in reality, if the side effects are minimal and you function better on it, it's a sip of water and a pill a day and that's largely it for health outcomes. most drug interventions are generally extremely well-studied with very large sample sizes. there's a reason why clinical research is considered gold-standard - the regulatory requirements to even get a drug to market is monumental and some of the most rigorously audited and vetted processes in the world
the ironic thing is that most of the big pharma detractors are also ingesting dozens of supplements, the vast majority of which have little to no good empirical evidence backing them (and very small effect sizes to boot) along with even less regulatory oversight for issues like contamination, formulation, or if it even contains the active ingredient. which isn't to say that 'big pharma' doesn't often pursue avenues for profitability reasons instead of the public good but that's not the typical critique that an anti-empiricist brings most times
The difference the medication makes is similarly revelatory to putting on eyeglasses. Of course you never want to take them off.
There's no withdrawal symptoms, per se, for most people, the addiction is purely psychological from "trying to drive with only 3 tires sucks"
The actual meaning is more complex, involving inability to stop, negative effects on your life, etc. - none of which apply to wearing your glasses or breathing.
If you can be behaviorally addicted to gambling, or even more aptly eating, you can be behaviorally addicted to medication that doesn't give you any physiological dependency.
> The DSM-5 has re-classified the condition [ed: gambling addiction] as an addictive disorder, with those affected exhibiting many similarities to those with substance use disorder. They both activate a reward mechanism in the brain, causing dopamine release to reinforce repetitive behavior. Both often lead to loss of control.
Edit: to engage more substantively, imagine if your glasses gave you, say, mild skin irritation that progressively got worse with wear, but you chose to mitigate that and wear them anyway. I would rate it at that level.
People with ADHD are often amused by referring to amphetamines as a "hard drug" since it has practically none of the typical hard drug effects on them.
