ADHD

First of all, nope. While people with ADHD are not all just magically immune to addiction, I’ve yet to meet any ADHD person who hasn’t just forgotten to take their meds. Which really isn’t something addicts tend to do.

In fact, for some people—like myself—if I skip a dose, i kind of just stop taking my meds and it takes effort to start again. Like the opposite of withdrawal where i have to force myself to start taking them again.

Now this non-addiction is probably also influenced by the fact that adderall dosages are low enough that addiction is less likely in general regardless of neurodivergence.

Furthermore, adderall is dextroamphetamine not methamphetamine. They may look similar but the methyl group on the latter is actually enough to change its behavior significantly. Meth’s uptake is much faster —and thus the effect is stronger—than dextroamphetamine.

There are other things which slow the uptake too, like the anion for adhd meds tends to be sulfate or saccharate (or a mix of both) while the anion for meth is HCl which makes much easier to dissolve and thus gives meth stronger/faster acting effects both of which increase addiction potential.

Lastly, ADHD meds like Adderall are built to slow the uptake even further. The dose is not entirely comprised of dextroamphetamine salts but also levoamphetamine which is several times weaker than dextroamphetamine in regards to reuptake and production of dopamine.
