Psychoactive drugs are substances that affect the brain and alter thinking, perception, and memory. Legal drugs can also have psychoactive effects, but the term "psychoactive drugs" is typically used to refer to illegal drugs or prescription medications that are taken for non-medical purposes. Hallucinogens are a specific class of psychoactive drugs that can cause hallucinations and other altered perceptions.

Accepted Answer

Psychoactive drugs are drugs that have the ability to influence thinking, perception, and memory, which can result in altered states of consciousness, mood, and behavior. These drugs can include stimulants, depressants, hallucinogens, and opioids, among others, and can produce a wide range of effects on the brain and body.

Question 4

Which of the following statements is true concerning cocaine use in the United States?

Accepted Answer

Cocaine was indeed one of the original ingredients of Coca-Cola, which was first sold in the late 1800s. However, due to increasing public concern about the dangers of cocaine, the company removed the ingredient in 1903 and replaced it with caffeine and other stimulants. Choice A is false, as cocaine was not synthesized until the 1800s and was not widely used until later in the century. Choice C is also false, as while some historical figures may have used coca leaves (which contain trace amounts of cocaine), it is unlikely they used the processed drug in its modern form. Finally, choice D is incorrect, as heroin and cocaine are two separate drugs with different chemical compositions and effects on the body.

Question 5

The two most important symptoms of substance dependence are:

Accepted Answer

Tolerance and withdrawal are the two most important symptoms of substance dependence. Tolerance means that the person needs increasing amounts of the substance to achieve the desired effects, while withdrawal refers to the unpleasant symptoms that occur when the person stops using the substance. These two symptoms are key indicators of an individual's dependence on the substance.

Question 6

Which of the following is classified as a depressant?

Accepted Answer

Alcohol is classified as a depressant because it slows down the central nervous system, which can cause decreased heart rate, lowered blood pressure, and impaired cognitive and physical function. Cocaine and heroin are both classified as stimulants, while marijuana is considered a psychoactive drug with both stimulant and depressant effects.

Question 7

The need to take a drug in order to avoid withdrawal symptoms is called _________.

Accepted Answer

Physical dependence is the need to take a drug in order to avoid withdrawal symptoms. A craving is a strong desire or urge to use drugs, but it does not necessarily involve withdrawal symptoms. Tolerance is a condition where the body requires larger doses of a drug over time to achieve the same effect, and it is not directly related to withdrawal symptoms. Obsessive compulsion is a behavior that involves recurrent, unwanted thoughts or impulses that typically result in repetitive actions. While it may be a factor in drug use disorders, it is not directly related to physical dependence or withdrawal symptoms.

Question 8

A person will often take a barbiturate as a ________.

Accepted Answer

Barbiturates are commonly used as a sleep aid due to their sedative effects on the central nervous system. They can help induce sleep and promote relaxation. However, they can also be highly addictive and lead to dangerous health consequences if misused.

Question 9

Nicotine is a ______________.

Accepted Answer

Nicotine is a stimulant drug that affects the central nervous system and increases activity in the brain. It also increases heart rate, blood pressure, and respiration.

Question 10

Selma notices that as her supply of marijuana decreases she starts thinking more and more about where she can get another supply as well as feeling nervous and anxious.This is an example of ____________.

Accepted Answer

The fact that Selma is feeling nervous and anxious about running out of marijuana indicates that there is a psychological dependence at play. She has become reliant on the substance to alleviate her anxiety and not having access to it is causing distress. This is not necessarily an indication of withdrawal or tolerance, which are both physical responses to substance use. While physiological dependence can also contribute to these symptoms, the emphasis on Selma's thoughts and feelings suggests that psychological dependence is the primary factor in play.

Question 11

Which of the following indicators reflects the possibility of physical dependence?

Accepted Answer

Drug tolerance is a physiological adaptation to a drug that reduces the drug's effect over time. Tolerance is a clear indicator of physical dependence, which means a person's body has adapted to the drug and withdrawal symptoms will occur if the drug is stopped abruptly. Obsessing about drugs and abusing drugs can also be signs of addiction, but they do not necessarily indicate physical dependence. Getting caught with a drug is a legal consequence and does not necessarily reflect physical dependence.

Question 12

Caffeine is a _______________.

Accepted Answer

Caffeine is classified as a stimulant because it can increase alertness, energy, and cognitive function.

Question 13

Accepted Answer

Accepted Answer

Benzedrine, methedrine, and dexedrine are all examples of amphetamines, which are stimulants that affect the central nervous system. They are often used to treat conditions such as ADHD and narcolepsy, but can also be abused for their euphoric and energizing effects. They are not narcotics, depressants, or illegal when used for legitimate medical purposes.

Question 17

Russell needs more of the drug he has been using to get the normal high he got when he first started.Russell is experiencing _______________.

Accepted Answer

Drug tolerance occurs when a person's body becomes used to the effects of a drug and requires higher doses to achieve the same high or effect. This matches the scenario presented in the question where Russell needs more of the drug to get the normal high he got when he first started. Withdrawal and detoxification are different stages of the recovery process when someone stops using a drug, and overwithdrawal is not a recognized term.

Question 18

After taking a drug for several years,Bruce decides to quit taking the drug.He begins to experience a variety of physical symptoms,psychological symptoms such as irritability,and a strong craving for the substance.What term is used to describe what Bruce is experiencing?

Accepted Answer

Bruce is experiencing withdrawal, which is a set of physical and psychological symptoms that occur when a person stops taking a drug they have been using for a prolonged period. This is different from tolerance, which is a reduction in the effectiveness of a drug that occurs with repeated use, and drug intoxication, which is the state of being mentally and physically impaired as a result of taking a drug. Physical dependence is a condition in which a person's body has adapted to the presence of a drug and requires it to function normally, and withdrawal is a symptom of physical dependence.

Question 19

Drugs that speed up the functioning of the nervous system are called _____________.

Accepted Answer

Stimulants are drugs that increase the activity of the nervous system, including increased heart rate, increased blood pressure, and increased alertness. Examples of stimulants include caffeine, amphetamines, and cocaine. Depressants, on the other hand, slow down the functioning of the nervous system, and include drugs like alcohol, benzodiazepines, and barbiturates. Narcotics are a class of drugs that produce analgesic (pain-killing) effects, and include drugs like morphine, codeine, and heroin. Psychogenics are a broad category of drugs that affect the mind, including hallucinogens, deliriants, and dissociatives.
