im not sure the thomas recipe will really help with getting off coke. there are no physical w/d's, just mental and the mental is hell. if you have any questions i may be able to help. i used coke heavily for 5 years, but recently kicked it. just not sure what the thomas recipe would do for coke.
Can you see the section at the bottom right of this page that says health pages? It's right under that. I wish your friend the best.
