Tobacco

23
Q

Amphetamines

A
  • DSM-5 diagnostic criteria for intoxication in amphetamine use
    disorders include
  • Behavioural symptoms: euphoria or affective blunting, anxiety etc.
  • Physiological symptoms: changes in HR, BP, chills etc.
  • Stimulate central nervous system
  • Enhance activity of norepinephrine and dopamine
  • Lead to hallucinations and delusions
24
Q

Cocaine

A
  • Derived from leaves of the coca plant
  • Increases alertness, euphoria, increases BP and pulse
  • High from dopamine system impact
  • Snorted, smoked or injected (crack cocaine)
25
cocaine clinical description
increases alertness, blood pressure; causes insomnia
26
Caffeine related disorders
* “Gentle stimulant” found in tea, coffee, many soda drinks, cocoa products * Elevates mood, decreases fatigue * Causes insomnia * Tolerance and dependence with overuse * DSM-5 includes caffeine use disorder: * Problematic caffeine use that causes significant impairment and distress
27
Opioids
* Opiate: natural chemicals in opium poppy having a narcotic effect * Sleep-inducing, pain-relieving (analgesic) * Canada in grip of opioid crisis: prescription and illegal; high in First Nations adults * Withdrawal is unpleasant * Intravenously taken: risks of HIV
28
LSD
* LSD (acid; d-lysergic acid diethylamide) * “Acid” * Historically used as part of therapy * Other drugs * Psilocybin (mushrooms), lysergic acid amide, dimethyltryptamine (DMT), mescaline (peyote), phencyclidine (PCP) * Tolerance develops quickly * Limited withdrawal symptoms
29
LSD DSM criteria
* Perceptual changes: subjective intensification of perceptions, depersonalization, and hallucinations * Physical symptoms: pupillary dilation, rapid heartbeat, sweating, blurred vision (American Psychiatric Association, 2013). * “Bad trips” High Risk/ concerns with psychotic reactions

31
causes of substance use
Familial and Genetic Influences * Genetic vulnerability to drug abuse, alcoholism * A gene of chromosome 4 may prevent alcohol dependence * Alcohol dehydrogenase (ADH) may be absent in some people * Gene DRD2 may be related to alcoholism Neurobiological Influences * Psychoactive drugs activate reward centre of the brain * Sensitization: repeated exposure to stimulant drugs leads to increased dopamine release when taking the drug
32
Causes: psychological dimensions of substance use
Positive Reinforcement * Psychoactive drugs provide a pleasurable experience * Use increase leads to tolerance increase * Sometimes drugs are combined to enhance pleasurable experience Negative Reinforcement * Psychoactive drugs provide escape from physical pain (opioids), from stress (alcohol), or from panic and anxiety (benzodiazepines) * Opponent-process theory * Experience an unpleasant crash after being high
33
Treatment of substance use
