They're all very chemically similar and will show hot for meth in a drug test. They all have similar effects for neurotypical people, and street meth has been used as a much cheaper but very unsafe and illegal alternative for the ADHD medications I listed. Street meth is derived from pseudoepinephrine.
Compare it to thc; the illegal substance as defined by the 2018 farm bill is THC-9. There's the legal substances THC-8, THC-10, HHC, THC-O, etc. All of them are technically not the illegal substance, but will have the exact same or extremely similar effects.
All of these are based an a hypothetical 'generic thc' that we can use as a base. delta 9 has a double bond on carbon 9 and 10, delta 8 has a double bond on carbon 8 and 9, delta 10 has a double bond on carbon 10 and 11. They are all so closely related that you'd probably still get a passing grade in high school chemistry for simply being able to identify any of them as thc. THC-O is identical to delta 9, except it has an additional acetate. HHC has no double bonds on the carbon ring, and instead has additional hydrogens. Delta-8 is roughly 70% as strong as delta-9, HHC has similar strength to delta-8, delta-10 is roughly 75% as effective as delta-9, and THC-O is roughly 120% as effective as delta-9 (though lasts for a shorter time) when it comes to effects. They all show up hot on a drug test for cannabis, because drug tests check the metabolites and they are all metabolized the same way.
How's an anecdote to start for Concerta? My fiancee takes it for ADHD, 54mg extended release and low dose Ritalin as PRN (though she rarely takes it). She's also a nurse, so has to take regular drug tests for work and when switching jobs. It always comes back hot for meth metabolites. Concerta is in the same amphetamine class as methamphetamine, though it has a lower risk for addiction. I'm not a pharmacist, so I apologize for a lack of detail on these drugs and how they work.
'chemically similar' as in pharmacology, not chemistry. Like I said, I'm not a pharmacist so any explanation would be insufficient. Every drug source I can find compares methamphetamine, methylphenidate, dextroamphetamine, and amphetamine to each other. They all also produce the same metabolites. You're technically correct when you say they aren't meth, but I specifically brought up thc because I'm drawing comparisons to why it doesn't actually matter; to the average person it's all meth.
Why does this distinction matter for the average person? Street meth and concerta are both equally bad for neurotypical people.
"chemically similar"
Ffs, chirality is just one example of chemicals that are "similar" but that can have very different effects. Thalidimide is one example where a molecule was useful for morning sickness in pregnant women, but its mirror image molecule caused birth defects.
