What are Schedule I substances?
Substances that have no accepted medical use in U.S. and have high abuse potential (e.g. heroin, LSD, marijuana, MDMA, etc.)
Physical dependency
Onset of withdrawal symptoms upon removal of drug (not all drugs produce)
Current scientific definition of addiction
A chronic relapsing disorder, characterized by compulsion to seek and take the drug, loss of control in limiting intake, and emergence of a negative emotional state when access to drug is prevented
Medical disease, not lack of willpower
DSM-5 on substance use disorder
maladaptive pattern of substance use for at least 12 months that has led to significant impairment or distress, by clinical standards
At least two of 11 additional criteria must be met
Severity component
Caffeine excluded because of mild withdrawal symptoms
What are the different levels of AUD, and how many components for each?
Mild AUD: 2-3 components
Moderate AUD: 4-5 components
Severe: 6+ components
Addiction phases
Non-problematic or recreational drug use -> escalation of drug use -> compulsive/problematic drug use -> Abstinence (withdrawal) -> relapse
Why are IV injection and inhalation/smoking the most addictive routes of administration?
- rapid drug entry into brain and fast onset of drug action (although short)
- strongest euphoric effects
Which routes of administration have the slowest speed of onset and the longest duration of action?
Oral and transdermal
Development of addiction
Goes from positive reinforcement (response produces positive outcome) to negative reinforcement (response removes aversive outcome during withdrawal)
Impulsive stage (reward, positive reinforcing effects) to compulsive stage (relief, negative reinforcing effects)
What factors can contribute to risk for addiction?
Heritability (.4-.6), environmental influences, gene x environment interactions
Psychosocial variables as well (e.g. minorities, younger age, inability to cope with stress, etc.)
Self-medication hypothesis
Stressful life events could trigger anxiety and mood disorders, which could lead to substance use in order to self-medicate
Shared etiology hypothesis
certain factors (genetic/environmental) contribute to elevated risk for both SUD and other disorders
Specific personality traits linked to SUD
Behavioral disinhibition, stress reduction, reward sensitivity (sensation seeking)
