Not an expert but I'm sure inhaling any kind of smoke is not good for the lungs but you don't smoke 20 Marijuana cigarettes a day like you would tobacco. It's not consumed in the same quantities. The biggest difference between the two are that the Tobacco companies add a lot of chemicals to their product that can cause cancer. I would think that Marijuana is organic.

I'm actively working on this. We've built lab equipment for academic researchers to run the ongoing study.

Further, second hand smoke from cannabis is worse than second hand smoke from tobacco!

>That's the most common way to consume cannabis.

I'm very suspicious of this claim for users in Colorado without a source. Anecdotally, the vast majority of legal use I see in Colorado is edibles. They don't have the stigma of smoking or the (legitimate) smoke inhalation concerns and thus seem much more popular among legal users.

Flower is around 60% market share. And it's usually smoked.

By comparison, edibles are around 7% market share.

Some of those flowers are also consumed using vaporizers or Volcano-type inhalers, which have no negative side-effects (since no carcinogens are generated). I doubt it's a high percentage though.

> have no negative side-effects

Do you know if this has been studied?

Perfect thank you.

I suspect you're right, but I believe (not a user myself) most users consume many fewer joints than cigarettes. I've known many "2 packs a day" tobacco users, but never someone who smokes so much weed. I'd guess that average marijuana users have similar lung issues to 'light' smokers.

On the other hand cigarettes have filters and to my (limited) knowledge no one smokes weed through a filter.

Whether filters are actually providing any health benefit or not is apparently a controversial topic

Lots of people smoke weed through a filter. That's the purpose of water in a bong.

This isn't really the same thing. Technically bongs, bubblers and bowls are much worse to smoke than a joint. Because these devices make it easier to "inhale the smoke", users typically get a far larger "hit" then they would from smoking a joint. This is much more damaging.

This is not accurate.

What about the ones smoking joints?

Sure. Visit Amsterdam, and you'll find most joints have filters. Of course, they aren't "proper" filters, just tubes of paper rolled up and placed in the smoking end.

They are not really supposed to be filters though, just 'roach' to make the joint easier to hold.

Yup. Doesn't really exist in american pot culture, though - from that point of view, it is a filter. I think some folks would call those rolled-up paper bits wussy or something. Then again, lots of folks here (Norway) smoke hand-rolled cigarettes without filters as well - mostly starts as a cost-saving thing and cops aren't going to give you crap for having drug paraphernalia because you have cigarette papers like they would in the states.

I can't remember if I've seen actual filters for sale in the shops in Amsterdam or not, but I'm going to guess they'd sell so long as they don't affect the buzz at all.

I think it's safe to say that lighting stuff on fire and inhaling the smoke is bad for you, regardless of the substance.

Note, I do smoke pot and cigars. I'm pretty sure both are bad for me.

I'm sure smoking anything is harmful to some extent, but tobacco is particular harmful. For instance, it causes mouth cancer just by chewing on it.

Ah, a man of sound first principles

That has been studied, of course. It's hard to believe most information about cannabis due to the decades of government-corporate propaganda against it.

Tobacco is highly toxic. Cannabis is not at all toxic, and in fact beneficial. That makes a difference in the smoke.

I read a report from the UK saying that cannabis's antioxidants and other helpful chemicals made up for any harm it caused by smoke.

One can vape anyway, and most serious enthusiasts dab.

Do you have any references handy? I would like to look at any studies you know of in that area.

If only my bookmarks were more organized... I'll check back if i can locate the articles i mentioned.
