A Missouri lawmaker has introduced a proposed constitutional amendment that would significantly rewrite the state’s marijuana and hemp laws.
If passed, the proposal would expand legal protections, remove possession limits, and reshape how marijuana is regulated, taxed, and enforced across Missouri.
House Joint Resolution 106 would repeal the state’s existing constitutional provisions on marijuana and replace them with a new framework that covers both medical and recreational cannabis.
Under the proposal, statewide purchase and possession limits would be eliminated, adults and qualifying patients could grow marijuana at home, and legal protections would expand for consumers, caregivers, and businesses involved in cannabis-related activity.
The resolution also calls for expunging certain nonviolent marijuana-related convictions and limiting civil and criminal penalties tied to lawful use.
It includes workplace protections that would prohibit discrimination for off-duty cannabis use, unless impairment affects job performance or safety.
If lawmakers approve it, the proposal would go before Missouri voters in the November 2026 general election.
The measure directs the General Assembly to establish a regulatory and tax structure for marijuana and hemp products, with limits on combined state and local taxes.
Revenue would be dedicated to veterans’ services, substance abuse treatment, and public defender programs.
For now, the measure has been introduced but hasn’t been debated or approved by either chamber of the Missouri General Assembly.
No hearings have been scheduled yet.
