Cocaine use makes the fighting center in the limbic center hyperactivated, as well as emotional triggers are overstimulated, which makes sense to explain why Jordan slaps his wife and then tries to kidnap his son after snorting cocaine. All this anger and emotion went through him and made him explode. They also claim that cocaine increases the heart rate and narrows the blood vessels, Jordan's physical state showed signs of accelerated heart rate and therefore he would do another line of cocaine. Cocaine was used throughout the film, which meant that Jordan was a compulsive cocaine user. Inaba, Cohen and Pharm (2014) state that in addition to hereditary and environmental vulnerability, such as Jordan's stress case with the FBI investigating him, people use cocaine compulsively to find the first rush they had, cocaine changes the way the brain works and, therefore, makes it more vulnerable to cravings and control symptoms of depression. I think this movie shows every stage of cocaine use. Since he was stressed, so he had to find a way to deal with it, from experiencing symptoms, to resorting to other drugs, to getting in trouble with the law, to finally trying to sober up. What's great about this movie is that it shows something that can happen to someone and it's based on something that actually happened
