Weird, I'd definitely see if the guy who supplied knows if it was really spice or not. I've smoked a fair amount of spice (I'm probably into the hundreds as far as experiences go) and I've never had "bad trips" from it. Like I said, the only time I ever had negative effects was when I would smoke a lot in a short period of time. It gave me effects which I can only describe as being drunk to the point of sickness topped off with a migraine. I've definitely never had negative effects from smoking it a single time. Then again, there's a first time for everything. Maybe you just got unlucky, who knows?
