K pin 

A slang term for the schedule 4 benzodiazepine, Klonopin. It is sought after for its euphoric effects similar to having smoked weed and drinking a few beers. Its effects can last for up to 40 hours, so it will keep you crunk all weekend if you want. At high doses (+1mg) it causes severe anterograde amnesia and ataxia.

My friend has anxiety problems and was prescribed K pins which he sold me for $10/pill. It's like burnin' a g of KB and taking a few shots, good shit.

K-pins

Street name for clonazepam (brand name: klonopin). Basically the same potency of xanax but triple the half life making your usual xanned out experience longer acting or in my case not feeling like the world is collapsing 24/7. 0.5mg kpin = 10mg valium. kpins are bad ass and I suggest trying them but don't use them or opioids chronically unless you have a prescription in which case its fine because you have a solid source. Oh yeah and don't rapidly stop off kpins or xanax or other benzo's unless your like full blown seizures, double the anxiety you had before your doctor put you on the drug and of course the DT's like some alcoholic and other weird stuff.

Ever since I was introduced to benzo's I learned that pharmaceuticals aren't just sugar pills and that there are effective drugs....

k-pins are a life saver for people with chronic anxiety that have finally realized SSRI's are a pile or platypus shit for anxiety.
