Marijuana More Harmful Than Cigarettes According To Research Study

August 3rd, 2007 · No Comments

A recent research report published in Thorax – An International Journal of Respiratory Medicine, stated that “one cannabis joint causes a similar degree of lung damage as between 2.5 and five tobacco cigarettes“.

The three year study by New Zealand’s Medical Research Institute ( found that longtime pot smokers can develop symptoms of asthma and bronchitis, along with obstruction of the large airways and excessive lung inflation.

Marijuana smokers had symptoms that included wheezing, coughing, chest tightness and phlegm – all of which were associated with tobacco smokers, except chest tightness.

Participants were recruited into four groups: cannabis only, tobacco only, combined cannabis and tobacco, and non-smokers of either substance.

The study, which used lung function tests, high-resolution X-rays and questionnaires, also revealed that among marijuana smokers damage occurred to the small, fine airways which are important for taking in oxygen and removing waste gases. The extent of damage rose in proportion to the number of joints smoked.

Hospital specialists state that they are seeing an increasing number of people with emphysema specifically related to marijuana smoking.
