Yet by 1980 it was learned that smoking the drug came with the risk of damaging lungs and turning asthma into chronic bronchitis. So the risks of smoking it far outweighed the advantages.
I was a patient of National Jewish Health in 1985 and one of my fellow asthmatics had a problem with smoking the weed. In fact, it was such a problem at the time that the hospital made an effort to mention recent studies that mentioned that smoking cannabis can harm a young asthmatics lungs.

- b. use of marijuana can lead to unstable peak flows due to changes in theophylline metabolism
- c. studies show that marijuana usage can lead to adverse effects on short-and long-term memory function.
