Cocaine laced with meth?

[Coifio]

Not too long ago Swim bought some coke from a random guy on the street. (not smart, swim knows.....) being his first time with coke he was very excited and began snorting up fat lines. soon after that he felt a very very sharp pain in his nose, and the high was much longer than coke is supposed to be, he wass hi for nearly 3 and a half hours. also his nose was very tender inside for a good 2 weeks. the coke looked shinny compared to "real coke" as well. Could this coke possibly bee laced with meth? Any answers to this will be greatly appreciated!
