• Can be snorted, dissolved in water and injected into veins
• High lasts 30 – 45 minutes

Crack is chemically changed cocaine that can be smoked, or inhaled:
• It is more addictive due to it’s shorter half-life
• The rapid feeling of euphoria followed by a quick loss make it highly addictive

Short-term Effects
• Rapid breathing and heart rate, dilated pupils and sweating
• Euphoric, energetic, alert, enhanced sociability, loss of appetite

Dependence Potential
• Chronic use results in tolerance (the need to take more cocaine to feel the same effects)
• Can produce very powerful psychological dependence, leading to extremely compulsive patterns of
abuse, and a constant craving for the drug
• Due to the chemical changes in dopamine caused by cocaine use; when cocaine use is stopped the
dopamine levels are insufficient creating an inability to experience pleasure, and potentially leading to
chronic/severe depression. This effect can last anywhere from 6 to 18 months.
