Drug precursors, also referred to as precursor chemicals or simply precursors, are substances used to manufacture illicit drugs. Most precursors also have legitimate commercial uses and are legally used in a wide variety of industrial processes and consumer products, such as medicines, flavourings, and fragrances.
In chemistry, a precursor is a compound that participates in a chemical reaction that produces another compound. In biochemistry , the term "precursor" often refers more specifically to a chemical compound preceding another in a metabolic pathway , such as a protein precursor .
Precursor (chemistry), a compound that participates in the chemical reaction that produces another compound; Precursor (physics), a phenomenon of wave propagation in dispersive media; Precursor in the course of a disease, a state preceding a particular stage in that course; Precursor cell (biology), a unipotent stem cell

Anethole is an inexpensive chemical precursor for paramethoxyamphetamine (PMA), [31] and is used in its clandestine manufacture. [32] Anethole is present in the essential oil from guarana, which has psychoactive effects typically attributed to its caffeine content. The absence of PMA or any other known psychoactive derivative of anethole in ...
Ibogaine is a psychoactive indole alkaloid obtained either by extraction from plants in the family Apocynaceae such as Tabernanthe iboga, Voacanga africana, and Tabernaemontana undulata or by semi-synthesis from the precursor compound voacangine, another plant alkaloid. [1] [2] The total synthesis of ibogaine was described in 1956. [5]

Drug nomenclature is the systematic naming of drugs, especially pharmaceutical drugs.In the majority of circumstances, drugs have 3 types of names: chemical names, the most important of which is the IUPAC name; generic or nonproprietary names, the most important of which are international nonproprietary names (INNs); and trade names, which are brand names.
