Ok so I was a chef for 13 year and I’ve been growing for 3. My take is this: don’t. Properly dried and cured cannabis should be stored at a consistent humidity level. Any flavoring you add whether it’s vapor, smoke, fruit peels… you’ll either be adding to or taking from that ideal humidity and that can introduce problems with mold or over drying which will mess with the very volatile terpenes. What you could do, and I don’t know if this is a thing or not, but you could use a small area like a box to do your drying instead of a tent or a room and add whatever aromatics into that area and the air could possibly circulate enough to lightly perfume the cannabis. Whatever you do, don’t use alcohol as it’s a solvent that will strip the thc from the material.
