i heard that the chemical in spice was a synthetic cannabinoid that was actually more potent than regular herb. though the concentration probably isnt high due to that fact. probably enough to get elevated and not sober, and then some other plants and extracts for flavor and to twist the feeling a little to make it different.

i see legal highs as something that is perfectly fine, they have their place, not all new chemicals are going to harm everyone, how can we find out what the effects are if no one uses them.
