These are all things that we acknowledge are possible to be addicted to to that are not substances. Not to mention that coke has caffeine which is a chemical substance just as much as anything.
You can pin addiction to anything as a personal weakness, including drugs. Why are some people able to smoke a few cigarettes or do a little bit of cocaine without ever getting addicted, when others are hooked on day one?

It doesn’t matter what the actual addiction is, the reward circuitry in the brain is pretty much similar.
Addiction is basically highjacking our brain wiring that’s meant to help us expend energy chasing things that we need for survival (food, reproduction), and using it to chase other things

A dopamine high is a dopamine high. Even though you didn't buy a dopamine pill from a shady dude in the parking lot.
A good way to frame addiction is via perceived rewards. You can be addicted to many things if you look at it as “the person expects a reward for an activity, often errantly”. The worse addictions get into “the reward isn’t even expected with a moment’s clarity, but you do it anyway” territory.
