How to tell if a person is on cocaine.

Cocaine’s effects are intense and brief. There is an initial ‘rush’ of pleasure followed by a slow, then rapid comedown which can be unpleasant. During the high there is a feeling of extra energy euphoria. Users feel more intelligent, wittier and able to mix with others easily.


There may be a perception that work is easier and more interesting and more is accomplished in the same amount of time. 

At the same time energy levels seem improved, appetites are suppressed, so weight loss can occur. Users often claim to feel more at ease and self-confident while on cocaine.

As the drug wears off these feelings begin to disappear and be replaced by an increased irritability and displeasure that can increase for hours. A desire to return to the feelings of confidence and power leads to more cocaine use. 

Look for these changes in mood and activity as indications of drug use, particularly cocaine and other “uppers”.


Below are some common indications that a person is using cocaine. Any of these can occur without any drugs being involved. The more symptoms present, the greater the chance that drugs are involved, primarily cocaine with this set of signs.
