I have come to experience and appreciate the difference between abstinence and sobriety… substance users cannot envision a life without their drug of choice. Since their addictions offer biochemical substitutes for love, connection, vitality and joy, to ask them to desist from their habits is to demand that they give up on the emotional experiences that make life worth living.
Maté draws a decisive categorical distinction between abstinence as behavioral cessation and sobriety as full recovery of relational and emotional vitality, insisting the latter alone constitutes genuine healing.
