Genetic Predisposition
Genetic Predisposition
Genes are thought to be responsible for about half of a persons susceptibility to addiction. We all know that genes are passed down from each parent. In fact, 23 chromosomes are passed down from each parent and given to the child. Genes carry DNA or genetic material, that can have certain diseases that are linked to them. We commonly refer to these as genes that "run in the family." In short, this means that if you have a family history of addiction, you have about a 50% chance of gaining one too, but it is not guaranteed. There are still a lot of other factors that go into addiction for each individual person.
Environmental Factors
Environmental Factors
Things like an individuals upbringing and their environment can increase the likelihood of someone's overall risk of substance use and addiction.
Negative early life experiences such as trauma, abuse, neglect or witnessing domestic abuse causes an adverse effect on the brain development of a child. Being put in a constant fight or flight situation takes a toll on the brain and its development causing behaviors related to addiction like decision-making abilities and impulse control.
Witnessing parents using substances, poor parental supervision, and emotional neglect are also major factors.
Areas with higher crime rates and with low socioeconomic status can increase the risk of drug addiction in an individual. Longterm exposure to these environments leads to impulsive behavior and sensation-seeking which further increases the risk of addiction and substance abuse.
