Similar to amphetamines, cocaine induces heightened alertness, elation, self-confidence and feelings of overall happiness. These euphoric effects are accompanied by increases in blood pressure and heart rate, but also result in a loss of appetite and insomnia. The high produced by snorting, the most common method of consuming cocaine, takes a little over a minute to reach the brain, which peaks within 5 minutes and can last up to 20 minutes before a new dose is required to start the process all over again.
