Chronic Care
Considerable
investment of money and effort has been directed toward drug abuse prevention
programs. Afer a decade of prevention efforts small
gains are becoming evident. Treatment programs on the otherhand have proved
to be effective in reducing drug abuse. Unfortunately, among dependent substance
abusers in all age categories, only about a quarter get treatment.2
Effectiveness of treatment programs range from forty to eighty percent. A program
is considered effective if it demonstrates a fifty percent reduction in substance
use after six months. Treatment has been shown to be less expensive than incarceration
and untreated addiction. Treatment, however, does not cure addiction, it seeks
to manage the disease as a chronic, relapsing disorder. 18
Addiction in teenagers may
be uncovered during a review of problems, such as lack of motivation and ability
to do school work, maintain an active social life, hold a job, or engage in
normal social activities. Nurses may encounter teenagers with addictions in
a clinic visit for either mental or physical problems. Depression, anxiety,
hostility and incoherence are commonly noted by parents of chronic juvenile
drug users. A weakening of the immune system leading to frequent viral and bacterial
infection is another common observation. Chronic cough and an aggravation of
asthma may be traced to smoking. Drug use may have led to the transmission of
HIV/AIDS or hepatitis B or C, either through injection or through high risk
sexual contact under the influence of drugs. Damaged blood vessels and skin
abscesses may have been incurred through self-injections. 19
Marijuana has been linked with lack of motivation in adolescents as well as
work-related inconsistency. The causal relationship is uncertain, however, and
reverses with discontinuation of use. Long-term effects of regular MDMA use,
with its potential for psychological addiction and tolerance, include exhaustion,
mood swings, dizziness, vertigo and possible brain damage. LSD users may exhibit
mental fragmentation along with the unpleasant occurrences of flashbacks weeks
or months later. Nurses need to be aware of these possibilities among adolescents
seeking healthcare, while also keeping themselves up-to-date on the prevalence
of amphetamine addiction and its devastation on health. These highly addictive
and quick tolerance-building substances are typically taken in a cycle of repeated
binges for four to five days at a time, followed by exhaustion, round-the-clock
sleeping and ravenous eating. Withdrawal symptoms of exhaustion, depression
and mental incoherence are severe. Addicts tend to be extremely violent. The
long-term effects of amphetamine use are: weight loss, malnutrition, fatal kidney
and lung disorders, permanent psychological problems, a weakened immune system
and liver damage. Brain damage from chronic use may lead to speech and cognitive
disability that includes psychotic features leading to homicidal or suicidal
thoughts. With meth abusers, acute lead poisoning is also possible.
In one study of the frequency that student nurses included an assessment of substance abuse in patients, it was found that only 55% of the students asked their patients about alcohol consumption and 20% asked about drug usage without being directed to do so. On prompting, 90% collected information on alcohol use and 80% collected information on drug use.20 This study points out the need for establishing substance abuse assessments as a routine part of collecting a health history. Nurses may need this information about the use of illicit drugs in a hospitalized adolescent experiencing withdrawal symptoms. Also, there may be contraindications regarding the use of such prescription drugs as MAOI inhibitors in a patient who has recently taken street drugs.
