Remmend signaal
Stimulerend signaalBlood circulation is a continuous process.
The routes taken by drugs through the body may vary. If drug molecules are ingested by smoking, some of them go almost directly to the brain.
Others may travel from the lungs via the heart directly to the kidneys and be excreted there into the urine. Those molecules never reach the brain.
