The Future of Specialty Drugs: A Policy Discussion on Treatments & Affordability.

The development of specialty drugs has had a profound effect on treating patients suffering from chronic conditions, but these treatments come at a high cost to consumers and drug companies alike.

join The Hill & the USC Schaeffer Center for a policy forum on how to make these promising new treatments more accessible and affordable for patients who need them most, while improving the quality of care they receive. 

why marijuana’s main ingredient might help patients breathe easier.

Published last week in the British Journal of Pharmacology, a new study shows marijuana may have a similar effect on the airways as some asthma medications.

Using samples of human lung tissue, French researchers found that THC could block muscle contractions caused by a signaling molecule called acetycholine.

Acetycholine is responsible for maintaining muscle tone of the airways and also contributes to contractions in asthma attacks. Interestingly, asthma medications block the same molecule, but from a slightly different angle.


Does the idea of using medical marijuana to treat asthma symptoms leave you scratching your head? Due to the fact that the most popular method of recreationally consuming cannabis is smoking, it may seem like an unlikely medical treatment for a respiratory condition. Any doctor will tell you that smoking cigarettes is not a good idea for asthma sufferers (or for anyone, really), but evidence is showing that cannabis may have beneficial effects for those with asthma or other respiratory conditions—even when smoked.

Cannabis Smoke May Benefit Asthma and Lung Functions.

The unique nature of cannabis is demonstrated partly by the special characteristics of its smoke. Unlike virtually all other forms of smoke, which impair lung function, cannabis smoke may actually improve it.

That being said, vaporizing cannabis is clearly the superior alternative to smoking cannabis, as it provides the medicinal compounds of marijuana without the negative side effects of smoke (such as carcinogens and other cancer-causing chemicals).

Top 6 benefits of cannabis for asthma

Asthma is a chronic respiratory disease that currently affects up to 300 million people worldwide, and was responsible for approximately 250,000 deaths in 2011. Cannabis has been used as a means of treating the symptoms of asthma for millennia, in various medicinal traditions including those of ancient India and China.

Effects of Smoked Marijuana in Experimentally Induced Asthma. AMERICAN REVIEW OF RESPIRATORY DISEASE, VOLUME 112, 1975.

Recent studies have demonstrated significant, acute bronchodilatation in healthy young men after both smoked marijuana (1, 2) and oral Delta 9-tetrahydrocannabinol (Delta 9-THC), the principal psychoactive ingredient in marijuana (2). More recently, the smoking of marijuana and ingestion of Delta 9-THC by subjects with chronic, clinically stable, bronchial asthma of minimal to moderate severity has been shown to produce airway dilatation of a magnitude similar to that previously noted in healthy subjects (3).
