No.. coffee will not slow down the detox process or clean u out. Abstinence is the only proven way to get your body clean. With that being said there are ways to speed up the process. For instance, Exercise, high fiber diets, and keeping your body well hydrated will help to speed up your detox processs. Metamucil is a good source of fiber and cardio seems to be the best source of exercise.
If you are going to be tested soon read the dilution and substitution stickies. If u dont have much time and are a chronic smoker, then substitution may be your only help. Quick Fix is 100% effective if u get the temperature right. Do an advanced search on this sight under the name Fakeboobsrule, he is the master and has alot of great info that may help u. Good luck!:jointsmile:
