What is the primary effect of stimulants on the central and autonomic nervous systems?
They increase activity in these systems, resulting in euphoria, excitement, increased concentration, and reduced fatigue.
Which plant is cocaine derived from, and where is it primarily grown?
The coca plant, primarily grown in the South American Andes mountains.
What are some common side effects of high doses of stimulants?
Irritability, violent behavior, convulsions, and in rare cases, death.
List Seven examples of stimulants mentioned in Chapter 10.
Cocaine, amphetamines, nicotine, caffeine, khat, bath salts, betel.
What neurotransmitter does cocaine affect by inhibiting its reuptake?
Dopamine
What are the two main forms of cocaine, and how are they typically administered?
Powder cocaine (snorted, injected, or rubbed into gums) and crack cocaine (smoked).
What are some long-term effects of chronic cocaine use?
Memory loss, nasal tissue damage, lung damage, weight loss, renal failure, high blood pressure, and increased risk of stroke and aneurysm.
Why do powder cocaine and crack cocaine have different societal perceptions?
Societal perceptions differ due to demographic and socioeconomic differences in usage patterns, despite being chemically identical.
What neurotransmitters do amphetamines chemically resemble?
Norepinephrine and dopamine.
What were amphetamines originally used for during World War II?
To combat fatigue and maintain alertness in soldiers.
What are some withdrawal symptoms associated with amphetamine use?
Depression, disrupted REM sleep, fatigue, irritability, hunger, and violence.
Why is methamphetamine often referred to as the “poor man’s cocaine”?
It is cheap and can be made with locally available chemicals.
What is “meth mouth,” and what causes it?
Severe tooth decay caused by dry mouth, poor oral hygiene, and the acidic nature of methamphetamine
What populations are more likely to use crystal meth?
Street youth, gay and bisexual youth, and men who have sex with men.
What is the primary neurotransmitter released in large amounts when using methamphetamine?
Dopamine
What mental health condition is methylphenidate primarily used to treat?
ADHD (Attention-Deficit/Hyperactivity Disorder).
How does methylphenidate improve ADHD symptoms?
By preventing dopamine reuptake, increasing dopamine levels in the synaptic cleft and improving cognitive control.
What are some common side effects of methylphenidate use?
Loss of appetite, nervousness, cardiac arrhythmias, tics, and increased blood pressure.
Is there evidence that methylphenidate improves academic performance in people without ADHD?
No, studies show improved performance only in individuals with ADHD.
What are anorexiants prescribed for?
Short-term weight reduction and clinical obesity management.
What is Fen-Phen, and why was it discontinued?
A combination of fenfluramine and phentermine linked to cardiovascular problems.
How do decongestants like pseudoephedrine relieve nasal congestion?
By constricting blood vessels in the nasal passages.
Why was the availability of decongestants restricted after 2000?
Due to their potential use in methamphetamine production and associated health risks.
Where is khat traditionally used, and what are its primary effects?
Yemen and East Africa, where it reduces fatigue, suppresses hunger, and boosts concentration.
