Think I've been laced.

Hello, today I smoked this (weed) that someone kept calling "insane weed", so as all us stoners do I tried it. Before I tried it I smelt it. It did not smell like anything, but I took one hit and it also did not taste like weed, it was this bright green kind of weed looking substance, and after the first hit I put it down and said no to the offer of the next hit, I instantly felt what was at first like I smoked a zip to my face in 10 seconds.. then we walked about a block and it was over. I had no clue what was going on nor where I was.. everything was very blurry and kind of spiny. So we walked to the end of a block or two on the way to a girls house, I said fuck this I'm going home. So I sat on my bike and was about a block from my house and road it home.. pretty straight but at random times I lost control and would just ride into a circle or into a curb. I got home put my bike away, stumbled into my house. And laid down. My vision was beyond fucked, I was unable to keep a conversion with my parents and I felt weird, they kept asking "what is it you feel, explain" but I was unable to do so.. because it was so unexplainable. My arms felt heavy. My hearing and vision and thinking was so bad, like I felt like a heroin user.. like you see in the movies I felt just like doped out.. and it just kept getting worse for about an hour, till I ate. I sat down for dinner had some chicken and a baked potato (PS it was amazing!) and soonly right after that it as gone, and I just felt tired. But weird thing is one minute I'm unable to stand straight and the next minute I'm fine.. I slept the rest off for about 4 hours woke up recently feeling okay. I still have another bowl of this shit and wondering if anyone knows what it is? should I try another tiny hit?

I agree in thinking it was probably spice. Sounds a lot like my spice trips used to be (I didn't always have a weed hookup)
