there is no such thing as "pure Coke" in powder form. even the extract from the coca leaf itself is not pure..The process by which the extract is refined has been improved over the years..but keep in mind that the extract goes through 3 different processes before it becomes cocaine hydrochloride or "powder" (about 85% cocaine, 15% chemical by products and hydrochloride salts). having said that i can assure you that a 1 kilo brick can become 2 kilos and the average dealer would never know...let alone the average user.. what you buy on the street depends on the weight your dealer buys... if he's buying multiple ounces youre gonna get decent quality...if he's small time he has to cut it so he can make a good profit.. keep in mind that a kilo right off the boat will run at least 17k so if a local guy is selling for less than 22k hes cutting it.... and for all you people who think you're getting good stuff cause its all one peice... think again.. i can show lotsa different ways to rerock coke...I can even make that shiny oily fish scale that everyone raves about... this is all illegal so i would never do it... nor am i implying that i ever have
