from what i've read, methamphetamine is almost never prescribed for a.d.d., or anything. and the author of those posts misspelled amphetamine. so, they probably don't know a lot about it. jewish people do profit from a.d.d. / a.d.h.d., though. for example, teva pharmaceuticals is in israel, and is 1 of the main manufacturers of generic ritalin and adderall.
