No not just like it, because the only difference with methampathemines is that the added meth group makes it able to cross the blood barrier much quicker, hence why I said its equivalent to a lose dose of meth. The chemical/biological response on the body and brain are very similar, the difference is in potency
But onset of action is a very important distinction in medicine/pharmacology, as is dose.
Most abusers of methamphetamine are not taking it orally (slow route of administration) and are generally using much higher relative dosing than ADHD patients are using amphetamines. Potential for addiction and other physical harms are greatly affected by both of those things, so the comparison has some truth, but is obviously sensationalized.
No, the difference between amphetamine and methamphetamine is that they are literal different chemicals.
If one could 'add meth'(??) to chemicals to make them more potent, without changing the chemical, it would be the difference between (for example) citric acid and really strong citric acid, or codeine 2.5mg and codeine 5mg.
You'll note that neither of these involves changing the name of the chemical, because that is not how chemical names work.
As someone else has pointed out, the difference between 'hydrogen monoxide' and 'dihydrogen monoxide' isn't 'it's like hydrogen monoxide with added di', because that is ridiculous.
Please stop saying anything beginning with 'meth' is just meth with added bits.
It's a really odd misinterpretation of the terrible dangers of: methane, Methodists, methanol, Methaemoglobin, methicillin, etc.
