Document Summary

Oral is ingesting something, one of slowest routes because goes through gi tract half hour. Inhalation is breathing or snorting or smoking, because once you inhale goes straight to brain. Insufflation, inhaling drugs through the nose, is highly addictive but less addictive than drugs that are injected. Injection- most direct, intravenous means goes right to vein. Fastest can be very dangerous (likely to inject bacteria and unexpected toxins) especially when using an infected needle. Transdermal drug is absorbed through skin, ex. Drug in patch has to be pretty potent, released into bloodstream over several hours: transdermal administration occurs slowly, since the drugs have to be absorbed through the skin before the effects can be felt. Can deliver drugs to your system slowly or quickly: ex: quick delivery - epipen given to someone experiencing an allergic reaction which starts closing airways. Epipen delivers epinephrine quickly and allows airways to open).
