[0:00]Why does cocaine feel so good?Let's try it so you don't have to. As soon as you take it, it floods your bloodstream and starts to tighten blood vessels throughout your body. Your heart begins to race, your blood pressure spikes, and your brain demands more oxygen. Inhaled cocaine can reach your brain within seconds. There, it blocks transporter proteins that normally clean up neurotransmitters like dopamine, serotonin, and norepinephrine. As a result, chemicals linked to motivation and joy build up and keep stimulating your reward circuits. Your brain adapts fast. With repeated use, high dopamine becomes the new normal. Drop below it and you feel anxious and drained. So, you take more to feel okay again. Even a single use can trigger heart attacks or strokes, even in young and healthy people. Long-term use damages the heart, erodes memory, and can reshape your personality. In extreme cases, blood vessels rupture, the brain swells, and death follows fast. Every year, tens of thousands die with cocaine in their system, and the risk is even higher today. Cocaine is often mixed with other, more lethal drugs, so one bump could be your last. We're not here to tell you what to do, but cocaine messes with your entire body, so you should know what it's doing to you.
