Lol, I bought methamphetamine from Walmart for the low, low price of $3.85

Vicks Vapor Inhaler.  Active ingredient:  levmetamfetamine.
 I read it out loud and was like lolwut.

Wiki'd: 

Levomethamphetamine (other names include l-methamphetamine, levodesoxyephedrine, l-desoxyephedrine, levmetamfetamine), is the levorotary (R-isomer) of methamphetamine. Levomethamphetamine is a sympathomimetic vasoconstrictor which is the active ingredient used in some over-the-counter nasal decongestants including Vicks Vapor Inhaler.

Chemistry

Levomethamphetamine affects the sympathetic nervous system but has little activity in the central nervous system, so it is not thought to possess an addiction potential anywhere near that of racemic methamphetamine or dextromethamphetamine. Among its few physiological effects are the vasoconstriction that makes it useful for nasal decongestion.^[1]

Side effects

When used as a nasal decongestant, levomethamphetamine has potential side effects resembling those of other sympathomimetic drugs used for the same purpose; these effects include hypertension (elevated blood pressure), tachycardia (rapid heart rate), nausea, stomach cramps, dizziness, headache, and tremors.
