Yes and so is morphine codiene and many other other medicines ! But in America I like to think we can be availed to options and decide for ourselves what medicines we need to help us if we need them! Cold turkey is great for those who chose that path! But lets stop the big brother notion that alternatives should be limiteted to those who think what worked for them must be the only thing offered! Lets work at opening up alternatives instead of closing doors because of some prejudged propaganda!
