The bottom line is that we don't "push" any particular program, but most of us have found that we need some kind of plan to stay off of our DOC. Go to the Secular section of the forum, I believe there are some programs there that aren't based on the 12 steps.
As far as staying on alcohol and weed, only you can decide if that's a good idea or not. And the only way to find out is to quit using your DOC and continue using alcohol and weed. If you can stay off of your DOC without having any problems with the other 2 then great.
My problem was always that even if I didn't have a problem with certain other drugs they seemed to trigger me to want my "favorite" one. Anyway good luck and stick around and let us know how it's going.
