You are 100% NOT taking meth when you take ADHD stims. The only thing linking the two is the core ingredient which is a methyl-5 molecule, which your body makes on its own.

The drug meth is a synthetic methyl-5 compound with a ton of other nasty crap in it that doesn't exist in ADHD medication.

Like I said, whoever says that is in the same group as the American cheese is almost plastic crowd.

No, the thing linking the 2 is the amphetamine part. Which is the actual stimulant.

The drug meth is actually just methamphetamine - there's no "nasty crap" in it unless the person synthesizing it doesn't refine and purify it well, which is true of basically all chemistry.

A more apt comparison is a strong beer and wine - both technically different things, but both get you drink because of the alcohol ingredient in them. They're both alcoholic drinks.

Same with amphetamines - both are stimulants that have essentially the same effect. That's specifically why they both work in treating ADHD. The only significant difference is one is legal (with a prescription) and the other isn't, which of course means good luck getting it really pure and at the correct dosage. The only other difference is how fast acting / long lasting they are because of that tail molecule, but the part that has an actual effect on people is the amphetamine part.
