MO HB1287

Establishes an excise tax on unauthorized substances (controlled substances and illicit alcoholic beverages) possessed by dealers, with varying rates based on substance type and quantity.

Tax rates include $0.40 per gram for separated marijuana stems, $3.50 per gram for other marijuana, $350 per marijuana plant with foliation, $50 per gram for cocaine, and $200 per gram for other controlled substances sold by weight.

Requires law enforcement agencies to report seized unstamped unauthorized substances to the Department of Revenue within 48 hours, and dealers must pay taxes within 48 hours of acquiring nontax-paid substances.

Creates the State Unauthorized Substances Tax Fund to receive tax proceeds, which are distributed as follows: 20% to Department of Revenue for collection costs, 10% to Department of Health and Senior Services for drug treatment programs, and 70% to Department of Public Safety for multijurisdictional drug enforcement.

Provides that tax payment information is confidential and cannot be used in criminal prosecutions, and establishes an Unauthorized Substance Tax Commission to review tax rates and recommend increases to the general assembly.
