When someone is on cocaine, they usually have dilated pupils, may speak quickly, and appear restless or have trouble sitting still. On higher doses or after extended binges, cocaine users may also act anxious or even paranoid, being very vigilant of their surroundings and others around them. They may even experience hallucinations. In less extreme cases, a runny nose, constant sniffling and snorting, as well as repetitive touching of the nose can also be signs of cocaine use when combined with one or more other symptoms. Finally, possession of drug paraphernalia which can be used for snorting or chopping cocaine such as straws (often cut to size), rolled up money (sometimes used instead of straws), cards or razor blades (used to break up clumps and make “lines” of cocaine), when packed together as a “kit”, or with visible traces of white powder on them, or combined with physical and psychological symptoms listed above, can also be a strong indication of cocaine use.
