Users of cocaine use the drug to reach a “high”. The “high” is described as a euphoric and energetic state where you become hypersensitive to stimuli and achieve a state of mental alertness. In this state people will become talkative, hypersensitive to stimuli (sight, sound, and touch), and experience a decrease in the need for food and sleep.
Long-term effects on the body can vary from person to person depending on how heavy the dosages they take each time they use cocaine. Some can experience minor effects such as: anxiety, mood swings, increased energy and alertness, restlessness, and irritability. Others can experience some more major side effects such as: depression, hypertension, damage to nasal passages, constriction of blood vessels, vasoconstriction of blood vessels in the brain, loss of smell, chronic runny nose, irritability, and hallucinations.
The length of time the individual uses cocaine can last in the body can range from two days in the blood and saliva, to years in the hair. The effects of the drug can be felt within 5-10 seconds with smoking or intravenous use, 3-5 minutes when snorting the drug, and 10-30 minutes when ingested orally.
