“As a physician treating headache patients for a number of years, I have seen no one who has reported a sustained headache benefit from using marijuana.
There have also been reports of marijuana being associated with increased headache. One study suggested that migraine sufferers usually develop tension-type headache after chronic use.
The potential intoxicating effect, possible long-term harm with frequent use, and the social stigma associated with this herb are likely to restrict its medicinal use for headache conditions.”
