That’s correct. Weed is worse.

>Beyond just what's in the smoke alone, marijuana is typically smoked differently than tobacco. Marijuana smokers tend to inhale more deeply and hold their breath longer than cigarette smokers, which leads to a greater exposure per breath to tar.

Cigarette smoke isn’t magically bad because it’s cigarettes. ANY smoke tends to be bad. Smoking anything is like voluntarily exposing yourself to extreme air pollution.

Marijuana lovers go to a lot of lengths to rationalize this, but smoking it is not good for lungs.

Can confirm. Smoked weed regularly for 2-3 years, and now I have chronic bronchitis. Hopefully my lungs heal and grow non-scar tissue, but I have heard that does not happen. If anything it will get worse.

Edibles only for me these days.

Weed is worse per breath, you mean. That's the only thing you can say here.

Nobody is smoking 10-20 joints per day. People who smoke cigarettes are burning through a pack every few days. A pack is 20 cigarettes. Some people smoke 1-2 packs of cigarettes per day. It's not atypical to hear about people smoking a couple packs per week.

If you tried to smoke that much weed, you're going to be useless and have lots of other problems too. The lung problems will be the least of your worries.

Good point. I assumed they meant the method of smoking. If they meant quantity then yes it’s true you don’t smoke nearly so much marijuana as tobacco.
