Why is tobacco demonized and marijuana commercialized?

Because mass produced tobacco products are conclusively correlated with an increased risk of developing cancers and cannabis is not.

surely is, too

the report stated pretty definitively there is no evidence showing that MJ leads to lung cancer, or other cancers in a statistically significant way, with the exception of a single type of prostate cancer which is easily cured.

It might have something to do with this...

>Regarding the link between marijuana and cancer, the committee found evidence that suggests smoking cannabis does not increase the risk for cancers often associated with tobacco use – such as lung and head and neck cancers. The committee also found limited evidence that cannabis use is associated with one sub-type of testicular cancer and insufficient evidence that cannabis use by a mother or father during pregnancy leads to a greater risk of cancers in the child.

Report shows that cannabis is not safe either. Increased mental disorders, possible link to coronary artery disease, bronchitis, etc

Nothing is safe, >Acetaminophen overdose is actually the leading cause for calls to Poison Control Centers across the US—more than 100,000 instances per year—and, each year, is responsible for: More than 56,000 emergency room visits. 2,600 hospitalizations. An estimated 458 deaths due to acute liver failure.

Yes, there may be an extremely small correlation with marijuana use and a few mental disorders, but the studies themselves are rather lacking in materiality. I personally know three schizophrenics two from the same family and another friend, all had the disease manifest well before any drug use.

Your possible and et ceteras are quite weak, especially considering the other possible factors for those diseases and the lack of any hard findings. Funny how tylenol and twinkies lead to more detrimental health effects while showing very little benefit to society

It is possible that schizophrenics and similar disorders naturally gravitate to cannabis to lessen their symptoms.

if the schizophrenia is latent prior to consumption, then by definition there can't be no effect. OTOH, if the choice to use drugs is induced or fueled by a mental disorder, that doesn't count in its favour in my book.

How empathetic of you. So any substance which eases crushing symptoms of a mental disorder is a crutch to you? Glad you're Ok.

No, it means that an apparent perception of easing symptons might just as well be another symptom. I don't think the claim you defended is verified, and OTOH cannabis use is linked to activating (or what's the word) latent schizophrenia, so it seems unreasonable to expect it could aliviate the condition.

A crutch? Wouldn't that be rather positive?

> an apparent perception of easing symptons might just as well be another symptom

Placebo effects are not exclusive to those with mental illness

It shows it's not safe, but it's harm is well within acceptable limits. Frankly, you'd have a hard time finding a natural product which was, on balance, as safe as cannabis when smoked.

Because that's exactly what should happen.

assuming that you aren't trolling with this....

> Why is tobacco demonized

Because Tobacco smoke is made up of more than 7,000 chemicals, including over 70 known to cause cancer (carcinogens).

How many chemicals make up marijuana smoke? Are any of them carcinogenic?

Do keep in mind that smoking is probably the most harmful of the many common ways marijuana is consumed. Vaporizing or eating cannabis renders zero carcinogenic chemicals from smoke.

For sure. Also smoking is the most obnoxious and invasive to the people around you.

Did you read the article?

Yup. It doesn't address the question of how many chemicals are in cannabis smoke, and how many of those are cancer-causing. That's a distinct question from "does smoking cannabis cause cancer." Aspartame is a carcinogen but Diet Coke does not cause cancer.
