I realize that giving L-dopa or similar drugs to people who don't need it would be unethical owing to their side effects*, but given that L-dopa is abused by some Parkinson's disease patients, are there perhaps some reports of similar side-effects/syndrome in non-Parkison's individuals who might abuse L-dopa? I basically want to know whether the drug-induced dopamine dysregulation syndrome can show up in more or less "healthy" (not counting the abuse itself) individuals. I'm aware of course that stimulants (amphetamine, cocaine etc.) can also produce some of the same effects, but these are drugs with a more complex pharmacology.
*Actually, after writing the above, I found out it was given in a fairly recent 2012 study which found no mood effects. It also mentions nothing like dysregulation syndrome being observed in these healthy volunteers. Furthermore, it says that testing higher doses "will be difficult, though, since higher doses of all currently available drugs that selectively augment DA neurotransmission are limited by side effects such as nausea, vomiting, dizziness and drowsiness." So I'm guessing abuse potential in healthy people is nearly nil because of this. Nevertheless, perhaps some accidental poisioning or other odball report exists.
