Document Summary

Onset of effects is faster than it is for oral administration: absorption through mucous membranes into the bloodstream occurs rapidly, bypassing the liver. Drawback associated with intranasal drug use includes nasal necrosis, or death of cells in the septal region. Drug is delivered directly into the bloodstream: results in a rapid onset of its effects than does with oral administration or with other means of injection. Irritating material may be injected this way, because blood vessel walls are relatively insensitive. Risks: veins may become damaged over time, blood-borne diseases spread easily. Injection under the skin: also known as skin popping . If the material injected is extremely irritating to the tissue, the skin around the site of injection might die and be shed. Larger volumes of material can be deposited in a muscle. Onset of drug effects is rapid because the capillary walls are accessible in the lungs, and the drug thus enters the blood quickly.
