Dopamine is a neurotransmitter which is often a pleasure producing chemical. Drugs can either act as agonists or antagonists on receptors, which impact the secretion of this rewarding chemical. As a result, drug users use this in order to achieve the euphoria. Eventually, it takes more and more of the drug in order to achieve the same level of euphoria. This is the beginning of addiction.

For example, methamphetamines are an extremely powerful drug, which can lead to the chemical addiction as mentioned above. The withdrawal symptoms can have severe physiological symptoms as well as lead to death due to the lack of medication. This lead to the production of a medicine known as methadone, which is a pharmaceutical which can keep the side effects from methamphetamine occurring, but itself is addicting. In addition, the war on drugs has been occurring for many years, but illegal drugs still are being used and will still make their way onto the streets. As long as there are buyers and sellers, the drug trades and cartels will continue to exist as they find better and more covert ways of initiating their drug transactions. ...Download file to see next pagesRead More
