K2 

K2 is herbs sprayed with JWH compounds which are synthetic Marijuana like JWH-018 and JWH-200. Ever since the government banned the safer JWH compounds, K2 was sprayed with stronger and more dangerous compounds. K2 turns your nails black now and can kill you. Kratom and Weed doesn't kill you. K2 kills! Weed and Kratom are legal now and much safer than K2!

Kevin (hooked on K2): This K2 is awesome.
Stan: Kevin, your nails are black.

K2 

a currently completely legal drug in the united states that looks a lot like potpurri but gives out effects very similar to marijuana, sometimes called roses. It is actually synthesized THC but does not come up on a drug test.

"K2 is legal in kansas, but the dumb-fuck government has to ruin everything for everyone, like, if a bill to save babies for $5 dollars a year total comes along, it takes them 19 fucking cunt months to pass the fucking bill but when K2 comes along and doesn't hurt any-fucking-body, it takes them 2 hours to pass the bill.... i fucking hate the government"

The Karakoram is a great mountain system. K-2 in Northeast Pakistan is the highest mountain in the Karakoram range. It is the 2nd highest mountain in thw world. It is known as "The Killer Mountain". Reportedly it is much more difficult to climb than Mount Everest.

Awakening to a complete whiteout and vicious winds, Parmentier radioed base camp by walkie-talkie that he was descending; but with the fixed ropes and all traces of his companions' footprints buried by fresh snow, he soon became lost on the broad, featureless south shoulder of K2.
