What is the method of drug ingestion that involves drawing the substance into the nostril?

• A. Ingestion
• B. Insufflation
• C. Inhalation
• D. Injection

Answer: (B)

The method of drug ingestion that involves drawing the substance into the nostril is known as insufflation. This process typically involves the use of a powder, which is often finely ground, allowing the user to inhale it through the nasal passages. When drugs are insufflated, they are absorbed quickly into the bloodstream through the mucous membranes in the nasal cavity, leading to a rapid onset of effects. Insufflation is distinct from other methods of ingestion. For example, ingestion generally refers to swallowing, which involves the gastrointestinal system and results in slower absorption rates due to the digestive process. Inhalation involves drawing substances into the lungs, typically through smoking or vaporization, which also results in quick absorption but targets the respiratory system rather than the nasal passages. Injection involves delivering substances directly into the bloodstream via syringes, which provides immediate effects but does not involve nasal intake. Thus, the term specifically used for drawing a substance into the nostril for absorption is insufflation, making it the correct answer.
