DRUG ADDICTION IS A COMPLEX ILLNESS
There’s a Big Contribution to Big Biological / Genetic Contribution to Drug Abuse and Addiction… Drug Abuse and Addiction… ….Overlapping with Influences that Help Make Addiction a Complex Disease. ….Overlapping with Environmental Influences that Help Make Addiction a Complex Disease.
Environmental factors Drug related Individual related Society – community related
Drug related factors Availability –Legal and policy environment –Socio-cultural norms and attitudes Abuse liability –Reward or reinforcement –Non-toxic –route, duration of action
-44- Drugs: The vicious cycle Presence makes you feel good… (euphoria) Absence makes you feel miserable… (withdrawal)
-45- Taking drugs… NOT Taking drugs…..makes you feel good… (euphoria) likely that you will continue....makes you feel miserable… (withdrawal)..to avoid which you will continue.. Drugs: The vicious cycle
Individual related factors Self-medication theory –Co-morbid mental illnesses very common –Co-morbid symptoms even commoner Personality factors –‘novelty seeking’
Society related factors Family influence Peer influence Cultural and religious sanction & proscription Legal & policy environment The setting
-48- Part 3: Concept of Abuse
-49- Terminology Use Misuse / harmful use Abuse Dependence Addiction - older term, still used
-50- Terminology Use The ingestion of alcohol or other drugs without the experience of any negative consequences. If a student had drank a beer at a party and his parents had not found out we could say he had USED alcohol.
-51- Terminology Misuse When a person experiences negative consequence from the use of alcohol or other drugs it is clearly misuse. A 40-year old man uses alcohol occasionally, his boss throws a party and the man drinks more than usual and on the way home he is arrested by police.
-52- Terminology Abuse / harmful use Maladaptive pattern of use resulting in physical, social, legal harm Continued use in spite of negative consequences The same 40-year old man continues drinking alcohol after the incident.
-53- Terminology Dependence Drug taken in larger amounts or over longer period Persistent desire or unsuccessful efforts to cut down A great deal of time is spent in: obtaining the drug using the drug recovering from its effects Important social, occupational, or recreational activities given up or reduced Continued use despite harm Tolerance Withdrawal Addiction - older term, still used
Withdrawal symptoms Usually opposite of acute effects –Depressants: withdrawal-excitation –Stimulants: withdrawal-lethargy/’crash’
-56- Alcohol withdrawal: severe Severe Alcohol Withdrawal: “Delirium Tremens” All features of mild withdrawal Disorientation (unawareness of self and surroundings – time, place and person) Hallucinations Seizures (fits – ‘rum fits’) Can be fatal
-57- Opioid withdrawal Very distressing, but never fatal ! Opening of all holes ! Watering from eyes, nose Vomiting Loose motions Bodyache / pain Anxiety, restlessness, insomnia Premature ejaculation
-58- Cannabis withdrawal Non specific General discomfort Intense craving Anxiety, restlessness
-59- The usual drug-use ‘career’ Experimentation Depends upon Availability Peer pressure Socio-cultural norms Psychological factors
-60- Experimentation Occasional / Irregular use Depends upon Initial experiences Peer pressure The usual drug-use ‘career’
-61- Experimentation Occasional / Irregular use Regular use May be ‘Abuse’ or ‘Misuse’ Symptoms of harm start appearing The usual drug-use ‘career’
-62- Experimentation Occasional / Irregular use Regular use Dependence / Addiction The usual drug-use ‘career’
-63- Alcohol / Tobacco Charas / GanjaHeroin / SmackInjection Tidigesic From ‘softer’ to ‘harder’ drugs…
