“Sativex® is an exclusive cannabinoid-based drug approved for the treatment of spasticity due to Multiple Sclerosis (MS).

The most common side effects include dizziness, nausea, and somnolence. However, it is still under debate whether the drug could cause negative cognitive effects.

The aim of our study was to investigate the effect of Sativex® on functional and psychological status in cannabis-naïve MS patients.

After the treatment, we did not observe any significant neurobehavioral impairment in all the patients, but one.

Our findings suggest that Sativex® treatment does not significantly affect the cognitive and neurobehavioral functions.”
