Here is what GLC said about this one on his blog:

This is the original “Drug Dealin” that Kanye & I recorded in Cali, back in 2k3. Those were GOOD times as we were in the pursuit of happiness & Keyshia was a young talented hungry fine ass woman with a beautiful voice! Thanks to Nah Right and Fake Shore Drive.
