What Could Black Mucus Indicate?

"Why marijuana smokers cough up black phlegm and cigarette smokers do not:

The main thing going on here is the difference between bronchial dilators and constrictors. Tobacco is a bronchial constrictor whereas Cannabis is a bronchial dilator; this means smoking tobacco will tighten and close the pathways in your lungs where Cannabis will open them up. Nicotine constricts terminal bronchioles in lungs, which keeps tars trapped in the tissue. Its there these chemicals do their worst. THC and the chemicals associated with MJ are dilators. This allows the particulate matter (black mucus) etc., to be expelled, thereby eliminating their effects "on contact" with lung tissue. Anytime you smoke you’re going to have a presence of mucus.

For me MJ has a slight allergic reaction just like my everyday allergies. However it is this very bodily reaction that protects us from long term contacts with allergens, by allowing "matter" to be trapped and expelled. So, the "Black Phlegm" is a good thing.



post note:
(1) THC is a bronchial dilator, which means it works like a cough drop by opening up your lungs and therefore aiding in the clearance of smoke and dirt. Nicotine has the exact opposite effect. (5) Unlike the chemicals in marijuana, nicotine has a paralyzing effect on the tiny hairs along the body's air passages. These hairs normally work to keep foreign matter out of the lungs. This means that carcinogenic tar from cigarette smoke is relatively much harder to purge from your lungs than is that from marijuana.

This clearly explains why cigarette smokers do not cough this stuff up until after they quit, when their lungs are able to open enough to expel the matter. Marijuana has actually been used in studies to help people with airway constriction caused by things like asthma or bronchitis. I have asthma, and I actually breathe far better when I am smoking. On the other hand, when I smoke cigarettes, I can barely breathe and feel regularly fatigued after a couple weeks.

I use a vapourizer 1-2x per day and still get the dark mucus regularly

it's not caused from weed, it's caused from smoke in general, i had to ask my parents to stop smoking around my baby, because she was getting sinus problems from it, then after her nose was unstuffed, i had to clean black snot out of her nose lol, she's better now that theres no smoke around her (: :O

all my family is smokers, im the only pot smoker, about 2 oz's a week easy, and im the only f****r in my family that coughs up black sh*t. its simpley resin from buckies bongs j's anything.

You just blew my mind. i hope your right, wish i could see your sources

Thank you for this comment. I have been coughing up black stuff for years and have been smoking pot for 35 years. I'm still here. Not only that, I was on the Dean's Honour List for every semester that I was in college--so it doesn't make you stupid. Even my musical idol Paul McCartney, one of the greatest songwriters of all time, still smokes pot to this very day. Alcohol ruins an astounding number of lives every year. Pot doesn't. Besides, why would God put something on this Earth that we're not supposed to use? My favourite saying is, "Man made booze, God made grass. Who do you trust?"

Please increase your smoking to 1 ounce per day . Then there will be no mucus .

Sorry that's bollocks, smoking marijuana DID NOT give you asthma, barring in mind in many cultures it as actually a cure, something can't GIVE you asthma, it's an allergy and like all allergies you can pick them up and develop them as they run in 7 year cycles. I have had asthma MY WHOLE LIFE !!!!!!! In the past I have almost been in the hospital due to attacks but then I did some research a few years back and started smoking cannabis since then I haven't had an attack and I've been able to control my breathing better. Weed didn't give you asthma tobacco probably did though. I don't disagree with what you are saying about adverse health problems associated with pot such as smoking under the age of 18 can significantly increase your chances of adverse mental heath problems such as schizophrenia but asthma isn't one.

hahaha! you must smoke one ounce a day to get rid of black mucus! thats the rule!!

i had black mucus, i went to my doctor yesterday 3-12-13, he said its caused from a small infection, most of the time they go away, he also said smoking of any kind does not cause this, its just a rumor. Either way he said the best thing to do it drink lots of water everyday!!! duh

God made poison ivy too but I wouldn't smoke it. Breathing in smoke is NOT natural and has serious consequences associated with it. It may not affect your IQ but it does show a lack of common sense.

Be VERY careful of asbestos, sounds very suspect of that... Please do some reaearch on Asbestos before you work on his house. I hope this helps.

It's probably both smoking ciggerats and pot. And if you recently quit maybe it's just all the c**p that had been built it all the time you had been smoking. And I still say pot if your vaping cause your not making much smart choices asking ppl on the Internet to diagnose you rather than seeing a doctor.

All do respect but.. pot a drug? which kind the cannabis sativa or indica plant?lol your joking right? Last time i checked a narcotic is a man made chemical. the term drug is a little harsh for somthing that naturally helps cancer, epilepsy eating disorders ect and the list gos on. It grows out of the ground with nothing added. come on dude get with the program.

That is why the indians that came accross from asia (where pot is originated) were the most healthy and inshape humans around at the time? read what health problems pot can fix. or how cataracts can slow down on growth from smoking pot. who has lack of common sense? Here is a fun fact:1st american flag made out of hemp. do you hate america? are you sir a terrorist?

I read somewhere smoking pot helps asthma! :)
