This is a great start and raises a lot of questions, for example:

- 50 of 56 marijuana smokers in this study also used tobacco - how does this affect the results?

- How does frequency of use compare in the marijuana vs. tobacco cohort?

- How does smoking compare to vaping (both e-liquid for nicotine and thc, and dry herb for marijuana)?

- How would a filtered marijuana product affect these risks?

That first point alone makes me distrust this study. Why go with such a shitty design that you can’t really conclude anything meaningful? It’s not that hard to find marijuana smokers who don’t smoke tobacco, and then you could have told us something interesting.

Are you not always putting tobacco in it somehow ?

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.”

yeah—it leaves ambiguity around whether it’s marijuana, the combination of tobacco and marijuana, or something else

I believe that any smoke as a byproduct of combustion will do this. Even more so if that's the only thing you're breathing in for minutes at a time.

Just leaving this in as a reminder for anyone. It's not worth it. Don't smoke.

Nonetheless, the claims presented shouldn't be comparing both as independent from one another.

This is good advice. There are many vaporizers on the market. Nobody has a reason to combust and smoke anything in 2022.

no one has a reason to pop a wheelie on a bike, or do skateboard tricks, or wear stilettos, but some things just make you look cool!

One of these things is not like the others.

Yeah, this conclusion only really tells us anything if marijuana + tobacco smokers generally smoke less tobacco than tobacco only smokers. Otherwise it's no surprise that someone who smokes a pack a day and smokes marijuana is worse off than someone who just smokes a pack a day.

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.

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.

"we had a free afternoon so we evaluated a grand total of 80 x-rays with the statistics toolbox of stats 101".

Breathing smoke was never healthy. Eat your weed.

The only time I ended up in a hospital due to substances was because I thought I was dying after eating too much of an edible, even though it was really just my first, and only, panic attack. Be careful.

If Marijuana is a serious medicine, then I’d personally expect it to be packaged by professional laboratory in some sort of precisely dosed unit, and to only contain the compounds required to derive the therapeutic benefit.

The amateurness of it I can kinda get past, but I’ve never been able to take the idea of smoking your “medicine” seriously.

I stopped taking it in any form a few months ago, and stopped with Adderall too right before the shortage. Unless you have some kind of chronic pain or have cancer and it's marijuana vs opioids, it is more for personal entertainment than anything else. California confirmed it as more of a means of entertainment similar to, but still possibly less dangerous than, alcohol by making it legal for retail sale on the state level a few years back.

that's not how the propositions work in california though. it's proposed, backed by enough of the citizens via signatures, then voted on in a simple majority passage during an election. There is no "confirmation" one way or the other of it being anything other than something that a majority of the voters in california wanting to do it recreationally.

Search for videos of multiple sclerosis patients using cannabis and you will understand.

Whatever efficacy it has, it doesn’t rely on being smoked. A delivery method that’s obviously a massive health risk.

You are correct. However, MS typically comes with spasticity and trouble swallowing: the former prevents operating a device with small parts, and the latter prevents effective oral delivery. A pipe is comparatively easy to use when your hands and legs don’t want to stay in any position.

If somebody’s incapable of swallowing foods or liquids, then they’re going to have somebody caring for them who can administer medicines. The suggestion that MS patients HAVE TO smoke their medicine is really some of the funniest stoner logic I’ve ever heard. If you really think they have to breath it in though, there’s already an actual delivery system to accomodate that, it’s called a nebulizer.

No, it’s called a vaporizer. There are some which are certified medical devices, such as the Volcano.

Do you think this guy is acting?

The FDA hasn’t approved any dry herb vaporizers for any form of medical use at all. If you want to inhale a liquid medicine, then you do it with a nebulizer. The reason for this is that it’s obviously stupid to inhale all the toxic and carcinogenic substances you get from smoking or vaping marijuana.

You can continue making comments about efficacy if you like, but I don’t know who you’re addressing them to, because I haven’t said anything about efficacy at all.

Heh, it’s like the US is the king of the world and FDA the official global authority. You realize there are hundreds of other countries, federations and unions with their own administrations?

Definitely. Alongside the push for legalization we should also be pushing for more edibles and vaporization and less combustion. Inhaling burnt anything is terrible for you.

I believe there's been studies showing that people with fireplaces in their homes have meaningfully lower life expectancy than those with other forms of heating too.

Vaporization ain't that great either.

Elaborate?

You're still exposing your lungs to unnecessary large volumes of chemicals just to keep nicotine withdrawal at bay.

Why should you push for legalization?

Because weed (ideally not smoked) is no more harmful than alcohol and prohibition is counter-productive.

I don't see how "not being more harmful than alcohol" is a reason.

To starve the industrial prison complex.

Dosage is a lot more variable in edibles. Numerous people I know have had bad trips due to the unknown dosage in edibles.

It's not fun. We need proper regulations to label dosages and control production.

What kind of FUD shilling is going on this thread?

All legitimate dispensaries are required by law to only sell products that have been accurately labeled with respect to their content.

Please take your outrage to a more appropriate social media site.

Regulations vary wildly by state and I don't live in one with such regulations. Moreover, labeling only works if the gov't is spot testing and inspecting production facilities.

Right, I forgot the US is a backwards country where the people worship corporate profits.

In the state I live in, as well as in neighboring states, there are laws that require producers of marijuana to include test results showing the breakdowns of compounds found in the tested samples. I don't know how strict the laws are, but based on the several pages of data that dispensaries are required to adhere to the sold product, I'd imagine that the laws are pretty strict.

That said, there's so much that can impact someone's perception of dosage with edibles. The mix of CBD/THC/CBN, what someone ate prior to consuming the edibles, how much time has passed between eating a meal and consuming the edibles, and things like metabolism and liver function all factor in.

Said another way: the effectiveness or perceived potency of marijuana, even with perfectly consistent and controlled dosages, can depend on so many other factors than consistent and controlled dosages.

pick your vice .... they all have a cost.... booze, cigs, dope, overeating, nothing is free :))))))

And yet many people avoid all those vices you mention.

ah based on obesity rates and failures of basic drug tests I would respectfully disagree...

Note that “many” doesn’t mean “all”.

And expand your horizons outside of one country as the US doesn’t represent all of the human race. The epidemic of obesity and diabetes is mostly an American phenomenon.

might want to read the above article.... I don't disagree with you BTW.... Have a nice day

That list appears to support what I said. The United States is way ahead in obesity rates, compared to other western nations.
