ADDICTION
Addiction to alcohol is alcoholism ,alcoholics are found in all sections of
society. Alcohol causes intoxication and thus , act as a poision. The
drinkers begins with small doses, but many of them soon start
consuming large doses and become addicts.By the time they realise
that drinking is adversely affecting them , it is too late to give up.

• social pressure
•Desire for excitement
•Feeling of independence
•Liking of taste
•Desire to escape from harse reality of life like dissapointment and
failures
•The desire to offset the hardships & monotomy of life

14. WHAT HAPPENS WHEN ALCOHOL IS CONSUMED?
 Alcohol is quickly absorbed in stomach and upper part
of small intestine and reaches all tissues in minutes. Its
oxidation starts at once and a large amount of heat is
produced. Since heat is not needed in the body, it is
carried out by blood to the skin for dissipation. Since
the receptors of heat are located in the skin, the rush
of blood to the skin provides a false impression of
warmth to the body. The blood supply in all internal
organs is greatly reduced resulting in fall of
temperature in them . the energy released by alcohol
is not used in the life processes, rather the energy
consumed by having food is used upto get rid of the
extra heat.

15. Like many mental health disorders , several factors
may contribute to development of drug addiction
. The main factors are :
ENVIRONMENT: Environment factors ,including your
family’s beliefs and attitudes and exposure to a
peer group that encourages drug use ,seem to
play a role in initial drug use.
GENETIC: Once you’ve started using a drug, the
development into addiction may be influenced by
inherited(genetic) traits, which may delay or
speed up the disease progression.

17. RISK FACTORS :
 Family history of addiction
 Mental health disorder
