Tourette syndrome is a disorder of the nervous system. If you have Tourette syndrome, you make unusual movements or sounds, called tics. You have little or no control over them. Common tics are throat-clearing and blinking. You may repeat words, spin, or, rarely, blurt out swear words.

Recent years have brought a wealth of new scientific understanding regarding how medical marijuana or cannabis can be beneficial for treating Tourette syndrome.

Tourette syndrome often occurs with other problems, such as:

Attention deficit hyperactivity disorder (ADHD)

Obsessive-compulsive disorder (OCD)



Tics typically show up between ages 2 and 15, with the average being around 6 years of age. Males are about three to four times more likely than females to develop Tourette syndrome.

The cause of Tourette syndrome is unknown. It is more common in boys than girls. The tics usually start in childhood and may be worst in the early teens. Many people eventually outgrow them.

No treatment is needed unless the tics interfere with everyday life. Excitement or worry can make tics worse. Calm, focused activities may make them better. Medicines and talk therapy may also help.

Medical Marijuana Efficiency

Reports have suggested that Cannabinoids can be used to reduce symptoms of Tourette’s syndrome.

Two different clinical studies were conducted in 2002. One study involved giving twelve Tourette’s patients one dose of THC, and then after two weeks given a placebo. 75% of this study’s participants reported feeling positive effects from the cannabis.

The second study was a randomized trial of twenty-four participants, all of whom were affected by tics from Tourette syndrome. The study reported that delta-9-tetrahydrocannabinol (THC), the primary psychoactive chemical in marijuana, reduces tics in Tourette’s patients.

In both these reports no serious adverse effects were reported.
