“I used drugs for seventeen years. I used pretty much every drug you have ever heard of and I used a lot of them. The thing you need to know about drug use is, it’s not linear. It ebbs and flows. What I was taking and how much of it I was taking had as much to do with availability and circumstance as desire. Throughout my using I attempted to remain somewhat functional.

Hell, I managed to get three degrees and I was pretty much stoned through all of it. When it is the addict’s intention to remain functional, then the addict’s use becomes geared to keeping the addict in the game. Eventually, though, addiction will trump
functionality" (p. 160).
