Plastics have even been introduced into our medicines.   As far as I can tell, liquid cough medicine of the Robitussin type, containing only dextromethorphan (DXM) and no other active ingredients, has all but disappeared from pharmacy shelves.  Although you can still get single ingredient DXM in liquid form, it is of the Delsym type, and contains microscopic plastic beads as part of its extended release mechanism.  Moreover. it is much more expensive, on the order of $10 - $14 per (plastic) bottle, versus $5 - $7 for the Robitussin kind.
