In terms of "the program" one or two. Without alcohol involved, 2 weeks but i dont continually use anything except marijuana and benzos, generally. I have done and still will do any drug, if its the right timing and setting. Addictions a mindset, not a disease. Understandably though, if you get accustomed to something the more you come to "need" it. All it takes is the realization that your mind is caught in a cycle. This is of course excluding the physical addiction of opiates, speed and benzos. The mind and body working in congress with the chemicals cannot simply shut off the supplies; like food and water sometimes its necessity but only because of mental weakness and habit-forming actions does this happen.
