• It is the tendency to preserve of a constant internal state and
it occurs in all organisms. Homeostasis motivates us
sometimes without us understanding it. (e.g.Addison’s ….
Develop preference to eat salty )
• Addiction and homeostasis (Tolerance and withdrawal).
• Set point of hunger, thirt… hypothalamus
• Complex drives…. Hypothalamus, signals from other body
parts, cultural factors (eating.. Anorexia nervosa)
•Most abused substances can be classified as
stimulants, sedatives, opioids, or
hallucinogens, and related agents.
•Substance abuse is a pattern of
abnormal substance use that leads to
impairment of occupational, physical, or
social functioning.
•Substance dependence is substance
abuse plus withdrawal symptoms,
tolerance, or a pattern of repetitive use.
•Withdrawal is the development of physical or
psychological symptoms after the reduction or
cessation of intake of a substance.
•Tolerance is the need for increased amounts of
the substance to achieve the same positive
psychological effect.
•Cross-tolerance is the development of
tolerance to one substance as the result of
using another substance.
•Epidemiology differs from a country to another
but usually it is more common among young
adult males.
•Any substance abuse life time prevalence
according to the IMHS is 0.9% (1.5% in males,
and 0.25 in females) in Iraq. More common in
young than older, urban than rural (1).
• In study 2014 all over Iraq lifetime prevalence of drug use:
Tobacco: (29.0%); Alcohol, (8.6%); Licit drug misuse (2.5%,)
and Illicit drug use (0.4%) (2) . This study also found that:
• Anabolic steroids are the most widely used licit drug in Iraq
followed by bnz & benzhexol. In the North of Iraq, there are
concerns of increasing misuse of tramadol.
• Cannabis is the most widely used illicit drug, but use of
stimulants (Amphitamines and Captagon) in the South of
Iraq is present. This finding is consistent with worldwide
data, but in Iraq, this gender difference is either particularly
great.
• Lifetime rates of licit and illicit drug use were higher among
younger participants (18-34 years), those with less education
(less than primary school) and those who were not working.
