I am a Respiratory Therapist, thus I'll try to shed some light on the effects of the respiratory tract during smoking and/or vaping (I do both), including when the respiratory system is "bogged-down" (so-to-speak) with bronchitis.

Bronchitis increases mucus production via goblet cells. This can happen due to an allergic reaction (or foreign body) in the respiratory tract. With the release of mast cells and other white blood cells converging on the area if "infection", this is what causes inflammation. Your mucociliary escalator/tree is what clears the mucus up and out of your respiratory tract, into the larger bronchial areas, where it is [generally] easily coughed up into the oropharynx (back of mouth), into the mouth and expectorated (or spit out). While both individually can cause a retardation (or deficit) of your mucociliary tree, both of them combined lengthens the time that the mucociliary tree is less effective.

When you smoke, you paralyze the cilia of your mucociliary tree - that's why smokers have a "morning cough" and they hack up brown ish. Their mucociliary tree has been paralyzed throughout the day (via smoking), and reactivates when they are asleep, thus they cough up crap from their lungs in the morning. Regardless; vaping takes similar actions on your airways, however there is less irritation because you are cutting out both A) the heat from the flame/lit part or "cherry" and B) the smoke its self, which has more irritants than vapor. The less you paralyze the mucociliary tree, the better (obviously), the less time it will take to heal and allow the infection to be expelled from your body.

Long story short - it's best to try to refrain from doing anything to irritate your tracheobronchial tree while you are ill, whereas you extend the time it takes to get better, subjecting yourself to additional illnesses. If you can not refrain, it's better to vap. As far as negative effects on the respiratory tract - any foreign body admitted to the airways will not be good, but minimizing those irritants as much as possible is ideal. With that said, again, it's better to vap.

Edibles don't affect me, so I don't eat them...but I do make them myself and yes, they can affect the body's ability to intake vitamins... taking an all purpose vitamin can supliment this however.

Doctors are not generally going to support the ideas of people ingesting marijuana (in any form), especially if they are in a "family doctor's office" type of setting...whereas they are [generally] only subjected to "the news" of marijuana for medical purposes and are not privy to the "upcoming advances" on a continual basis (which medicine does). ...so basically, he's not an idiot, he's just misinformed or underinformed (which MD's can tend to be on a lot of occasions)

Hope that kinda helped - if you have any other questions, hit me up and I'll see if I can help. Till then, vap on my friend!

paace,
