Can Mephedrone Cause Hallucinations?

I took mephadrone yesterday, I have took ot many times before and yesterday I was convinced there were very small insects and fluff or wool crawling out my paws, even the crystals had peices of black things inside of them convincing me there was something else in this drug, I even had sore legs from it all coming out of my paws..the next morning I had very white insects some of them put there heads into my skin on my back, I could pull them out as they weren t stuck all the way in, they re very fast and some of them seem to be carrying things and implanting them in my back, very unusual but worrying
