20 Individual Related Factors Self-medication theory Co-morbid mental illnesses very common Co-morbid symptoms more common Personality factors ‘Novelty seeking’ 20

21 Society Related Factors Family influence Peer influence Cultural and religious sanction & proscription Legal & policy environment The setting 21

22 Terminology Use Misuse/harmful use Abuse Dependence Addiction – older term, still used 22

23 Use The ingestion of alcohol or other drugs without experiencing any negative consequences Example If a student had drunk a beer at a party and his parents had not found out we could say he had USED alcohol 23

24 Misuse When a person experiences negative consequences from the use of alcohol or other drugs it is clearly misuse Example 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 the police 24

25 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 25

26 Dependence A cluster of physiological, behavioural and cognitive phenomena in which use of a substance or class of substances takes on a much higher priority for an individual than other behaviours Three or more of the following criteria to be present for some time in a one-year period: Increasing tolerance Withdrawal Impaired control Preoccupation Continued use despite harm Craving 26

27 Tolerance Need for increasing the amount of substance consumed to achieve intoxication or the desired effect Markedly diminished effect with continued use of the same amount of substance Example A person ‘X’ started with one line of heroin smoking to get intoxicated; with time, he had to increase the dose to 1 pudiya per day to get the same amount of intoxication A person ‘Y’ started with 1 peg of whisky and got high; with continued use, has to now consume 3 pegs of whisky to get the same high 27

28 Withdrawal Set of symptoms experienced on stopping or reducing the amount of the substance after prolonged use Every class of substance (e.g. alcohol, opioids, etc.) has its own unique set of withdrawal symptoms 28

29 Early symptoms Anxiety Restlessness Yawning Nausea Sweating Runny nose Watery eyes Dilated pupils Abdominal cramps Early symptoms Anxiety Restlessness Yawning Nausea Sweating Runny nose Watery eyes Dilated pupils Abdominal cramps Delayed symptoms Restlessness Diarrhoea Vomiting Goose bumps Muscular spasm, pain Chills Increased heart rate, B.P. Increased temperature Delayed symptoms Restlessness Diarrhoea Vomiting Goose bumps Muscular spasm, pain Chills Increased heart rate, B.P. Increased temperature Opioid Withdrawal 29 Opening of all holes in the body!!

30 Impaired control of behaviour associated with substance use in terms of its starting the use of the substance, stopping the use of the substance, or controlling the level of use Example A person ‘X’ had thought that he would consume only 1 peg of alcohol on a given day, but he is not able to stop after 1 peg; continues to take more than 1 peg: loss of control A person ‘Y’ planned to stop his drug use, but is unable to do so: loss of control 30 Impaired Control

31 Preoccupation Preoccupation with the use of substance manifested as: Great amount of time spent in using the substance/procuring the substance/recovering from the effect of the substance Other activities which were pleasurable are given up as a result of the substance use Other interests/hobbies given up due to indulgence in substance use 31

32 Continuing use of the particular substance despite harmful consequences of the substance on the individual Strong desire to use the substance: Craving Craving can be spontaneous or in reaction to certain stimulus (e.g. place where the individual takes drugs, drug using friends, shop where the individual purchases drugs/alcohol, etc.). The craving in reaction to stimulus is called as ‘cue induced’ craving 32 Continued Use & Craving

33 Drug Dependence is : a chronic relapsing disorder a brain disorder, in which biological, psychological and social factors operate www.drugabuse.gov 33

34 Drugs and HIV risks Due to : Drug effects: Lowering of risk perception Mood changes- risk taking increases High risk behaviour – sharing of N/S Cognition impaired – may not remember to take precautions Motor functions – may not be able to take the precautions Mode of use : If injected: chances of sharing N/S and paraphernalia 34
