How Cannabis Consumption Affects Asthma

Asthma afflicts an estimated 25 million people in America alone. That means that one out of every 13 people in America struggles with asthma, an ailment that cannot be cured, only controlled. This is a tremendous weight on the medical industry and one that medical professionals are always working to find new and improved treatments for.

A recent study published in BMC Pulmonary Medicine took 2,602 young adults in Norway who suffer from bronchial asthma and examined them for 13 years. They accounted for the asthmatic’s gender, age, years of education, body mass, earlier self-reported asthma and allergies, current tobacco smoking and cannabis smoking.

What they found was that for those with bronchial asthma inhaling smoke of any kind, both tobacco and cannabis, should be avoided. However, THC does act as a bronchodilator so administering medicinal cannabis through other means could be a highly beneficial way of opening irritated or inflamed airways.
