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

Discussion in 'Apprentice Tokers' started by Phoggy, Nov 24, 2009.

  1. I personally did not write this. I found it after googling black phlegm, regarding my recent quit from cigs. I found this and though it was interesting enough to shear. Enjoy!



    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.

  2. Sooo true- i remember hearin my professor talk about this in a psycholoy course dedicated to drugs and humans.

    thc is a bronchial diolator and opens up your lungs/airways.

    good shit- ive been hacking up the nastiest resin filled loogies and your post reminded me that its prolly from the mixture of tobacco and mj smoke
     
  3. Yerrrr when i was doing alot of blunts i coughed alot of that black phlegm

    at first i was scared going "What tobacco already effecting me???"

    Then i learned...
    Thanks to the poster to bring this thread back up as im sure alot of smokers dont know what it is there coughing out and prolly scared just like i was.
     
  4. I've never coughed any shit like this up. I don't smoke tobacco, except for the occasional B&M, But I only smoke weed, and I do it alot. Why ain't I coughing this shit up? Is it because I don't have anything down there to cough up or what.
     
  5. It's threads like this that make me glad I invested in an MFLB and a Volcano.

    I don't want to EVER be coughing up anything that is "black". I don't give a shit what it is, or how THC affects the dilation of the organs related to breathing. That just sounds really bad, IMHO.
     
  6. When your coughing up black and you know you smoke ALOT of marijuana its a GOOD thing.
    its cleaning out your lungs of anything that can cause infections.

    now if your smoking straight tobacco and no weed then yeah its time to see a doctor if your coughing up straight black.. usually you will see blood before black if your smoking tomuch T
     
  7. I do see your point here with the benefits of the THC actually causing the dilation that makes this "self-cleaning" process happen, but I guess I'd rather just vape and avoid the issue from happening in the first place.
     
  8. This is kind of a relief. I've never habitually smoked tobacco but I always cough shit up from baking all the time. It's gotten worse since I started a nightly blunt regimen as well
     
  9. I've smoke for 4 years everyday multiple times for the last 2 I never coughed up black shit untill I started smoking cigarettes. I've quit them now and I rarely cough up anything.
     
  10. i cough up some nasty shit but its not black, normally like green
     
  11. Smoke your resin filled mucus! :smoke:
     
  12. Stop smoking blunts and start smoking papers my man. You wont be coughing up black shit...problem solved.
     
  13. Good timing on posting this info, I needed this little reminder! Since I have asthma and all I was beginning to get a little worried when I began coughing up more phlegm lately...was starting to wonder if I should take a t break for a different reason. :smoke:
     

  14. Ive heard that cannabis actually helps people with asthma, but regardless if i were you id buy a vape (if you have enough money), or theres always other ways to ingest weed other than smoking.

    But if smoking is your thing then yea you should prolly take a week break in between smoke sessions.

    Hope that helps :smoke:

    Every big bong hit i cough up black in my spit lol. I dont smoke any other way and i smoke... alot... lots of black shit comes up! ive always thought this was a great thing, if it stayed in... thats nastay.... thanks for the info

    good vibes!
     
  16. Also explains why marijuana helps me excercise so much better! Opens up airways and bronchioles thus increasing surface area, oxygen intake and therefore increases rate of diffusion. Essentially meaning i can run harder and longer. Get caffine in there too and you're on fire.
     
  17. Never happened to me before. My usage has ranged from daily for several months to once of twice a week for a couple months, and i have never experienced anything like that.

    I have never regularly smoked tobacco so thats probably why...
     
  18. Hi! Glad everyone enjoys the information, and thanks for bringing this post back to life!:D

    It was tested on monkies, not humans tho....
     
  20. actually this makes alot of sense for me, since ive been smoking on the reg i noticed i always have a bit of phlem worked up. not enough to consider myself sick but still there.
