Nasal insufflation (which is also called colloquially "snorting," "blowing," or "sniffing") is a common ingestion method of recreational cocaine powder. This drug coats and is absorbed through the mucous membranes by lining the nasal passages. The desired euphoric effects of cocaine are delayed when snorted via nose by around 5 minutes. This takes place because the absorption of cocaine is slowed by its constricting effect on the blood vessels of the nose.
