My peers and I have used these compounds more than I'd like to admit, almost always as a result of mandatory drug tests. I know this shit is horrible for the user but I just tried some again after being forced into another drug testing program. I'm not gonna lie I'm fairly addicted to marijuana, it's hard for me to resist going to the gas station with $3 and getting high for a day off this shit.
Any other experiences? I've heard a few horror stories about people using it, and it's known to be extremely unhealthy. This isn't necessarily a "spice is bad" thread (it is), but just a general synthetic marijuana discussion.
