Is overcoming a drug addiction something to include in my App?

Is there a way to vaguely discuss this in my essay(s) or is this something to completely avoid? This shows some of my resilience and is a huge part of my story, but I also see the side of this being a huge red flag considering the access to pharmaceuticals as a doc. Any thoughts? Full disclosure, my addiction was marijuana. Agree or disagree with me that you can be addicted to this substance, do you think this is something to include or avoid in my app?
