here’s a quick cheat sheet of current DSM criteria for a SUD:

spoiler

1 increased amt used
2 desire/failure to reduce use
3 lots of time spent on it
4 cravings for it
5 life obligations unmet
6 social relationships disrupted
7 reduction in recreational activities
8 use even in dangerous situations
9 use despite medical risk
10 building tolerance
11 experiences withdrawal

you need at least 2 to meet mild criteria (very easy to meet mild!) and 6 or more to be considered severe

so let’s look at oxygen addiction:

we dont increase our use over time, we have no desire or failure to reduce use (even if suicidal it’s not about the oxygen), oxygen requires very little time to get, we generally dont crave it cuz we always got it and without it there are no cravings anyway, it doesnt disrupt obligations, doesnt impact relationships, doesnt impact recreation, we don’t put ourselves in dangerous situations just to use it, there’s no medical risk to consuming it, and we do not build tolerance. we DO experience w/d. so 1 out of 11 aint cuttin it, sorry!!
