Full Breakdown

Texas Health and Safety Code Chapter 481 prohibits cultivation of marijuana (cannabis with over 0.3% THC) by individuals. Growing any amount is a felony offense. Possession of 4 ounces or less is a Class B misdemeanor (up to 180 days jail, $2,000 fine), but cultivation is charged more severely based on weight. Harris County has no local authority to permit home cultivation. The Compassionate Use Program (TCUP) allows only licensed dispensing organizations to cultivate low-THC cannabis (1% or less THC). Hemp (under 0.3% THC) cultivation requires a USDA-compliant state license.
