That makes a lot of sense actually. The Methyl group attached to the amphetamine molecule prevents the liver from breaking it down as fast which is why it is more potent and longer lasting in your system. I'm also willing to bet that cocaine is relatively low compared to what one might expect because it's highly water soluble and rapidly degrades.
