Which symptom is commonly associated with cocaine abuse?

Cocaine abuse is known to have several physical manifestations, and frequent nosebleeds are particularly associated with its use. This symptom occurs because cocaine is often snorted, leading to irritation and damage to the nasal passages. The vasoconstrictive properties of cocaine can cause blood vessels to become constricted, and prolonged use can result in the breakdown of the nasal tissue, which may bleed easily.

Other symptoms that can be linked to cocaine use include heightened energy levels, increased alertness, and euphoria, but these are not reflective of physical damage like nosebleeds. Flushed cheeks may occur due to increased blood flow or excited states, while slurred speech and drowsiness are more commonly associated with depressant substances, rather than stimulants like cocaine. Therefore, nosebleeds stand out as a clear and common sign of cocaine abuse.
