Lewisville, TX Cannabis Regulations: Home Cultivation (2026)

Texas Health and Safety Code Chapter 481 classifies marijuana as a Schedule I controlled substance. Home cultivation of cannabis is illegal in Lewisville and all of Texas with no exception for personal use, medical use, or any quantity. Cultivation of any number of cannabis plants is treated as manufacturing or delivery of a controlled substance under Health and Safety Code Section 481.113, which is a felony offense. Possession of marijuana remains criminal in Texas, with penalties based on weight: under 2 ounces is a Class B misdemeanor, 2 to 4 ounces is a Class A misdemeanor, and amounts over 4 ounces are felonies. Denton County prosecutors generally follow state sentencing guidelines. The Texas Compassionate Use Act allows registered dispensing organizations to produce low-THC cannabis (no more than 1% THC by weight) for patients with qualifying conditions including epilepsy, seizure disorders, multiple sclerosis, spasticity, amyotrophic lateral sclerosis, autism, terminal cancer, and incurable neurodegenerative disease. However, patients may not grow their own cannabis plants. All low-THC cannabis must be obtained through one of the state-licensed dispensing organizations. As of 2024, no licensed dispensaries are located in Denton County. Contact the Lewisville Police Department at (972) 219-3610 for questions about controlled substance enforcement.
