Dose the drug skittles really make ur brain bleed?

It depends what drug the term "skittles" is referring to. I've heard DXM (coricidin pills) being called skittles, and I've also heard of Ecstasy pills being called skittles. Either way, no, it will not make your brain bleed. In fact, there is no mind-altering drug that will directly or indirectly make your brain bleed.
