Drug Admin Routes
1) Inhaling (smoking)—7-10 seconds: lungs→heart→brain
2) Intravenous injection (via needle into vein)—15-30 seconds: bloodstream→heart→lungs→heart→ rain
3) Intramuscular injection (via needle into muscle); subcutaneous injection (via needle under skin)—3-5 minutes: absorbed into bloodstream→heart→lungs→heart→ brain
mucosal absorption: a) insufflation, snorting into nose ; b) buccal, placing next to gums; or c) sublingual, placing under tongue—3-5 minutes: absorbed through mucous membranes into bloodstream→heart→lungs→heart→brain
4) Mucosal absorption, rectal or vaginal—10-15 minutes
5) Ingesting, oral administration—20-30 minutes: stomach→small intestine→liver→heart→lungs→heart→brain
6) Transdermal, skin patch—1-2 days…slow sustained delivery of drug, rather than fast delivery of large amount
