How Cannabis Treats Asthma By Rachel Garland 22.11.16 Experiencing coughing, shortness of breath, and chest tightness? It is estimated that one out of twelve people suffer from asthma – a chronic respiratory disease which typically becomes present during childhood. While many people experience minimal symptoms with treatment, asthma was linked to over 3,000 deaths in 2010 alone. Naturally, many asthmatics choose to stay away from cannabis for fear of exacerbating their symptoms. But contrary to popular belief, studies have shown cannabis has little to no long-term impact on the lungs. In fact – recent research is showing cannabis is helpful rather than harmful for asthma patients. Cannabis opens rather than restricts the airways Essentially, cannabis acts a bronchodilator rather than a Broncho constrictor. A study in the Journal of Pharmacology and Experimental Therapeutics showed that cannabinoids protect the lungs. Surprisingly, the study reve aled that THC and THC-V were the only cannabinoids to inhibit constriction, with THC being the most- effective. The results from this study are astonishing considering that bronchoconstriction is one of the biggest problem plaguing asthma sufferers. During an asthma attack, the bronchioles (air passageways in the nose and mouth) become constricted. As a result, the rate of oxygen flow is severely restricted. Cannabis helps to open up these airways. Several studies have shown that cannabis improves bronchoconstriction while resting and during an asthma attack. “THC is actually a very potent bronchodilator and that’s exactly what we need when we’re treating asthma,” “When we are suffering from an asthma attack, those bronchioles are squeezing on themselves, making it very hard to breathe. Well, enter THC. It opens those bronchioles right up and we can breathe better.” Cannabis possesses powerful anti- inflammatory effects. These mushroom-shaped crystals are the trichomes, which contain most of the plant's active cannabinoids. Asthma is a chronic inflammatory disease affecting the lungs’ airways. Essentially, this inflammation of the air passages causes a temporary narrowing of the lungs, which reduces the amount of oxygen carried throughout the body. For asthma sufferers, this makes breathing difficult, to say the least. In fact, inflammation is not only present during an asthma attack but also when resting. Low-level inflammation can also be found in bronchi and bronchioles of asthma sufferers. And when an asthma attack does occur, inflammation increases further. In severe cases inflammation can even cause total loss of breath. Cannabis is a well-known anti-inflammatory, interacting with cannabinoid receptors throughout the body, including the lungs. A study in the journal Mediators of Inflammation revealed that the cannabinoid CBD contains potent immunosuppressive and anti-inflammatory responses.
