Free D403 Understanding Substance Abuse and Addiction Questions
1. John Belushi, Chris Farley, and River Phoenix are three famous people who overdosed while speed balling. Why is speed balling so dangerous that it can be lethal in overdose?
- The combination of cocaine and methcathinone causes such a rush of dopamine and norepinephrine that it causes tachycardia, high blood pressure and possible stroke.
- The combination of cocaine and heroin causes extreme aggression and feelings of invincibility so that people engage in dangerous, often lethal, activities.
- The combination of cocaine and heroin can mask the effects of each other so that the person doesn't realize how intoxicated they are, and increased use depresses their respiratory system, causing death.
- The combination of cocaine, LSD and ecstasy, all of which affect serotonin, can cause serotonin syndrome, which can cause death.
- The combination of cocaine, heroin, and tobacco (nicotine) creates energy and euphoria, along with excessive focus and attention, to the point where people can only attend to one activity, increasing the chance of accidental death (e.g., driving accidents) due to inability to attend to other conditions in their environment.
Explanation
Speedballing refers to the dangerous practice of combining cocaine (a stimulant) with heroin (a depressant). Cocaine stimulates the central nervous system, increasing heart rate and alertness, while heroin suppresses it, slowing breathing and inducing relaxation. Because these drugs have opposite effects, users may not fully perceive how intoxicated they are, leading them to take more of either substance. As cocaine’s effects wear off faster than heroin’s, the depressant action of heroin can cause respiratory failure, which is the primary cause of death in speedball overdoses.
2. What characterizes the initial stage of addiction, particularly in terms of usage frequency and motivations?
- Frequent use driven by physical dependence and withdrawal symptoms
- Infrequent use motivated by curiosity, social acceptance, and thrill-seeking
- Regular use resulting in significant changes in behavior and health
- Consistent use leading to severe psychological and physical health issues
Explanation
The initial stage of addiction is often marked by occasional or experimental use, where individuals engage in substance use primarily due to curiosity, peer influence, or the desire for excitement. At this point, physical dependence has not yet developed, and the user typically believes they have full control over their consumption. However, this stage lays the groundwork for later stages as tolerance and psychological dependence may begin to form if usage continues.
3. What is the primary function of the Reticular Activating System (RAS) in the brain?
- To regulate emotional responses
- To maintain consciousness and alertness
- To process sensory information
- To control motor functions
Explanation
The Reticular Activating System (RAS) is a critical network of neurons located in the brainstem responsible for maintaining consciousness, alertness, and the sleep-wake cycle. It acts as a sensory filter that determines which sensory information reaches conscious awareness, thereby regulating attention and arousal levels. When the RAS is active, a person remains alert and focused; when its activity decreases, it facilitates sleep and relaxation. Damage or dysfunction in the RAS can result in fatigue, drowsiness, or even coma, underscoring its essential role in maintaining wakefulness and responsiveness.
4. Which of the following best describes the primary function of the limbic system in the human brain?
- Regulating motor functions
- Processing sensory information
- Controlling emotions and drives
- Facilitating language comprehension
Explanation
The limbic system is a group of interconnected structures within the brain that primarily controls emotions, motivation, and drives, such as hunger, fear, pleasure, and sexual behavior. It also plays an essential role in the formation of memories. Key components of the limbic system include the amygdala, hippocampus, and hypothalamus. These structures work together to integrate emotional states with cognitive functions, influencing behavior and decision-making. Because of its central role in emotional regulation and memory, the limbic system is often referred to as the emotional center of the brain.
5. Both alcohol and barbiturate withdrawal
- usually last several months.
- are purely psychological.
- are far less serious than opiate withdrawal.
- can be minimized by administering another drug.
Explanation
Withdrawal from alcohol and barbiturates can be life-threatening due to their depressant effects on the central nervous system. Abrupt cessation can cause seizures, delirium tremens, and severe autonomic instability. To manage these symptoms and reduce risks, clinicians often administer cross-tolerant depressant drugs such as benzodiazepines, which help stabilize the patient and gradually taper the withdrawal process safely.
6. Meperidine or fentanyl are considered what type of analogue class
- Phenanthrenes
- Phenylpiperdine
- Diphenylheptanes
Explanation
Meperidine and fentanyl belong to the phenylpiperidine class of opioid analgesics. This class is characterized by a chemical structure that includes a piperidine ring, which differentiates it from other opioid classes such as the phenanthrenes (e.g., morphine, codeine) and diphenylheptanes (e.g., methadone). Drugs in the phenylpiperidine class are synthetic opioids known for their potent analgesic effects and rapid onset of action. Fentanyl, in particular, is many times stronger than morphine and is used in clinical settings for severe pain management and anesthesia.
7. Which of the following is an industrial or household solvent?
- Paint thinner
- Airplane glue
- Correction fluid
- All of the above
Explanation
Inhalants such as paint thinner, airplane glue, and correction fluid are all examples of industrial or household solvents commonly misused for their psychoactive effects. These substances produce vapors that, when inhaled, can cause euphoria, dizziness, and hallucinations. Because they are inexpensive and widely available, they are frequently abused—especially among adolescents. However, inhaling these solvents can lead to serious health effects, including brain and organ damage, and even sudden death.
8. Match the part of the brain to function: Cerebellum
- Emotion and memory
- Vital function
- Coordinated movement
- Hunger and Thirst; emotion
Explanation
The cerebellum, located at the back of the brain, plays a crucial role in coordinating voluntary movements, maintaining balance, posture, and motor learning. It ensures smooth, precise, and coordinated muscle activity. It does not control emotions, memory, or vital functions, which are regulated by other brain regions such as the limbic system and brainstem.
9. What is a significant risk associated with the use of Propoxyphene (Darvon) when combined with alcohol?
- It can lead to increased pain relief effectiveness.
- It may cause severe respiratory depression.
- It has no known interactions with alcohol.
- It enhances the euphoric effects of the drug.
Explanation
Combining Propoxyphene (Darvon), a narcotic pain reliever, with alcohol is extremely dangerous because both substances depress the central nervous system. This interaction can result in severe respiratory depression, where breathing becomes dangerously slow or may even stop altogether. The combined sedative effects also increase the risk of extreme drowsiness, loss of consciousness, and fatal overdose. Due to these serious risks, Propoxyphene was withdrawn from the U.S. market in 2010, but its misuse continues to pose a significant health threat when combined with alcohol or other depressants.
10. During the second stage of addiction, individuals often begin to use substances regularly. What are some common behavioral changes that may indicate this progression?
- Increased social interactions and improved relationships
- Regular use of substances alone, often to cope with stress or anxiety
- Complete cessation of substance use and improved mental clarity
- Engaging in new hobbies and activities unrelated to substance use
Explanation
In the second stage of addiction, known as regular use, individuals begin to incorporate substance use into their daily routines. They may use alone or turn to substances as a coping mechanism for stress, anxiety, or emotional pain. Behavioral signs include declining performance at work or school, withdrawal from family and friends, and neglect of responsibilities. This stage marks a critical transition from experimental or social use to psychological dependence, where the person begins to rely on the substance for emotional regulation.
