A new placebo-controlled trial presented at the American Headache Society reveals that vaporized cannabis—especially a combination of THC and CBD—offers significant relief for migraine sufferers. In the study, over two-thirds of participants reported pain relief two hours after using either THC (68.9%) or a THC–CBD combination (67.2%), while only 46.6% experienced relief with a placebo. The combined THC–CBD group also showed marked improvements in sensitivity to light and sound. Additionally, 34.5% of those taking the combination achieved complete pain relief, doubling the rate seen with placebo.

While the study reported no serious adverse events, some users did experience mild cognitive impairment, particularly with THC-containing products. These findings signal a promising alternative for migraine management and reinforce the growing scientific interest in medical cannabis. Read the full report at Marijuana Moment.
