Cannabis in Texas: Strict Laws, Arrest Risk & What Tourists Must Know

Texas is the second-largest US state by area and sits at the opposite end of the cannabis spectrum from Colorado or California. If you are travelling to Houston, Dallas, Austin, or San Antonio, you must be clear on this: cannabis is illegal in Texas, and the consequences can be serious.

This guide explains what is permitted, what is not, and why Texas maintains such a strict stance despite a nationwide trend towards legalisation.

The Law: Clear and Severe

Possession of under two ounces (56g) of cannabis in Texas is a Class B Misdemeanour — punishable by up to 180 days in gaol and a fine of up to 2,000 USD. This is no rare occurrence: Texas ranks among the states with the highest per-capita cannabis arrest rates in the US.

From two ounces to four pounds, the penalty rises to up to one year in custody and a 4,000 USD fine. Larger quantities can be charged as a felony, with sentencing ranging from two to 99 years.

For foreign nationals — including UK citizens — there is an additional risk: a cannabis arrest in the United States can result in a permanent ban on entry and visa complications for future travel.

Offences and Penalties in Texas

• Possession under 2 oz (56g): Class B Misdemeanour — up to 180 days + 2,000 USD
• Possession 2–4 oz: Class A Misdemeanour — up to 1 year + 4,000 USD
• Possession 4 oz to 5 lbs: State Jail Felony — 180 days to 2 years + 10,000 USD
• Possession over 5 lbs: Third Degree Felony — 2–10 years custody
• Sale of any quantity: Felony, up to 99 years for over 2,000 lbs
• Foreign nationals: Arrest may result in a permanent US entry ban

Compassionate Use Programme (CUP): The Restricted Medical Scheme

Texas does have a medical cannabis programme — the Compassionate Use Programme (CUP) — but it is one of the most restrictive in the United States. Qualifying conditions include epilepsy, terminal illness, PTSD, multiple sclerosis, Parkinson's disease, ALS, autism, and cancer. The maximum THC concentration in CUP products was recently raised to 1% — still extremely low compared with other states.

Foreign patients have no access to the CUP. The programme applies exclusively to Texas residents with a valid prescription from a registered CUP physician.

• CUP applies only to Texas residents — no tourists, no foreign nationals
• Qualifying conditions: epilepsy, PTSD, MS, Parkinson's, ALS, autism, cancer, terminal illness
• Maximum THC: 1% — far below other US medical programmes
• Only three state-licensed dispensing organisations in the entire state
• No flower sales permitted — oils, tinctures, and similar forms only

Dallas, Houston, Austin: Local Decriminalisation

Several major Texas cities have passed local decriminalisation policies. Dallas voted in November 2024 to end arrests for small quantities; Austin passed a similar initiative earlier. In practice, enforcement for small amounts has decreased in these cities. However — and this is critical — local policy does not override state law. Texas State Police and county sheriffs are not bound by city guidelines.

Why Does Texas Remain So Conservative?

The political arithmetic is straightforward: Texas is dominated by Republicans who are traditionally opposed to legalisation. Governor Greg Abbott and Attorney General Ken Paxton have repeatedly fought local decriminalisation efforts — most recently by suing cities that sought to restrict cannabis enforcement. A strong evangelical Christian base has also blocked every legalisation attempt to date.

Although polls show a majority of Texans support legalisation (Texas Monthly data), that is not yet enough for legislative action.

Texas vs Colorado: Legal Comparison

The Border State Warning: Cannabis Across State Lines

A particularly important warning: Texas borders Oklahoma (strict laws) to the north and New Mexico (legal) to the west. Anyone travelling from Colorado or New Mexico into Texas with cannabis commits a federal offence — Interstate Drug Trafficking — regardless of quantity. Interstate 70 and US-287 are actively monitored by law enforcement. No exceptions. Tourist status offers no protection.
