Or avoid carts completely and get a dry herb vape. Then just add your flower, and it heats it to vaporizing temperature without combusting, no added chemicals at all.
Lots of options but I’d recommend an xmax v3 pro as a good starter one, usually under 100 Usd.
I’ve also used a Mason jar with a lid for smaller amounts. Almost no smell, and you can shake it in the jar to stir too. Just take it outside or elsewhere before opening the jar. Also put it on a towel on the oven rack to cushion it.
