There are a myriad of cocaine drug addiction symptoms, both physiological and behavioural. Cocaine has a serious and consequential effect on the brain, as it alters the brain’s ability to absorb the natural chemicals that cause emotional highs and lows, even after only one use. As it blocks these chemicals from the neurotransmitters in the brain, it causes them to build up in between the nerves, which creates the intense feeling of elation, or high. The problem is, after the first high, no subsequent highs ever come close to the same levels of intensity and euphoria. Now that the user is unable to feel natural highs from everyday life, they are dependent on drugs to feel good. Cocaine addicts then need higher doses of the drug, and more and more frequently, in order to enjoy that high feeling. Oftentimes, they will mix cocaine with alcohol, or other drugs, in an attempt to experience a high like that first one. These attempts get more and more desperate, making all of the symptoms increase in turn.
Of course, the longer the individual is addicted to cocaine, the worse the symptoms will become. People who engage less frequently will have less intense symptoms, however the effects to the brain begin with the first use.
