Substance abuse begins when someone takes a substance to change the way they feel currently. Everyone knows what kind of damage illegal substances like
heroin, crack cocaine and methamphetamine can do, but prescription drugs can also be abused when people use them for non-medical reasons or outside of the amount they are prescribed.
Although drug addiction and drug abuse are closely linked, there is a difference between the two conditions. For instance, if someone doesn’t only abuses drugs three or four times a year, they may show signs of drug abuse but not addiction. However, if someone regularly abuses a substance and makes their entire life about using and obtaining the substance, that person shows signs of addiction.
Even when a prescription drug is prescribed for a medical reason, sometimes patients can become chemically dependent on the drug – especially opiates or benzodiazepines. While there is a difference between a drug dependence and a drug addiction, these two conditions often go together as well.
