Hitting an artery can be painful and dangerous. Arterial blood travels away from the heart so whatever is injected goes straight to body limbs and extremities. Injection particles get stuck in blood capillaries and cut off circulation. This can result in a lack of blood flow, eventually causing the tissue to die.
