Semisynthetic Drugs Pharmacologists often take refined natural drugs and change their chemical structures to vary their properties. A very simple change is to combine an insoluble drug from a plant with an acid to make a water-soluble salt. In this way the "freebase” form of cocaine, which is usually smoked because it will not dissolve, is turned into cocaine hydrochloride, a water-soluble compound that can be inhaled or injected. A slightly more complicated transformation is the addi­ tion of chemical groups to a natural drug molecule to make it stronger.
