This is a great start and raises a lot of questions, for example:<p>- 50 of 56 marijuana smokers in this study also used tobacco - how does this affect the results?<p>- How does frequency of use compare in the marijuana vs. tobacco cohort?<p>- How does smoking compare to vaping (both e-liquid for nicotine and thc, and dry herb for marijuana)?<p>- How would a filtered marijuana product affect these risks?
Conclusion: “Airway inflammation and emphysema were more common in marijuana smokers than in nonsmokers and tobacco-only smokers, although variable interobserver agreement and concomitant cigarette smoking among the marijuana-smoking cohort limits our ability to draw strong conclusions.”
I'm curious is they are comparing marijuana in states where recreational cartels have taken over or if they are doing much to check the quality of the content.<p>I've noticed almost all recreational marijuana now is just bad. Like it will hurt your lungs and is sprayed throughout the grow with lots of pesticides bad. There are a lot of factors, from mineral buildup to curing conditions that could all have to do with the impact on health.
