I have been taking a low dosage eg 2.5 mg of selegiline a day, and had a concern about the metabolite of selegiline that might give a false positive on a drug screen. I have not been able to see my physician for a script for the drug, though I will shortly . Anyway ... I drive for a living and have to deal with the reality of submitting a urine sample for drug testing in the chance of a vehicle accident. I'm not sure such a low dosage is even a cause of concern , but it's another thing to think about.
I red today the following in the discussion link of Wikipedia when researching selegiline;

Note the third paragraph.

l-methamphetamine

As of several months ago, the article stated that the selegiline metabolite l-methamphetamine is inactive, meaning that it is minimally psychoactive. Recently the article was edited (I believe by Jclerman) to the current text: "Selegiline is partly metabolized to l-methamphetamine, an active stereoisomer of methamphetamine in vivo".

I believe this is incorrect, as the methamphetamine article states: "L-methamphetamine (also called levmetamfetamine and desoxyephedrine) has nasal decongestant activity and no abuse potential.

>> This is the active ingredient in the US Vicks Inhaler." <<

Also, l-methamphetamine is not produced illicitly for abuse purposes (the most common precursors used result in d-methamphetamine). For this reason I will edit this information to make it clear that l-methamphetamine has little or no abuse potential and the use of selegiline can not result in a methamphetamine-like intoxication. The use of the term 'active' and 'inactive' is admittedly vague and will be changed. --Bk0 (Talk) 18:38, 30 October 2006 (UTC)

L-methamphetamine is orally active, etc., but you need a four times as high dose (compared to d-methamphetamine) to get the same level of CNS stimulation, meaning you need several 10mg tablets of selegiline to get the same effect as a single 5mg tablet of desoxyn (or even dexedrine).
Also, l-meth is more peripherally active than d-meth.
It is quite possible to get the CNS stimulant effect from it, particularly since the MAOI activity will potentiate it, but it requires a fairly high dose, and you'd have to be pretty desperate. There's a million other things one can abuse. As readily available as meth is in Japan, I fail to see why they'd latch onto something like l-dep... Zuiram 17:12, 6 February 2007 (UTC)

Levomethamphetamine

OTC
Routes Nasal Inhalation

Levomethamphetamine (other names: l-desoxyephedrine, l-methamphetamine, levmetamfetamine ) is the l- stereoisomer of methamphetamine, a sympathomimetic vasoconstrictor which is the active ingredient used in some over-the-counter nasal decongestants. The common brand-name for levmetamfetamine in the U.S. is the Vicks Inhaler. In the U.S., the name was converted to levmetamfetamine from levo-methamphetamine to lower the risk of abuse of the decongestant preparation.



Sweet, now no more worries about what to say when asked, are you taking anything when signing off on a urine sample- my employer is not the most progressive , and may look into all the details they can. Sniff.
