Full Breakdown

Texas Health and Safety Code Chapter 481 criminalizes the cultivation of marijuana statewide. Bexar County has no local exemption and no homegrow allowance for medical patients enrolled in the Compassionate Use Program. Even one plant can support a felony charge depending on aggregate weight. Bexar County Sheriffs Office and San Antonio Police enforce state drug law in their respective jurisdictions, with prosecution by the Bexar County District Attorney. Hemp plants under 0.3 percent delta-9 THC are legal only when grown under a Texas Department of Agriculture license. Hobby hemp cultivation without a license is also unlawful. Local decriminalization measures cannot override state cultivation crimes.

Violations & Fines

Growing marijuana in Bexar County exposes residents to state felony or misdemeanor charges under TX HSC Chapter 481 depending on plant count and weight, plus potential property forfeiture.

Frequently Asked Questions

Can a Compassionate Use patient grow plants at home?
No. Texas medical cannabis patients must obtain prescribed low-THC products from licensed dispensing organizations. Home cultivation remains a state crime, even for enrolled patients.
Is one marijuana plant a misdemeanor in Bexar County?
Charges depend on aggregate plant weight, not plant count. Even small grows can support felony charges under Texas drug law, and prosecutors retain discretion under cite-and-release programs.
