Drug & Cocaine
Cocaine is a strong central nervous system stimulant. Physical effects of cocaine use, including crack, include constricted blood vessels and increased temperature, heart rate, and blood pressure. Users may also experience feelings of restlessness, irritability, and anxiety.10
Smoking crack delivers large quantities of the drug to the lungs, producing effects comparable to intravenous injection. These effects are felt almost immediately after smoking, are very intense, but do not last long.11 For example, the high from snorting cocaine may last 15–30 minutes, while the high from smoking it may last 5–10 minutes.12
Evidence suggests that users who smoke or inject cocaine may be at even greater risk of causing harm to themselves than those who snort the substance. Cocaine smokers may suffer from acute respiratory problems including coughing, shortness of breath, and severe chest pains with lung trauma and bleeding.13
An added danger of cocaine use is when cocaine and alcohol are consumed at the same time. When these substances are mixed, the human liver combines cocaine and alcohol and manufactures a third substance, cocaethylene. This intensifies cocaine's euphoric effects, while also possibly increasing the risk of sudden death.14 Most cocaine-related deaths are a result of cardiac arrest or seizures followed by respiratory arrest.15
Cocaine is a powerfully addictive drug. A tolerance to the cocaine high may be developed and many addicts report that they fail to achieve as much pleasure as they did from their first cocaine exposure.16
During 2002, emergency departments (ED) nationwide reported 42,146 crack mentions to the Drug Abuse Warning Network. Crack accounted for 21% of the total cocaine mentions during the year. The number of crack ED mentions has increased from 33,789 in 1995, but has decreased from 46,964 in 2001.17
