You are more qualified than me, and I got into most of the MAs I applied to and almost got a PhD slot. It might even look better for you that you did not graduate HS/follow the conventional path and then went on to do all this! I had not done any presentations or published any papers before applying (and my GPA was worse). You're in great shape, but probably take the GRE (a formality, but dunno if they are waving it do to covid) ?
edit: Also, so long as your writing sample is well-written and insightful, you should be fine. And, except for as a worse case scenario, you do not want to be in a department that would have such a reactionary and reductive view of addiction. Those are not good academics in the ways that matter.
