Is the adhd medication desoxyn (methamphetamine) effective?

Yes: Desoxyn (methamphetamine) has been found to be effective by the fda.

Real speed: Desoxyn is methamphetamine. Yup the same stuff some truckers and bikers use. Although it is fda approved & can help adhd, it is rarely recommended in the usual array of medication algorithms published for this condition. The reason is it is too easily diverted to illicit use. It is also the most addictive of the adhd medications available. I always look for an alternative before prescribing this.
