Substance Abuse reading Flashcards
define substance related and addictive disorders
one of a range of probems associated with the use and abuse of drugs (alcohol, cocaine, heroine or other substances people use to alter the way they think, feel and behave). they are hugely costly to humans in financial terms
impulse control disorder
a disorder in which a person acts as on irresistible but potentially harmful impulses
polysubstance abuse
the use of multiple mind-behaviour altering substances such as drugs
define substance
chemical compound ingested to alter mood and behaviour
define psychoactive substances
substances such as ecstacy, that alter mood or behaviour
-safe drugs = no, nicotine, caffeine. greater mortality than all illegal combined
substance use
the ingestion of psychoactive substances in moderate amounts that does not significantly interfere with social, educational or occupational functioning
intoxication
a phsyiological reaction, such as impaired judgement and motor ability as well as mood changes reacting from the ingestion of a psychoactive substance
substance abuse
a pattern of psychoactive substance use leading to significant distress or impairment in social and occupational roles and in hazardous situations
DSM5 defines by how significnat interferes with life and not by amounts ingested
study of drug use and job outcomes
repeated hard drug (barbituates, amphetamines etc) use predicted poor job outcomes after college (with everything else controlled for)
how should we define addiction
a maladaptive pattern of substance use characterised by the need for increased amounts to achieve the desired effect when the substance is withdrawn, unsuccesful efforts to control its use and substantial effort expended to seek it or recover from it = addiction
tolerance
the need for increased amounts of a substance to achieve the desired effect, and a diminished effect without continued use of the same amount
withdrawal
a severly negative physiological reaction to removal of a psychoactive substance which can be alleviated by the same or similar substance
eg headache in the morning without caffeine
alcohol = delerium, hallucinations, body tremours
cocaine = anxiety, lack of motivation, boredom
LSD = severe physical
cannabis = nervousness, appetite change, sleep disturbance
drug seeking behaviours
measure of dependence
eg stealing, even standing outside in the cold, alone to smoke
how DSM5 describes substance abuse and addiction
4 = abuse and dependence were different 5 = combined and described in terms of levels of severity mild = 2 or 3 /11 symptoms moderate = 4 or 5 /11 symptoms severe = 6 or more /11 symptoms
why is use of substances dangerous full stop
we can use them and not abuse them but we do not know ahead of time who might lose control and abuse / dependence
can there be dependence but no abuse
yes
cancer patient dependent on morphine but not abusing it as manages their pain
diagnostic issues with sud
used to be part of other problems = sociopathic personality disturbances
sign of moral weakness
genetics and bio vulnerability was hardly acknowledged
researchers estimate 3/4 of those in treatment = an additional dis (mood, anxiety, PTSD)
=6 week rule
explain the six week rule
if symptoms appear during intoxication or within 6 weeks after withdrawal from drugs = not considered a separate disorder
how do we group drugs
6 categories depressant stimulants opiates hallucinogens other drugs gambling
depressants
psychoactive substance that results in behavioural sedation eg alcohol, sedatives, hypnotic and anxiolytic drugs
stimulants
psychoactive substance that elevates mood, activity and altertness eg amphetamines, caffeine, cocaine and nicotine
opiates
addictive psychoactive substance (heroine, opium, morphine) that causes temporary euphoria and analgesia
hallucinogens
any psychoactive substance (LSD, mrijuana) that can produce delusions, hallucinations, paranoia and altered sensory perception
other drugs of abuse
other substances that are abused but do not fit neatly into one of the major drug categories (inhalants, steroids)
