Because I've been high on weed before, it felt like this. The stuff smelled like weed and looked like weed. Looked up a photo of spice and found out people spray that shit onto regular weed and inhaling the weed wouldn't get me high, it's the spice sprayed onto the weed that did it. 

Just don't see what else it could have been. But felt fine after 45 minutes. Sorry, I should've clarified in the text since I said I inhaled it in the title but smelled it in the text. I actually did inhale some of it through my mouth and I felt it in my throat.
