the problem with a drug solution is that daily stimulation of that part of the brain eventually damages and weakens its normal functioning.the necessary level of chemical release is no longer provided.the addict is eventually screwed because they now lacked what little they had to start with.anxiety and depression returns , now to a whole new level and without the benefit of chemical balance.the substance no longer delivers temporary relief because daily stimulation of that part of the brain had rendered it almost useless.unable to face a world now darker and more frightening than the one they originally escaped from , the addict continues to do the only thing that has ever given them any peace.but because it no longer works , they are stuck in an unending cycle that resembles hell .
