Week 3: Physiological Effects of Substances

Week 3: Physiological Effects of Substances

This is your brain. This is your brain on drugs.

—The Museum of Broadcast Communications

What does it take to convince someone of the negative short- and long-term effects of substances so they will quit abusing them? In 1987, the Advertising Media Partnership for a Drug-Free America (PDFA) created its largest advertising campaign ever with this slogan and an iconic image of an egg frying in a pan. The creative image took only seconds to convey the dangerous physical effects of drugs. The fragility of the brain captured by the egg sizzling in oil, and the image of frying—which has become part of the slang for getting “high”—made a lasting impression on the target audience for the PDFA campaign.

The reality is that the physiological effects of substance abuse are not always obvious from the “outside.” One cannot see a brain “frying” like an egg in a pan. Fortunately, certain hallmarks of addiction, including tolerance and withdrawal, have been established that indicate to some extent whether someone is becoming or is in danger of becoming addicted. This week, you analyze the relationship between the hallmarks of addiction and the physiological effects of substances. You also evaluate the dangers of physiological effects of addictive substances and develop a communication strategy to warn against them.

Discussion: Short- and Long-Term Dangers of Substances

Addiction may look different in different individuals. There are certain hallmarks of addiction, including tolerance and withdrawal, which have been established for recognizing when an individual crosses over from use, to abuse, to addiction. A distinct relationship exists between the hallmarks of addiction and the physiological effects of addictive substances.

In this Discussion, you will examine these hallmarks and the physiological effects of addictive substances as you provide an example that demonstrates their relationship.

To prepare for this Discussion:

  • Review Foundations of Addictions Counseling, Chapter 2, “Substance Addictions.”
  • Review the report, “Drugs, Brains, and Behavior: The Science of Addiction.”
  • Review the article “Neurobiology of Alcohol Dependence,”
  • Review the document titled, “Physiological Effects of Addictive Substances.”

By Day 4

Post your response to the following:

What is the relationship between hallmarks of addiction and physiological effects of addictive substances? Provide an example that best describes this relationship and explain why. Provide at least one citation to support your example.

Note: The confidentiality of the Discussion cannot be guaranteed. Therefore, please do not include identifying details of actual individuals or organizations in your responses.

Be specific and use the week’s Learning Resources in your response.

By Day 6

Respond to at least one colleague:

  • Offer another perspective based on your perspective on the hallmarks of addiction.
  • Confirm or expand on someone else’s post using specific examples or insights.

Assignment: Creating Awareness of Risks

Although many new nationally known programs are available aimed at preventing substance abuse and addictions, many people develop addictions every year. The tendency to develop addiction varies with different ages, cultures, and other factors. One population that is most at risk of developing addictions is the high-school-age population. Studies have shown that adolescents perceive themselves as invulnerable to poor health (Santrock, 2010). In addition, physical development is taking place that makes them more at risk for substance abuse. The amygdala, for example, which is more driven by primitive impulses, is in a state of transition. Young adults do not have fully developed prefrontal cortexes, which are responsible for delaying gratification, controlling impulses, planning, prioritizing, and focusing, until later adolescence (Perkinson, 2012). This week, you will develop a communication tool to create awareness of the short- and long-term physiological dangers of substance addiction for this important-to-reach high-school-age population.

To prepare for this Assignment:

  • Review the article “Drug Facts: High School and Youth Trends”.
  • Become familiar with some graphic tools that may aid you in preparation of your poster.

By Day 7

Submit a visually interesting poster for a high-school-age population that includes the following:

  • Short- and long-term physiological effects of an addictive substance
  • A slogan or paragraph that translates facts into a compelling message for this population

Be specific and draw on the required readings for this week in the creation of your poster.

Note: Create your poster in whichever program works best for you, such as Microsoft Word, Microsoft Publisher (to create a PDF), or any open-source program you choose. You may also submit a photograph of your poster as a digital file, such as a jpeg or tiff file.
