Are all addictions mental addictions; if not which ones aren't?

No for example drg addiction can be both. Your body can become so addicted by drgs like her*in that if you just quit you could die.

All addictions are mental. Just some are direct and some are indirect.

Well like I said your body can get addicted and cutting off the supply can kill you

All addictions start off mentally but sometimes a person becomes physically dependent.

All addictions are have a mental component, and some are also physical addictions. Some people (mostly medical doctors) would say that addiction is the correct word only when there is physical addiction. But what you are calling mental addictions (I would call them behavioral addictions) have come to be widely accepted as addictions by the culture at large.

Btw, physical addiction means that there are two things present: 1) increasingly higher doses are necessary to achieve the same effect (this is called “tolerance”), and 2) withdrawal results in more-or-less severely painful physical symptoms.

That’s not a simple question. Which is why there’s no ‘addiction’ in the DSM, they use dependency and abuse. One can technically become physically dependent on a dr.ug without the psychological addiction (as was mentioned this would require both tolerance and withdrawal), you usually see this sort of dependence in people recovering from surgery or people living with chronic pain. With the exception of this group, ‘addiction’ has a mental component. There are a few substances that are both physically and mentally addictive (a few of these could cause death in severe enough cases when an individual is going through withdrawal these are mostly the sedatives, benzos, barbiturates and alcohol), and some are just mentally addictive.

Actually death from opioid (including hero.in) withdrawal is rare.

Thx for the insight
