How Cocaine Affects Your Brain And Body

Cocaine Affects Your Brain And Body

The effects of cocaine only take seconds to kick in. After a hit, the cocaine will enter your bloodstream and head to your brain. It blocks your brain's ability to absorb the pleasure hormones serotonin and dopamine. Without anywhere to go, these hormones build up in your brain. This will dilate your pupils and generate an intense feeling of euphoria. It can also make you feel energized, talkative, alert and reduces appetite in some users. But that's just the beginning, cocaine use can dry out your nasal passage and cause nosebleeds. It also constricts your arteries making you feel warm. This raises your heart rate and blood pressure and in extreme cases can cause a heart attack. The high from a single hit will last anywhere from 5 to 3o minutes.
