MCAT
An amphetamine-like drug which has gained high popularity in recent years due to its relatively easy synthesis and readily available ingredients.

It is most often insufflated (snorted) or bombed (wrapped in cigarette paper and ingested orally).

People on it are dirty horrible skanks that need to get a grip, you'll either be trying to fight someone because your so out of it you dont know what youre doing, or you'll try to shag everything you see.

It makes you look like a walking corpse after prolonged use and people on it come up with all sorts of stupid excuses as to why their noses are running and they have red eyes after snorting it. Truth is, it's like snorting fire, its not a cold or an allergy.
Guy: She's got red watery eyes and she keeps sniffing.
Guy 2: Yeah she's on MCAT again, she says it's a dust allergy, last week it was a cold but she's just addicted to snorting that crap.
