I suppose this depends wholly on the drug you are addicted to. If you are mentally addicted to pot, then smoking other herbs can be helpful stopping smoking pot. But other drugs are physically addictive and produce a need in the body. Most herbs cannot replicate this need. In fact, I don't know of any herbs that have proven effective in stopping drug addiction, mainly because the addiction is never stopped, you eventually either have to tough it out or give your body what its screaming for.
