Cocaine use stimulates the brain and central nervous system, and can result in a variety of effects. The effect that cocaine has on an individual depends on a number of factors. These include:

•         how much cocaine is taken
•           the method of use
•           the form and purity of the cocaine
•           the height and weight of the user
•           the user’s current physical and mental health status
•           the user’s previous experience with cocaine (i.e. new user vs frequent user)
•          whether other substances (alcohol, tobacco, medications, or other illicit drugs) are used at the same time as cocaine.

Short term effects of cocaine use can include feelings of excitement, happiness, and confidence. People may feel confident, energetic and alert, and have less need for food or sleep. Negative short-term effects include rapid breathing and increased body temperature, heart rate and blood pressure. Some people who use cocaine may behave erratically or aggressively, and may feel restless, irritable, or anxious and paranoid.
