  1. How do Drugs get in the Body?

  2. 1) Who will experience the greatest effect of the drug? • Individuals whoinject the drug into a vein will experience the greatest effect from the drug as these individuals will have a higher concentration of the drug in the brain.

  3. 2. Who will experience the quickest effect from the drug? • The person who inhales the drug will experience the quickest effect from the drug (assuming the person inhales the whole 100 mg).

  4. 3. Who will experience the least effect from the drug? • The person who ingests, or swallows, the drug will experience the least effect.

  5. 4. Who will experience the slowest effect from the drug? • The person who ingests, or swallows, the drug will also have the slowest effect.

  6. 5. Tobacco smokers can use nicotine patches to help them quit smoking. The nicotine patches help the smoker slowly lower the amount of nicotine that enters the body. How does the nicotine in the patch enter the body? • Nicotine would enter the body by absorption through the skin.

  7. 6. Explain why the different ways of taking drugs cause different responses. a) Inhalation • Drugs that are inhaled (smoked) reach the brain the most quickly. • Inhaled drugs are absorbed into the blood in the lungs and then pumped to all parts of the body including the brain via systemic circulation

  8. b) Injection • Rapid increase in the drug level in the brain but slightly slower than inhalation • Drug goes first to the right side of the heart then to lungs (pulmonary circulation)  back to the left side of the heart finally to the brain and body(systemic circulation)

  9. c) Snorting/ snuffing • Absorption through the skin or mucous membranes. • Slower response because the drug has a an even longer path to travel before being circulated to the brain and body.

  10. d) Ingestion • Slowest onset of response • The drug goes into the digestive tract and then must pass through the walls of the stomach and intestine to enter the blood capillaries.
