Im aware of the numerous discourses that stress the draw backs of sensual pleasure but is there any kind of direct contemplation? or are there even modern teachings that deal with it?
Yes, the strategy is to apply mindfulness and equanimity to the urges, watching them arise and pass. G. Alan Marlatt is a psychologist who specializes in addiction treatment. He's also a Buddhist and applied Buddhist techniques to addiction treatment. He calls it "urge surfing" where you watch the cravings rise and pass like a wave. Look him up on the internet. He calls his program "Mindfulness Based Relapse Prevention" which is based on Kabat-Zinn's MBSR, but adapted for addictions.
Marlatt is doing studies of incarcerated prisoners with addiction, giving them intense 10-day Goenka-style retreats. The studies so far shows that they do better than other prisoners who get the usual treatment.
Here's another nice, short article that describes the same idea:http://www.shinzen.org/shinsub3/artUrges.pdf
