Some substances are used as medicine, like prescription and over-the-counter drugs. Other examples of substances are coffee, cigarettes, alcohol, cannabis, and illegal drugs.
The term ‘substance use’ refers to the use of drugs or alcohol. There are varied levels of risk that come with using any substance.
Why do people use substances?
There are many different reasons; someone may use alcohol to wind down at the end of a busy week. Or someone who has been injured may use opioid medication to manage their pain.
Not all substance use is harmful – some people who use substances do not experience challenges. If alcohol or other drugs is causing harm to you or others, it could be a sign of a substance use challenge.
It’s possible to experience mental health and substance use challenges at the same time. For example, someone dealing with stress, anxiety, depression or another mental health challenge may use alcohol or other drugs to cope with how they’re feeling. This is called a concurrent disorder.
The signs of a substance use challenge depend on the type you use and how that substance affects you. Substance use challenges can include the use of alcohol and other drugs. And substances affect people in different ways.
There are some signs that you may be experiencing a substance use challenge. Alcohol or other drug use may begin to affect your daily life and activities. You may physically or emotionally need substances to get you through your day. Some other signs to watch for are:
With alcohol, you have blackouts; need to drink more to get the same effect; notice changes in your personality. You may deny that you are having a challenge.
With other drugs, you need more of the drug to feel “high” and take more of a drug over longer durations of time; you spend a lot of time trying to get the drug; you notice changes in your behaviour; you are moody or have problems sleeping.
Sometimes people are not aware they have become dependent on a substance until they experience withdrawal symptoms when they try to stop using alcohol or other drugs.
