Asthma & Medical Marijuana

Asthma is a common chronic inflammatory disease of the respiratory system typified by airflow obstruction and bronchospasm. Symptoms include shortness of breath, wheezing, coughing, and chest tightness.

Genetic and environmental factors are thought to play the major role in the cause of Asthma. Diagnosis is usually based on the pattern of symptoms and the response to therapy.


"Asthma doesn't seem to bother me any more unless I'm around cigars or dogs. The thing that would bother me most would be a dog smoking a cigar."

-- Steve Allen, Comedian

Medical Marijuana and Asthma

Marijuana has long been a folk remedy used to ease the symptoms of Asthma. Recently, research is beginning to find out, how and why it works..

Researchers have found the Medical Cannabis and its constituents, Cannabinoids appear to unblock airways in a similar fashion to some pharmaceutical drugs, but with different side effects.  An examination of human lung tissue revealed that THC can block muscle contractions by reducing the activity of an overactive signaling molecule (acetylcholine).


“It (THC) also succeeded in reversing experimentally induced asthma, in a manner that was comparable to what could be achieved with a standard therapeutic bronchodilator that was widely used at the time.”

-- Dr. Donald Tashkin, UCLA
