Cocaine and crack can be taken orally, through the nose (snorted), injected with a syringe or, in the case of crack, through inhalation of the fumes from heating it. The work cocaine refers to the drug in a powder form (cocaine) and a crystal form (crack).
Short-term effects: Cocaine causes a short-lived, intense high that is immediately followed by the opposite, intense feelings of depression, edginess, and a craving for more of the drug. People who use it can experience greatly increased heart rate, muscle spasms, and convulsions.
Long-term effects: In addition to those effects already mentioned, cocaine can cause irritability, mood disturbances, depression and hearing hallucinations. Tolerance to the drug develops so that more is needed to produce the same “high”.
Risks: The drug can make people feel paranoid, angry, hostile and anxious, even when they aren’t high. A person can overdose from his first try.
