Intranasal or snorting

When snorting a drug you feel the effect after a few minutes. So this is a very quick way of taking it. The nasal mucosa contains many small blood vessels and this is how the drug is absorbed into the blood. The blood is then pumped around the body by the heart and ends up in the brain. So the drug does not go straight up through your nasal mucosa to your brain. It always goes through the heart to the brain.

Regular snorting can irritate and inflame the nasal mucosa. In extreme cases, this leads to chronic colds or loss of sense of smell and taste.
