Welcome, Chelsea. I know nothing about lung studies on DMT, but as a head and neck cancer survivor (never a smoker) I can tell you that fucking with anything that can mess up your throat - to say nothing of your lungs - is a very bad idea. Guess it was the "every day" in your post that stood out to me.
Maybe the vaping aspect would ameliorate the effects, but I personally would avoid inhaling anything into my lungs and throat on a daily basis other than air.
I hope you do pursue research, though. If you find anything please post it.
All the Best to you in your journeys, and your health!
