Substance use and its effects
Loice Vavi Health Matters
Definition
Drug addiction, also called substance use disorder, is a dependence on a legal or illegal drug or medication. Keep in mind that alcohol and nicotine are legal substances, but are also considered drugs.
When you’re addicted, you’re not able to control your drug use and you may continue using the drug despite the harm it causes. Drug addiction can cause an intense craving for the drug. You may want to quit, but most people find they can’t do it on their own.
Drug addiction can cause serious, long-term consequences, including problems with physical and mental health, relationships, employment, and the law.
Symptoms
Most drug addictions start with experimental use of a drug in social situations. For some people, the drug use becomes more frequent. The risk of addiction and how fast you become dependent varies by drug. Some drugs have a higher risk and cause dependency more quickly than others.
As time passes, you may need larger doses of the drug to get high. Soon you may need the drug just to feel good. As your drug use increases, you may find that it’s increasingly difficult to go without the drug. Attempts to stop drug use may cause intense cravings and make you feel physically ill (withdrawal symptoms).
Drug addiction symptoms or behaviours include, among others:
Feeling that you have to use the drug regularly — this can be daily or even several times a day
Having intense urges for the drug
Over time, needing more of the drug to get the same effect
Making certain that you maintain a supply of the drug
Spending money on the drug, even though you can’t afford it
Not meeting obligations and work responsibilities, or cutting back on social or recreational activities because of drug use
Doing things to get the drug that you normally wouldn’t do, such as stealing
Driving or doing other risky activities when you’re under the influence of the drug
Focusing more and more time and energy on getting and using the drug
Failing in your attempts to stop using the drug
Experiencing withdrawal symptoms when you attempt to stop taking the drug
Recognising drug abuse in family members
Sometimes it’s difficult to distinguish normal teenage moodiness or angst from signs of drug use. Possible indications that your teenager or other family member is using drugs include:
Problems at school or work — frequently missing school or work, a sudden disinterest in school activities or work, or a drop in grades or work performance
Physical health issues — lack of energy and motivation
Neglected appearance — lack of interest in clothing, grooming or looks
Changes in behaviour — exaggerated efforts to bar family members from entering his or her room or being secretive about where he or she goes with friends; or drastic changes in behaviour and in relationships with family and friends
Spending money — sudden requests for money without a reasonable explanation; or your discovery that money is missing or has been stolen or that items have disappeared from your home, indicating maybe they’re being sold to support drug use
