Well I'm not a chemist so I'm not going to argue on the finer points of amphetamine manufacture, but I do have some knowledge of chemical theory and what I said is what I understand from people who are chemists. Plus, what you say above doesn't make sense for several reasons: 1. Why would the chemists spend more time & money performing an additional step to the procedure to take a good product and basically degrade it to a weaker product which is sticky and more difficult to handle with no apparent advantages from doing so? The a reason for freebasing cocaine is so that it can be smoked. You can't smoke base phet so there's no point. 2. I can't see the criminal masterminds really giving a damn over how easy their product is to cut once it's left their hands. 3. Paste is very easy to cut - you either just mix glucose with it as it is or you let it dry out first then cut it - no problem there (I know, I've done it myself). 4. Paste is way, way less potent than the proper sulphate powder in the early eighties - a gram would last a week, and even at the height of my 'speed freak' days I wouldn't get through more than 3g a week. With paste, you can easily get through an 1/8 (3.5g) in a night - you need a teenth to even get a decent buzz - you can't tell me this is the same stuff. 5. Base amphetamine (or many other chemicals) is not a stable molecule - the sulphate group is added to complete the electron shells therefore making it less reactive. Base is much more reactive so will combine with the body's chemistry in undesirable ways thus giving rise to unwanted side effects e.g palpitations, dizziness etc. which can detract from the 'high' or desirable effects. It also oxidises much quicker so goes off very quickly, which is why drying it out gives such variable results - IME making it much less potent. This is why most pharmaceuticals are in the salt form - typically hydrochloride, Phosphate & Sulphate. Also, the salt form is much more easily absorbed through the mucous membranes than the base (think of putting salt on a slug), which is why sulphate gives you a proper rush and base just gets stuck up your nose. Anyway, fuck all that, let's just make some meth..
