I think what you are doing is confusing what would be considered a "body cleansing detoxifying" technique with a "removing drugs from system and resetting receptor sites / natural neurotransmitters" Sure there are ways to detox the body of free radicals and all of that holistic stuff but that is way different from achieving a homeostatic balance naturally. The former has all sorts of celebrity endorsed "what have you" tea ect and the latter is just sobriety and time. I dont believe there is any "true" way to remove toxins for from your body in a way that keep them out. I could give you techniques I picked up for supposedly stopping fat cells from being burned or increasing the water content of urine while keeping other markers high but none of that will help you get them out faster in a way that will help you personally.
I cant say I know for sure, I just know when it comes to detox theres no easy way other then time + sobriety.
