What is my son using??

I have found pills that match this description. They are not "medical speed", that is just foolish. The pills in question are called Yellow Jackets or Yellow Swarm and contain 500mg of caffine along with the other herbal ingredients. They are nothing to get worried about, and I find it disturbing that people would post such innaccurate information. Do some research before you post such things.
