   • 2013 August 10, “A new prescription”, in The Economist, volume 408, number 8848:

     As the world's drug habit shows, governments are failing in their quest to monitor every London window-box and Andean hillside for banned plants. But even that Sisyphean task looks easy next to the fight against synthetic drugs. No sooner has a drug been blacklisted than chemists adjust their recipe and start churning out a subtly different one.

3. (medicine) Produced by synthesis, thought to have the same effect as its natural counterpart, but chemically different from it.
4. Artificial, not genuine.
5. (grammar) Pertaining to the joining of bound morphemes in a word (compare analytic).
6. (linguistics) Of a language, having a grammar principally dependent on the use of bound morphemes to indicate syntactic relationships (compare analytic).

However, especially in medical contexts, synthetic is most often meant to denote molecules (active ingredients in drugs) that are chemically different from the natural substance on which they are based.
