Is RSO Legal in Texas?

What is RSO?

Rick Simpson Oil (RSO) is a cannabis extract that contains very high levels of THC and other natural compounds from the plant. It was first developed by Rick Simpson, a Canadian medical cannabis advocate who used the extract to treat his skin cancer, and then later shared his story around the world.

Unlike many other concentrates, RSO is a full-spectrum extract, meaning it keeps all the cannabinoids, terpenes, and other compounds naturally found in cannabis, maximizing the potential therapeutic effects you receive.

Because of its high THC concentration, RSO is known for its potent psychoactive effects and is often used for medicinal purposes, especially for cancer treatment and symptom relief.

Is RSO Legal in Texas?

In Texas, RSO is only legal for patients who are part of the state’s medical cannabis program. 

If you’re enrolled in the Texas Compassionate Use Program, you can get RSO with a prescription from a licensed physician. 

You can also buy RSO online through our website without a medical card; we’ll deliver it to your doorstep discretely. 

Recreational cannabis isn’t legal in Texas, so high-THC RSO isn’t available outside the medical system or select sources like us. However, there are brands that offer hemp-derived RSO alternatives with less than 0.3% THC that you can order online anywhere in the state.

Will RSO Show Up on a Drug Test?

Yes, it will. Since RSO contains high amounts of THC, it’s almost certain to show up on a drug test. If you’re not enrolled in the medical program, that could lead to legal or workplace issues. 

Even for registered patients, THC from RSO will appear just like any other cannabis product, so it’s best to plan ahead if testing is a concern.

Where to Buy Legal RSO Products in Texas

If you’re in Texas and want to explore RSO safely and legally, here’s where you can start:

• Online at RickSimpsonOil.com: As the official RSO website, we are the most reliable place to buy authentic Rick Simpson Oil. You can shop our full line of products from RSO syringes, tinctures, gummies, and more, all backed by third-party lab testing. 
• Licensed Dispensaries: If you’re part of the Texas Compassionate Use Program, you can buy RSO through approved dispensaries with your medical prescription.
• Medical Cannabis Programs: Because Texas allows medical marijuana for specific conditions like cancer, epilepsy, and PTSD, registered patients can legally purchase RSO through state-approved medical channels.
• Delivery Services & Local Retailers: Some stores sell hemp-based oils marketed as “RSO-style” products. These contain less than 0.3% THC and are not the same as true high-THC Rick Simpson Oil, so always check lab results before buying to know exactly what you’re getting.
