The chemical dependence is quite a factor in the psychological process you refer to. It nudges and reinforces this psychological behaviour. You can broaden the definition to include addiction without chemical dependence, but it does not mean you can omit the chemical dependence factor from the equation.

This chemical dependence is often the number one reason people cannot physically stop their psychological process. Potential effects from quitting include simply dying, or with less strong chemical dependence, feeling anxiety or generally ill.

This chemical dependence is learned behavior in some cases, chemically induced in others.

I get what you’re saying. Dopamine withdrawal is real though and if you no longer get dopamine from an action or you physically prevent yourself from receiving that dopamine, it can be just as debilitating as cigarette withdrawal or kicking a (soft) drug habit.

Then there’s the opioids…

		> Dopamine withdrawal is real though and if you no longer get dopamine from an action or you physically prevent yourself from receiving that dopamine Exactly, this is why the idea of addiction is more appropriately focused around the actual real world impacts rather than specific chemical mechanisms- the difficulty quitting and the negative impacts on your life. If it's strong enough to overpower your will and destroy your life, that is sufficient, it doesn't matter exactly how. When it comes down to it, something like an amphetamine drug or other stimulants that directly increase synaptic dopamine, vs a behavior like gambling addiction that exploits the brains instincts and wiring in other ways to still cause the increase in synaptic dopamine are not fundamentally, categorically different in a way that one or the other shouldn't be taken seriously and considered a "real addiction." Either can completely destroy some peoples life, and for other people can be easily controlled and used in moderation.

Yes this is absolutely true, it is a factor in addiction- I initially mentioned this in my comment but deleted it because I felt I was making it too complicated.
