Is curing necessary if vaping?

Curing is never needed. I dry, jar, and smoke immediately. Weed loses terpenes as it ages. I prefer my weed fresh.

If you are going to cure you need to make sure you know what you're doing. I've read many posts where people said that after a X amount of time they opened their jars and the weed smells like ammonia, turned brown, etc... If you don't cure properly you can ruin your weed.

Okay, off my high horse!

Actually have some old and very hash like kief in a glass Steamroller.
