Adult-use cannabis is fully illegal in Iowa. Iowa has no decriminalisation law and has not advanced adult-use legislation.
Differences from Medical Use
- Medical allows ≤3% THC CBD only; adult-use of any cannabis product illegal
- No purchase limits relevant — adult-use has no legal pathway
- No tax framework exists for adult-use cannabis
Local Ordinances
- No Iowa municipalities have decriminalised cannabis
- Iowa City and other college towns have seen advocacy for decriminalisation but no enacted ordinances
- Legislative outlook: incremental medical expansion possible but adult-use unlikely short-term
