Cocaine is a white powder. It can be snorted up the nose or mixed with water and injected with a needle. Cocaine can also be made into small white rocks, called crack. Crack is smoked in a small glass pipe.
Cocaine speeds up your whole body. You may feel full of energy, happy, and excited. But then your mood can change. You can become angry, nervous, and afraid that someone’s out to get you. You might do things that make no sense. After the “high” of the it wears off, you can “crash” and feel tired and sad for days. You also get a strong craving to take the drug again to try to feel better.
