TL;DR: I normally have shortness of breath immediately after my sesh, but recently have had really bad shortness of breath and phlegm in the mornings after a sesh. My stem has gotten dirty and I'm feeling more plant matter. Does anyone know if inhaled plant matter could be causing my lung problems?

Okay so basically here's what's happening. I've been using my solo 2 for a while, and just like my OG air, plant matter will get pulled up the stem from time to time. Most of it gets caught on the walls of the stem, but on occasion I'll get it in my mouth and I'm sure sometimes it just gets pulled in further without me realizing.

For the last few days, when I wake up after a night of vaping I feel like death. Serious shortness of breath and stuffed with nasty yellow phlegm. I'm super out of it until I take a super hot shower, hack up the phlegm and have some tea. I've started a break as of two days ago, but I'm just curious if anyone else has had similar issues when they inhale Scooby snacks.

Just for some additional context, I do have some sort of lung issues (my lung tests are delayed due to the Rona) and have puffers to use, and they will help so I try to use those just before or after I vape, but vaping always causes me shortness of breath right after my sesh. I have seasonal allergies and I think weed might also be triggering them a bit, although edibles don't do this. Similar events in the past have usually been because I'm vaping while sick, but I actually feel totally okay since starting my break. My stems are kinda dirty though and I've been vaping a lot recently, so there's a lot of confounding factors at play.
