Question 2

Recent evidence suggests that opiates kill pain because they ____.

Accepted Answer

Opiates are similar in structure to the body's natural painkillers, such as endorphins, and can occupy the receptor sites in the brain that are designed to receive these natural painkillers. By occupying these receptor sites, opiates can effectively diminish the sensation of pain.

Question 4

Kevin takes a highly addictive drug that activates the brain's painkilling and mood-altering systems. Kevin is least likely to be taking ____.

Accepted Answer

Cocaine primarily affects the brain's reward and pleasure systems, not the painkilling and mood-altering systems that are affected by opioids such as morphine, heroin, and opium.

Question 5

How do opiates compare with CNS-stimulating and CNS-depressant drugs?

Accepted Answer

Opiates are CNS-depressant drugs, meaning they slow down activity in the central nervous system. In contrast, CNS-stimulating drugs increase activity in the central nervous system. Opiates do not cause hallucinations or dreamlike fantasies like some CNS-stimulating drugs do. Additionally, physical dependence on opiates is a well-known phenomenon. The legal status of different drugs is unrelated to their effects on the CNS.

Question 6

Matthew has just taken a drug that acts very similarly to the body's own endorphins. This drug is most likely to be ____.

Accepted Answer

Endorphins are naturally occurring chemicals in the body that act as painkillers and mood-enhancers. Opium is a drug that mimics the effects of these chemicals, making it the most likely answer. Alcohol, LSD, and marijuana have different modes of action and do not directly mimic endorphins.

Question 7

Seeta takes a drug that reduces her drowsiness and enhances her mood. However, at high doses, she experiences anxiety and tremors. After prolonged use, Seeta can build up a tolerance and physical dependence to the drug. Seetahas most likely ingested ____.

Accepted Answer

Caffeine is known to reduce drowsiness, enhance mood, and at high doses, can cause anxiety and tremors. Prolonged use can lead to tolerance and physical dependence, matching the description given.

Question 8

Paul uses ____to make him feel more confident and optimistic. It also reduces pain and can cause death. This drug is a(n)____.

Accepted Answer

The drug being described is cocaine, which is a CNS (central nervous system) stimulating drug. It can cause feelings of confidence and optimism, as well as reduce pain, but can also be deadly in high doses. None of the other choices fit the description.

Question 9

Louise uses a drug that causes her to relax and go to sleep. Her attention is lowered, and she experiences mild euphoria along with decreased muscle coordination. Louise is using ____.

Accepted Answer

The symptoms described are consistent with the effects of barbiturates, which are depressant drugs that reduce nervous system activity and can produce relaxation, sedation, euphoria, and impaired coordination. Cocaine and LSD are stimulant drugs that increase nervous system activity and would not produce similar symptoms. While marijuana is also a depressant drug, it typically produces more mild effects such as relaxation and altered perception, and would not necessarily cause significant decreases in muscle coordination.

Question 10

Long-term users of barbiturates, such as sleeping pills, are least likely to experience which symptom?

Accepted Answer

Barbiturates, commonly used as sedatives or sleeping pills, do not typically cause extreme weight gain. Instead, they are more associated with symptoms such as violent outbursts, seizures, and hallucinations, especially with long-term use or during withdrawal.

Question 11

Ginnie ingests a particular drug and experiences a loss of contact with reality and distorted sensory input. This drug is most likely ____.

Accepted Answer

The symptoms described are characteristic of hallucinogenic drugs, which can cause altered perceptions and disconnect from reality. Amphetamines, barbiturates, and opiates have different effects and symptoms.

Question 12

Alcohol and heroin are similar in that both ____.

Accepted Answer

Both alcohol and heroin slow down mental and physical activity.

Question 13

Betty was initially taking a psychoactive drug to help her lose weight and stay awake in class. Unfortunately, she has begun to experience restlessness and sleeplessness. Betty is experiencing the effects of prolonged use of ____.

Accepted Answer

The symptoms that Betty is experiencing, restlessness and sleeplessness, are common side effects of amphetamines, which are psychoactive drugs commonly used to suppress appetite and increase alertness. Caffeine can have similar effects, but it is not typically used as a weight loss aid in the same way that amphetamines are. Cocaine is a highly addictive stimulant drug with similar effects to amphetamines but is not prescribed for weight loss. Opium is a narcotic and has a different set of effects.

Question 14

Brodie ingests a drug and experiences a distortion of time and sensory input. He is at risk for experiencing severe short-term memory loss and violent outbursts. The drug he has taken is most likely ____.

Accepted Answer

The drug that causes time and sensory distortion, short-term memory loss, and violent outbursts is LSD. Caffeine is a mild stimulant and does not have these effects. Barbiturates and opium are depressants and also do not typically cause these symptoms.

Question 15

Tricia likes to take drugs that will increase her behavioral and mental activity. Tricia is least likely to use ____.

Accepted Answer

Barbiturates are depressants and are not likely to increase behavioral and mental activity. The other options listed are stimulants and more likely to achieve Tricia's desired effects.

Question 16

After taking a pill, Dante feels euphoric. In fact, doesn't feel any pain when he rams his knee into the table. Dante most likely took a(n)____.

Accepted Answer

Opiates are painkillers that are known to produce feelings of euphoria and can also cause a numbing effect, which would explain why Dante did not feel any pain after hitting his knee. Tranquilizing drugs (A) would not necessarily produce euphoria and could actually cause Dante to feel more sedated. CNS stimulating drugs (B) would not have a painkilling effect and could actually make Dante more sensitive to pain. Hallucinogenic drugs (D) can cause alterations in perception and mood, but would not necessarily produce a painkilling effect.

Question 17

The risk of relapse for people who have given up addictive drugs is elevated because of ____, which means that for some people, exposure to addictive drugs changes gene expression.

Accepted Answer

Epigenetic effects refer to changes in gene expression that can be passed down from one generation to the next. Exposure to addictive drugs can lead to epigenetic changes that increase the risk of relapse, as the brain may become more sensitive to the effects of the drug. This can lead to an intensification of cravings and the possibility of returning to drug use.

Question 18

After taking a drug, Jerald has what he describes as an out-of-body experience. With repeated use, this drug could cause damage to memory-related structures, such as the hippocampus. Jerald is likely taking____, which is a(n)____ drug.

Accepted Answer

Ketamine is a dissociative drug that can cause users to feel as though they are having an out-of-body experience. Chronic use of ketamine has been shown to cause damage to the hippocampus, which is involved in memory processing.

Question 19

Sameera occasionally uses LSD. Her friend Lisa occasionally uses morphine. Their friend Amy is a social drinker. Which individual is the least likely to become dependent on the drug she is using?

Accepted Answer

The answer of Sameera occasionally uses LSD. Her friend Lisa...

Question 20

Mitch takes a drug and feels that his behavior is more rapid and energetic, and notices that he can work more quickly aftertaking this drug. His friends observe that Mitch is also more anxious and worries that others are watching him when he is using the drug. Mitch is most likely taking ____.

Accepted Answer

The symptoms described (increased energy, increased productivity, anxiety) are consistent with the effects of amphetamines, which stimulate the central nervous system. LSD and marijuana can have different effects, such as hallucinations and altered perception. Librium is a benzodiazepine, which is a sedative that would not produce the described effects.
