American researchers reveal that taking marijuana in the form of a pill provided greater pain relief than when smoked.
Researchers at Columbia University in New York conducted their study on a group of 30 volunteers, 15 male and 15 female, all of whom were daily cannabis smokers. They were either allowed to smoke marijuana, consume it in form of a pill or take a placebo.
AdvertisementThey were asked to take part in a pain test, in which they immersed their hands in extremely cold water for up to two minutes and were asked about their sensation of pain.
The researchers found that both the groups, who either smoked marijuana or took it in form of tetrahydrocannabinol (THC) pills experienced lower pain though those who took THC pills reported long-lasting decreases in pain. The study has been published in journal Neuropsychopharmacology.
