Xyathone
this chemical was used in the production of medicinal and recreational drugs on the planet Ord Cestus, during the last decades of the Old Republic. It was a stable compound primarily used to reduce the concentration of the pure drug, allowing manufacturers to reduce the potency of each dosage. Xyathone was also used to cut illegal drugs, allowing pushers to charge more credits for a slightly inferior product. To the discerning individual, Xyathone had a distinct odor that was nearly masked by more powerful drugs.
