Speed heeft wel meer kleuren tegenwoordig...
RED: The product was made from pseudoephedrine, and the red coloring of the tablet was not adequately washed away (it is difficult)
ORANGE: Ephedrine sulfate was used, and some of the sulfate was reduced to sulfur.
PURPLE: Iodine from a phosphorus-iodine reaction was not washed out.
GREEN: Copper (or other metallic) salts somehow made their way in to the mixture, probably due to the reaction vessel used in the manufacture.
BROWN: Oxidized red coloring (see above), or tablating agent was present in the reduction.
Sometimes "speed" is present as waxy rocks that almost seem wet, but do not dry out
Perfetine is volgends mij gewoon methamphetamine, in pil vorm.
