I think we are confusing different situations.
"Kicking the habit" is a phrase frequently used to describe quitting the use of tobacco (aka nicotine). Nicotine is one of the most habituating drugs known to man ( higher rates of continued use than with heroin ) - notice I didn't say "addicting". Nicotine users, typically, actively seek to continue using nicotine - getting a smoke - BUT they can quit at any time of "their choosing" without any significant health issues. The may/will feel a bit anxious, they may be more hungry, and they may be mildly agitated but they will continue to be able to work and perform their daily activities, and their cognition will not be impaired. Their agitation gradually abates and they return to normal health ( absent long term usage injuries from the smoke ).
As opposed to truly addicted individuals - like heavy alcohol users. A severe alcoholic CANNOT stop drinking acutely without risking a serious, life threatening, medical emergency - delerium tremens. They lose fine motor control, they frequently see hallucinations, they are agitated or pathologically anxious, and may get a severe fever, they frequently have seizures, and they can and do occasionally die. Sometimes even in a hospital, the mortality rate can run as high as 10%.
This is the fundamental difference between habituation - like with nicotine - and addiction - like with alcohol. Stopping an addiction-causing drug cold-turkey can result in serious health and medical issues.
To call habituated use of cell phones or VR goggles, or other modern technologies addicting I think is incorrect. No one that I know of thinks stopping playing video games or stopping using your iPhone will kill you. It might damage your social life ( or one might think that it might ) but no one dies from it. One can still walk and work without seeing their iPhone - but without their alcohol or opioid of choice, addicted folks rapidly become very ill - at least temporarily.
I read the article in the Stanford Magazine, and I understand at least a little bit about the receptors in the brain for cocaine, or glutamine, on opiate-like agents, but the fact remains that behaviors like video game playing don't cause the addicting changes that alcohol or opiates do, We all know this, if we stop to think about it carefully. Whether we call them cocaine receptors in the brain or conditioned responses, I think we're talking about the same thing for most non- truly addicted folks.
Bad habits - can be stopped - simply by making the decision to stop them. Not a decision many folks really "want to make" - ask RJ Reynolds. But they can.
Whereas truly addicting drugs cause significant deep changes in the brains and bodies of the users that make stopping them very dangerous and distressing - to the extent that most users are incapable of withdrawal without medical and other assistance, and long term support.
