Medical New marijuana study on long term lung function

Click For Summary
SUMMARY

The recent study titled "Association Between Marijuana Exposure and Pulmonary Function Over 20 Years" published in JAMA concludes that smoking 1-2 joints per week does not adversely affect long-term lung function. The study's co-author, Dr. Stefan Kertesz, suggests that the deep inhalation technique used by marijuana smokers may contribute positively to lung health. However, the study has been criticized for its narrow focus on forced expiratory volume (FEV1) and forced vital capacity (FVC) without addressing potential links to lung cancer or other respiratory issues. Critics argue that the findings should be interpreted with caution, as they do not encompass all relevant health outcomes associated with marijuana use.

PREREQUISITES
  • Understanding of pulmonary function metrics such as FEV1 and FVC
  • Familiarity with marijuana consumption methods and their physiological effects
  • Knowledge of the long-term health implications of smoking
  • Awareness of the differences between marijuana and tobacco smoking
NEXT STEPS
  • Research the long-term effects of marijuana smoking on lung cancer rates
  • Explore the physiological differences in inhalation techniques between marijuana and tobacco users
  • Investigate the role of deep breathing in lung health among marijuana smokers
  • Examine other studies that analyze the broader health impacts of marijuana use beyond lung function
USEFUL FOR

Healthcare professionals, researchers in pulmonary medicine, and individuals interested in the health effects of marijuana use will benefit from this discussion.

Since you're targeting the smoke point of THC and not burning the cellulose (there's still a bud leftover after you vaporize it) you have to be careful about what you extrapolate from a cigarette study (which doesn't have THC and which does burn cellulose). I don't know any numbers.

I've never even seen a vaporizer before so I'm not expert on the smoke it contains. A internet picture is the best I can do. I would assume the density of smoke correlates with it's carcinogenicity so I need to see the smoke you're talking about.

The theory of the bong is that the water filters it, but the water doesn't actually filter everything. As bubbles pass through the water, only the contents on the edge of the bubbles get held behind, so it's actually quite a crude filter. If you have a way to percolate the bubbles and diffuse them more, then you are getting a better filter.

Right, surface area is much higher with smaller bubbles, and surface area matters most in this case. I think the only point of a gravity bong is to allow the smoke to cool.

How about rectal administration haha (from pdf above):

3.1.4 Rectal Administration
With rectal application, systemic bioavailability strongly differed depending on suppository formulations. Among formulations containing several polar esters of THC in various suppository bases, THC-hemisuccinate in Witepsol H15 showed the highest bioavailability in monkeys and was calcu-lated to be 13.5%.[50] The rectal bioavailability of this formulation was calculated to be about as twice as high as oral bioavailability in a small clinical study.[25]

I don't know why they would use monkeys - I have several friends who would have volunteered after wasting their last 5 bucks on a cannoli and scratch and sniff stickers.

haha, wow, who'd have thought... now they just need to come out with cannabis toilet paper.
