Cannabis Laws in Iowa
Is weed legal in Iowa? Medical only — cannabis is legal for registered medical patients, but not for general adult use.
Iowa's medical cannabis program serves registered patients through licensed dispensaries. The default purchase allowance is 4.5 g THC per 90 days; a qualifying practitioner waiver can authorize more. This is a purchase allowance, not a product concentration cap. Raw flower for smoking and smoking medical cannabis are prohibited.
Federally, cannabis is still a controlled substance nationwide — but that status is in flux. See where rescheduling stands →
Regulated by Iowa HHS, Office of Medical Cannabidiol.
