Which route involves substances being inhaled into the lungs, such as through smoking or huffing?

Explanation:
Inhalation is the route where substances are breathed into the lungs. When people smoke or huff, the drug-containing vapor or fumes enter the lungs and quickly pass into the bloodstream through the alveoli, leading to a rapid onset of effects. This fast absorption distinguishes inhalation from other routes. Snorting delivers through the nasal mucosa, transdermal goes through the skin for slow release, and buccal administration uses the cheek or gum tissues, also with slower absorption compared to inhalation.
