> I don't think I can say that there is much of a pattern between ADHD and overeating, just based on how easily I can predict if someone is overeating or not if I know they have ADHD. That is, it would be a coin toss. Person you responded to suggested P( overeating | undereating ) as opposed to your P( overeating ). I expect the effects of those two conditions would tend to cancel each other out in observations. > As seen in studies where people that start lisdexamfetamine (ADHD medication common in the EU) have a huge reduction in actual amphetamine abuse. Perhaps I misunderstand you but lisdexamfetamine _is_ an amphetamine. That reads like saying that people prescribed an opiate exhibit reduced opiate abuse. It seems either tautological (not abuse because permitted) or obvious (cooperative supervised use reduces bad things happening) or perhaps related to drug safety (A simply being safer to use than B). |

Lisdexamfetamine is not amphetamine—not chemically, not in terms of its half-life, not in subjective experience, and not in any study that tracks behavioral or long-term effects. At best, it's a prodrug of an enantiomer of amphetamine. You are also mistaken about the study. Reading even the abstract would clear that up for you.
Let me clean up the unnecessary, convoluted language before I answer: Q: Does it stop being called "abuse" once a doctor prescribes it? A: No. The prescription stopped hospitalizations due to amphetamine overdose.
Q: Is it simply safer to use drugs with a doctor's help? A: That was not answerable based on the study's design. It is also not a useful question to ask in this context, since it's comparing apples and oranges. Some of the worst cases of drug abuse are created and maintained by doctors. However, taking drugs collaboratively with a doctor is probably safer on average than getting them from random webpages.
Q: Is this specific amphetamine safer than others? A: Yes, as is the case with any substance we ingest. You can quibble over the details, but beer is safer than hard liquor. Likewise, different medications in the same category or receptor affinity group have different LD_{50} doses (the ratio of the clinically effective threshold to the threshold where 50% of subjects would die).
