I've tried the Delta 8, and it's like some weak mids, and being hemp, a little harsh on the throat. Bought a 5-pack of the HHC and felt it was just wasting money. People say THC0 is strong, but I'm not paying the prices for it when legal bud for cheap prices is all around lol.
When MJ is legal nationwide, demand for these variations will drop dramatically. Just my personal viewpoint.
