Term used by law enforcement to describe individuals (usually addicts), who find and/or gather the raw materials for their dealer to make more
drugs.
Most commonly used in the methamphetamine trade, where "smurfers" visit pharmacies and purchase small quantities of
cold/flu tablets to provide to a maker ("papa
smurf") of the drug.
Alice: See that
girl? I always see her at the
local chemist, purchasing Sudafed.
Diane:
Really? She's probably a smurfer.
