M Kat 

M Kat is a nickname for Mephedrone, also known as 4-methylmethcathinone (4-MMC), is a stimulant and entactogen drug of the phenethylamine, amphetamine, and cathinone chemical classes.

Mephedrone is reported as causing effects described as a cross between those of methamphetamine and MDMA ("Ecstasy"), producing euphoria, stimulation, and empathy. It generally sells for a higher price than MDMA but is cheap to produce meaning that manufacturers are making "huge amounts of money" from selling the drug

Man, I snorted a ton of M Kat last night, i was off my tits.

M Kat 

A street name for the drug Mephedrone which is a synthetic drug which began to grow in popularity in 2008 in the UK when the drug was still legal, then in 2010 the government it was scheduled a class B drug. The drug produces similar effects to cocaine and amphetamines, but it's much worse and the comedown is fucking horrible.

Whatever you do, don't touch M Kat, it will not be good in the long run. I know first hand.

kate e m 

the prettiest and sweetest girl ever. the funniest person who will always make you laugh. the type of person who will dance randomly and who’s smile lights up a room. she’s shy when you first meet her but opens up soon after. so pretty with long brown hair and blue grey eyes. she’s insecure but literally the prettiest person at her school. it’s not just her looks that are so great. she’s amazingly smart and doesn’t skip class to be cool. she puts in all her effort into everything she does- from relationships to academics. in addition to this, she’s an amazing athlete. she will wake up at 5am if she has to do to get in her weekly mileage, and loves the feeling of being in the gym. kate is the sweetest girl ever, and is a beam of light. she lights up any room she is in, and everything’s better with her. i could stay up until 2 am texting her. she is the best girl ever and honestly a baddie. i love kate.

“bro did you see that beautiful girl gawd damn”

MKAT 

A new legal drug many teens use, like coke it's snorted or smoked and looks almost identical to it, although it's actually good plantfood.
The drug gives a short rush and can affect eyesite, mindset and can make the user feel like shit for the coming days. Best kept for the rubber green plant in the corner of your bedroom.

"Dude i got some mkat for the weekend!"

"Awesome man, my plant loves that shit! Got any real drugs for us though?"
