higher depending on plant count and weight, plus civil forfeiture and federal exposure.
