Smoking crack



I want to know how can i tell when some one is smoking crack what is the sign; what do they do? and how they act?


Crack is a form of cocaine, which is a central nervous system stimulant. How a person acts when taking crack depends on a number of things, including the dosage, pattern, and duration of use.

Intoxication with moderate amounts of crack may produce the following behaviors:

In very high doses, individuals may show signs of

Withdrawal from crack may cause a wide range of symptoms including a "crash" period that includes depressed mood, anxiety, agitation, and intense drug craving. The crash period is followed by an intermediate withdrawal phase that includes symptoms of fatigue, a loss of physical and mental energy, and decreased interest in the environment.

Remember that each person who uses crack may react to it in a slightly different way. There is really no way to tell "for sure" that a person is using any drug, including crack, simply by observing the person.

Depending on whether you are observing an individual who is "high" on crack or who is "coming down" off crack, the symptoms will be very different. If you observe very erratic high and low symptoms that are not "normal" for the person, these symptoms may be the result of cocaine use. However, there may also be other causes of this behavior (such as bipolar disorder). The only way to know for sure is to perform a drug screen, which would reveal cocaine in the individual's urine.
