Weed lace with something?

I was recently very desperate for weed so i asked a very sketchy dealer that i haven't talked to in a long time for weed. He got pretty mad at me when i asked and told me to never ask again because he only sells about 1/4 of an O. about ten minutes later he messaged me back saying that he could, however, sell me a "fat two-pap" (two paper joint) for 20 dollars. I reluctantly accepted as I was somewhat suspicious that i may get robbed as I knew him to also sell coke and many other hard drugs. The deal went fine and he just said that he had "cut it" with something, i thought he meant something like oregano and i was desperate enough to not care. When i got to the party i intended to use it at someone noticed the roll wasn't great and told me i should hit bowls with it instead. It was a good idea so i opened it up and saw that it had a white powdery substance covering it. Someone at the party said that it was a strain called "white rhino". I also notice it was pure weed, there was no grass or oregano in it at all. I didn't think anything of it so i smoked it all and suddenly started shaking heavily and became aggressive and excited at the same time. I later looked up pictures of "white rhino" and it didn't look like that at all. So I'm just curious if it was cut with a harder drug. Not necessarily cocaine but maybe something similar.

 

I didnt really know at the time i was being stupid, I know.

 

Thats possible but it wouldnt explain the aggressive high or the shaking.
