In psychology, a rush is an , state of euphoria.
A wide variety of recreational drugs are commonly capable of such an event. These drugs include, but are not limited to, opioids (particularly heroin) and psychostimulants (particularly methamphetamine and cocaine).

Intravenous injection is the fastest route of administration, causing blood concentrations to rise the most quickly, followed by smoking, suppository (anal or vaginal insertion), insufflation (snorting), and ingestion (swallowing).
