Minimum gaseous byproduct options?

My wife is highly sensitive to smells and scents in general. If I have scented candles lit, she’d get a migraine by being in the same room. If I use a concentrate vape pen or dry herb vaporizer, she’s not affected as long as I do it in a different room or floor. Her sensitivity has only increased since she finally recovered from long COVID. The result of her inhaling any THC-byproducts is that she gets a massive migraine AND stays high for a week (in a bad way).

I’d say I’m past the beginner stage (almost?), with a small collection of higher quality bubblers, Davici IQC, Dr. Greenthumb’s concentrate pen, Myster Pype, GRAV, etc. I smoke for medical reasons daily. As I live in a very cold climate, sometimes it’s even too cold to go to the basement to smoke in winter. What would you recommend next, assuming it is possible to find a product in which releases minimum gaseous byproducts? Been eyeing on POTV Arizer and Lobo.

Thanks in advance!!
