Cocaine is a powerful stimulant that can have serious effects on the human brain. One of the most common side effects of cocaine abuse is headaches. Cocaine works by increasing the levels of dopamine in the brain, which can lead to feelings of euphoria and pleasure. However, it can also cause blood vessels in the brain to constrict, leading to headaches. In addition, cocaine abuse can result in dehydration and electrolyte imbalance, both of which can contribute to headaches. Ultimately, cocaine abuse can cause a wide range of problems, including headaches. If you or someone you know is struggling with cocaine abuse, it is important to seek professional help.
