Yes it is. That's why it's they're Schedule II drugs, the category which carries the highest prescripion restrictions of any medications in the United States. (The only thing higher is Schedule I, which are drugs that are banned entirely, like LSD and heroin.) Which is why people that take it w/o a prescription can go to jail for taking them.
I took one of my wife's Adderall's last summer. Don't buy that two cup of coffee bullcrap. I was up for two days and spent my nights with that hummm going through my body I had not experienced since college. As most people on speed, I thought the world was great. That was until I came down and realized I had started about twenty new projects and finished not one......
And this is precisely why it's a Schedule II drug. See, the thing about Ritalin and Adderall is that they have the reverse effect on the brain in those with ADD/ADHD; instead of speeding them up, it allows them to calm down and concentrate. But for plain old abusers, yes, it acts as plain old speed. Which leads me to ask the question: Why were you taking your wife's Adderall?
The other problem is what these people do when they are no longer children and are not on insurance that ponies up speed for adults. A long term amphetamine user who stops taking speed is an ugly scene.
Well, an intelligent parent and/or doctor would prepare for this well ahead of time, in the rare cases where it would actually occur.
(And before anyone tries to start the argument: Yes, lots of people are MISdiagnosed with ADD/ADHD, and no, I do not believe public schools should be able to force kids to take any drugs whatsoever. I'm simply saying Ritalin and Adderall are legitimate medications with legitimate medical uses in those that actually have such diagnoses.
