Ok, so I've found myself in a situation where I have an abundant supply of cocaine. Anywho, I want to try cooking some crack out of say a half gram to start just to experiment. My question is what method usuall produces the purest/most potent crack the ammonia (ammonium hydroxide) or baking soda (sodium bicarbonate) method? I was thinking about using the ammonia method from here: http://www.bluelight.ru/vb/showthread.php?t=394052 but, without the optional additional step of using ether for obvious reasons. So what are your guys' thoughts?
