Frequently asked questions Why Does Texas Have Medical Marijuana Prescriptions? As cannabis is federally illegal, medical marijuana doctors in other states “recommend” or “certify” cannabis for their patients. Prescription is not technically legal. Texas, being the Lone Star State, does things a little differently. Doctors’ medical marijuana recommendations/certificates are called “prescriptions”, and patients don’t actually receive any certificates, recommendations or MMJ cards. Instead, the patient is registered onto the Compassionate Use Registry of Texas (CURT) during the physician’s evaluation if they qualify. Why this is, we here at Leafwell cannot say for sure. However, as cannabis prescriptions are technically illegal, it would be reasonable to assume this is a) due to the low amount of THC in medical marijuana products in Texas, and b) Texas trying to set a precedent of sorts.
