HB 1763 repeals and amends multiple provisions across the Texas Agriculture Code, Health and Safety Code, Penal Code, Family Code, and Education Code to effectively decriminalize marijuana and cannabis-related offenses. It removes penalties for possession, use, sale, and transportation of marijuana, cannabinoids, synthetic cannabinoids, and related paraphernalia. Additionally, the bill eliminates criminal consequences tied to these substances in contexts such as educational disciplinary actions, community supervision, and family law. Provisions regulating controlled substances are adjusted to exclude marijuana, and various statutes are revised to reflect the removal of marijuana-related offenses. The changes include repealing existing regulatory frameworks and criminal penalties associated with marijuana, while amending procedures for testing, prosecution, and penalties under related laws.
