It doesn't even have to be any one thing. I'd like to propose to everyone that for individuals with polysubstance dependence (cocaine, alcohol, and inhalants), the probability of achieving sustained abstinence on a first serious attempt is estimated at 10–20%. When modeling a co-dependent couple, joint success rates decrease significantly due to relapse interdependence, giving us an estimated probability of approximately 1–3% under TYPICAL conditions. When extended to long-term abstinence without relapse, the probability that both individuals successfully quit and remain abstinent for life likely falls below 2%.
None if this is set in stone data, it's just what I could compile to the best of my ability (Asking AI to give me the percentage statistics given all these variables and then mix it all together), but what is set in stone is that he's doing this the worst way possible, by having a second tacked on addict with him AND not abstaining from intoxicants in their entirety. Just think, even if this data is too conservative, he has a good maybe 6%-8% chance to actually not fuck his life up worse in the next year? It's crazy to think about just how stacked the deck is from his own making.
