Psychoactive Substance Abuse
Continuing to use substance even though
the person knows there are reoccurring
physical or psychological problems
being caused by using the substance
Psychoactive Substance Dependence






Craving (strong desire or sense of compulsion
to take a drug)
Change of tolerance (needing increased
amounts to achieve the same effect)
Difficulties in controlling drug-taking behavior
(onset, termination, levels of use)
Progressive neglect of alternative pleasures or
interests because of drug use (increasing
time for drug)
Withdrawal symptoms
Persisting with drug use despite clear
evidence of harmful consequences
Alcohol Intoxication
Alteration in behavior depending on the
amount of used alcohol and individual
variation and tolerance
(impaired judgment, mood lability, disinhibition of aggressive
impulses, social dysfunction)
0,3g/l euphoric effect
0,5g/l cognitive deficits, motor coordination problem
2,5g/l significant confusion, decreased state of
consciousness
4g/l coma, death
Alcohol Withdrawal Syndrome
Uncomplicated








Disorientation
Fluctuating consciousness

Addicts at the Doctor´s

Abstining addicts

Valid anamnesis including information
about addiction in an.
Carefully asking for used medication

excluding vital indication (benzodiazepines,
tramadol etc.)


Active addicts


Come in intoxication or withdrawal syndrome
Often come even with inflammatory complications
Irritability, manipulative
Asking for psychoactive substances
