Medical cannabis for migraines — patient guide in Puerto Rico

Why it may help

Migraine is increasingly understood as a disorder of how the brain processes pain and sensory signals, and the body's own endocannabinoid system plays a role in that regulation. This network of CB1 and CB2 receptors, along with natural compounds like anandamide, helps modulate neurotransmitter release, pain pathways in the trigeminal system, and inflammation. Some researchers have proposed that lower endocannabinoid activity may contribute to migraine, which is part of why the interaction between plant-derived cannabinoids and these receptors is being studied.

How patients use it

People who pursue medical cannabis for migraine are usually seeking relief from head pain, as well as the nausea and light or sound sensitivity that often come with an attack. By acting on the endocannabinoid receptors involved in pain signaling and inflammation, cannabinoids may help dampen some of these symptoms for certain patients. Research is exploring whether cannabis can reduce the intensity or frequency of attacks, but responses vary widely from person to person.

Strength of the evidence

The scientific evidence for cannabis in migraine is still limited and emerging, drawn largely from patient reports and small or preliminary studies rather than the large, rigorous trials that support cannabis for chronic pain or chemotherapy-induced nausea.
