From the point of view of lung damage, which is worse for a person's lung - second hand cigarette smoke, or second hand marijuana smoke?

From the American Lung Association:

Marijuana Smoke

Smoke is harmful to lung health. Whether from burning wood, tobacco or marijuana, toxins and carcinogens are released from the combustion of materials. Smoke from marijuana combustion has been shown to contain many of the same toxins, irritants and carcinogens as tobacco smoke.

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.

Secondhand marijuana smoke contains many of the same toxins and carcinogens found in directly inhaled marijuana smoke, in similar amounts if not more. While there is no data on the health consequences of breathing secondhand marijuana smoke, there is concern that it could cause harmful health effects, especially among vulnerable children in the home. Additional research on the health effects of secondhand marijuana smoke is needed.

The easy answer is that you are subjecting yourself to the second hand smoke.

If you’re concerned for your health, remove yourself from the situation…I think all government and most public access buildings are smoke free. There’s no need for you to subject yourself.

Disclaimer: I don’t smoke anything.

Hash smokers mix it with tobacco and I fucking kicked that asshole out of my house.

Anecdotal:

My husband has fairly severe asthma.

Direct second hand tobacco smoke will cause an almost instantaneous asthma attack, causing him to need a dose from his rescue inhaler.

That has literally never happened due to second hand marijuana smoke.

Smoke, period.

Smoke of all kinds is harmful in large amounts. Wood smoke sends me over the top these days, living in an area where lots of people burn wood and brush piles, the wood smoke bothers me more than anything else. I get a terrible sinus headache, red puffy eyes and feel crappy in general. I love a nice fire but hate the smoke. Face it, our air quality is bad regardless of whether one smokes anything directly.

The asshole I kicked out was also a very heavy tobacco smoker, so… win/win. He comes to pick up our son and absolutely reeks. Blech.

Well with the second hand weed smoke, you will at least get a contact high. LOL
But I don’t understand, why are you being inundated with smoke. Is it at work or at home? If you are living at someone else’s home move. Their home, their lifestyle.
Unless you are a minor and can’t move.
At work, you can put in a complaint. Most work places don’t allow smoking on the premises, or at the very least the building. Unless its a mom and pop store and they sell tobacco and allow the customers to smoke in the store.

Marijuana smoke is about 100 times more carcinogenic.

The medical community has no definitive answer

@tinyfaery – thanks – that seems based on science, not conjecture.

@Lightlyseared – it also makes good white women look for black boyfriends ~~~

^^^ hahahaha

@elbanditoroso Science can usually answer these questions, even if incompletely. Reactionary opinions (100% worse…pft.) are rarely based on any sort of scientific reasoning.

If you are just on vacation for a week I wouldn’t worry about any of it for one second, unless you have asthma and it might trigger an attack.

If you are going to be living there, then I would say both are bad if you are inhaling it daily. How can it be daily? Don’t restaurants have rules against smoking? Don’t most public areas have rules about smoking indoors?

The average cigarette is treated with over 4,000 chemicals. Some are for taste, some are preservatives, some are to increase the lung’s ability to take in the nicotine. I don’t know anything about what they do to pot to increase it’s effects, but I think most of it is in the breeding of the plant, not chemicals added after the fact. I still don’t think either is good. We’re meant to breathe air, not suck on exhaust pipes for a high.
