Methamphetamine Addiction: Biological Foundations, Psychological Factors, and Social Consequences

“As with heart disease or diabetes, there’s no one gene that makes you vulnerable,” Koob says. Addiction is a condition in which something that started as pleasurable now feels like something you can’t live without. Doctors define drug addiction as an irresistible craving for a drug, out-of-control and compulsive use of the drug, and continued use of the drug despite repeated, harmful consequences. Opioids are highly addictive, in large part because they activate powerful reward centers in your brain. Scientists at the Indiana University School of Medicine have identified an overlooked area of the brain that could play a crucial role in determining the likelihood of relapse for individuals with drug use disorders, even after extended periods of withdrawal.

One model posits that there are “allostatic” changes (that is, alterations in baseline set-points) that may occur upon repeated exposure to drugs or stressors [97, 100]. Such exposures may differentially influence specific neural structures, with initial involvement of the mesolimbic dopamine system progressing to the nucleus accumbens, prefrontal cortex and extended amygdala with continued drug exposure and increasing compulsivity (see figure 4 in [41]). Such environmental influences may come from multiple domains salient to adolescents including parents, peers, school, church, and extra-curricular involvement, to list several, and may include positive pro-social influences and negative ones such as bullying or other forms of abuse. Over the past several decades, substantial research has investigated the biological factors leading to and resulting from addictions [1, 2].

Key Elements of the Biological Model of Addiction

As people with SUD often have co-occurring mental health conditions, treating them together rather than separately is generally better. Treatment is highly individualized — one person may need different types of treatment at different times. Adolescents are especially at risk for developing SUD due to exposure. Adolescents who start using http://kilowattsecond.ru/t/674892 substances early are more likely to develop an SUD. About 70% percent of people who began using at age 13 have an SUD compared to 27% who started at age 17. With physical dependence, your body has adapted to the presence of the substance, and withdrawal symptoms happen if you suddenly stop taking the drug or you take a reduced dosage.

• Genetics and biology are a part of the picture—albeit not the entire picture.
• Consistent with this notion, adolescents and young adults as compared to children and older adults have high rates of addictions [11].
• Consistent with a role for rewarding effects of drugs in addictive processes and a role for dopamine in this process, an incentive salience model of drug addiction proposes that “liking” a drug may be separated from “wanting” [42, 43].
• Indeed, in the original Adverse Childhood Experiences (ACEs) study, Felitti et al. (1998) found that more ACEs increased the odds of subsequent drug and alcohol use.

An individual exposed to drug use at an early age can be influenced by social modeling (or learning via observation). Additionally, certain environments have specific social norms related to drug use (e.g., “Everyone experiments a little with drugs in college”). Genetics and biology are a part of the picture—albeit not the entire picture. Although there is no “addiction gene” to definitively identify a person as being at risk for addiction, it is evident through twin studies, adoption studies, family studies, and more recently, epigenetic studies that addiction has a genetic component.

What is the treatment for substance use disorder?

Given the way their lives are structured I think its very, very hard for them to stop. It has to do with dislocation, alientation, poverty and all these sort of factors and a lack of care by the larger society for people who are suffering. When you put all those https://detroitapartment.net/how-to-get-rid-of-dependence-on-social-networks.html factors on the table, then you don’t have to use the disease label to explain why some people can get really deeply stuck in addiction. Prevention efforts and treatment approaches for addiction are generally as successful as those for other chronic diseases.

Sometimes a potential addiction-related gene is discovered in people, like in the example above. Other genes are discovered first in an animal model and confirmed later in people. Like most other diseases, it’s genes and environment together that determine the risk.

Addiction

Other large societal factors include the health, economic, educational, and social policies that help to maintain economic or social inequalities between groups in society. Prevention strategies at this level include efforts to promote societal norms that protect against violence as well as efforts to strengthen household financial security, education and employment opportunities, and other policies that affect the structural determinants of health. Then if you do get into rehab, you’re putting yourself in somebody else’s hands and you’re going with the program. But the best way to combat addiction is through setting different goals for yourself and setting your own goals. “I want this for my life, I don’t want that, I want to change.” That kind of self-perspective change and self-development of future goals and orientation is critical. The parts of the brain that become activated when craving is triggered by cues changes.

There are many different perspectives from which to view the human mind and behavior and the biological perspective represents just one of these approaches. This perspective has grown considerably in recent years as the technology used to study the brain and nervous system has grown increasingly advanced. Natural selection, first described by Charles Darwin, influences whether certain behavior patterns are passed down to future generations. Behaviors that aid in survival are more likely to be passed down while those that prove dangerous are less likely to be inherited. If you’re being told what to do, you fall into a position of helplessness or disempowerment, which makes it hard to develop this head of steam, this effortful strength and self-control and willpower.
