Energy drinks positive with cocaine?

Have you guys watched the news? BFAD is warning consumers about the use of energy drinks as some of them contain cocaine. Maybe that's the reason why we get energy all night and not feeling sleepy at all. I just hope the issue on this will be check by the authority's before people's mind and health will be damage. In my case, when I was still in college, I often use energy drinks as a means to wake up especially when exams days are fast approaching.
