First of all a Public Service Announcement: Don't do/sell drugs - its bad. Now on to the lecture part of the answer: Crack Cocaine only gets you high for about 15 minutes. Pound for pound (or gram for gram) Methamphetamine gives you a much larger bang for your dollar. We are talking on the order of 4 to 8 hours (depending on the quality of the product and how you do it). Further if you IV use meth its like sex - but sex with 100 people at the same time for like 4 to 8 hours. And the rush compares to sex in a way. If Sex was being hit in the face with a baseball bat - Meth is like being totally body slammed with a big rig going 65 mph. Freebasing is fun and all, but lets face it - if you are doing or selling drugs Meth is where it is at. Crank (not crack) is cheaper in the long run. Although I would rather you did not sell or use, I would prefer that you do it frugally - either way both Crack and Crank pretty much fuck you over in the long run. But crank is a lot more fun in the process! Now on to the technical part of this answer: Adding Baking powder to cocaine leads converts cocaine into methylbenzoylecgonine (I'll let you look up the big word I's spelt it korecktly -lol). The ratio is 2:1 2 parts baking powder 1 part cocaine. Or if you prefer it is 2/3 baking powder 1/3 coke. And to finish up lets look at the legal end of this. The ways the laws are written now days, users with 'cut' product get more time than big time dealers/manufactures with 'pure' product (meth or coke). Currently the average for the crime is 8 years. (On average per capita) Also if you are doing the process of cutting or freebasing anything like that you are now a manufacturer yep even if you cut a bit of speed with half an aspirin) They will slap on things like conspiracy to sell, conspiracy to manufacture - on top of the possession and most likely internal possession (a nifty way they can hit you twice on being high) along with being under the influence (in a car, on public, while driving, blah).
