Yes obscure might not have been the best fit. But it is a really old treatment for ADHD and is not used much now days. A lot of that has to do with patents and no pharmaceutical companies pushing it. Others have to do with the fact that it is pharmaceutical methamphetamine.

It's a little much to go over in text, but this guy:

gives a really good overview of the differences in the chemicals. He does not go into methamphetamine (Desoxyn) but I did a lot of research on it as well when I was looking to find the most effective treatment for myself. Having taken Desoxyn, Adderall and Dexedrine, I find half the dose of Desoxyn equals a similar dose of Adderall so 15mg = 30mg, with a lot less of the physical side effects (methamphetamine crosses the blood-brain barrier easier and has an affinity for the CNS over the PNS). To me Desoxyn and Dexedrine are similar but Dexedrine required a slightly higher dose, and did not create quite the clearheaded-ness that Desoxyn does.
