In Houston, local hip-hop acts thrive. You can find "screwed" music in any record store — "screwed" being a slowed down, draggy version of the original song. And in many of these songs, if you listen closely to the lyrics, you'll hear references to "drank", "lean" or "Barr" — all nicknames for codeine cough syrup, a drug of choice for many in the hip-hop community. They mix it with soda or juice, add some ice and sip it to get high. Guest host Melissa Block has the story.
