1. I guess if it may

it may not too.

5. A few things come to mind

The first is in how often and in what quantities each are smoked. A cigarette smoker can be smoking dozens of cigarettes every day, year after year. Finding a comparable consumer of marijuana would be difficult. The second is how the hoi polloi accept exceptions to be the norm; suddenly we live in fear of smoking a joint, thanks to the WSJ.

7. Yep, Rupert's pukes like the meanness from liquor.

They could all use a joint.

2. Not surprising

I think long been suspected in some medical circles. It has more oil content than tobacco.

3. The science with references... This MD reads all the med science and comments...

The key takeaways:
At least 33 carcinogens are in marijuana smoke, including polycyclic aromatic hydrocarbons that are also found in grilled meat.

Most cigarette users inhale more smoke each day than do marijuana smokers, but cannabis users may inhale more deeply and hold in smoke longer, which can result in depositing four times more tar into their lungs.

When cigarette use was accounted for, no increased cancer risk was found and the same was found for head and neck cancer.

Regular marijuana use leads to symptoms of chronic bronchitis, but there is no evidence of emphysema (long-term lung damage) or increased risk of lung cancer.

Smoking one joint a day for ten years may only translate to six months of smoking a pack of cigarettes a day, and, in most studies on tobacco smoke and lung cancer, six months of smoking in a lifetime may even classify you as a “never smoker.”

4. Seems reasonable that anything you breathe into your lungs that isn't fresh air is harmful .

[Rebl2]

11. Agreed

[multigraincracker]

6. Chronic vs casual use.

IF you are smoking 4 or 5 joints a day, you have a problem. If you can't go a day or two without, you have a problem.
The good news is there is help with both cigarettes and pot. Just have to ask.

8. In my 50 odd years of smoking pot

No one I know has any long term medical problem from pot.

Not saying the science is wrong. Just not in my experience. Also, in my 50 odd years I’ve been told by other science reports that pot was going to cause such problems. Yet, no one I know.

9. My 55 years reflect the same experience.

I vape dried flowers, no combustion.

10. Same time frame, similar experience. I realize this is personal observation, not scientific proof,

12. More are waking up to the idea you do not have to SMOKE to benefit.
