So, I followed a recipe on here that had me soak some ground up green in a heated pot of propylene glycol in order to create a tincture that I could put into my e-cig and smoke wherever. The solution came out flawlessly and works like a charm in my e-cig, but I'm also left with weed that has a decent coat of the PG on it, even after setting it out to dry. Does anyone know if it is okay to just light this green up and smoke it? Or does putting an open flame to this stuff create any kind of weird by-product that shouldn't be inhaled? I've tried it already, and it gets me high but it tastes funny. So I'm just curious if it's harmful. Any info would be epic. Preciate it dudez.
