Substance Misuse for Adults

Your Health

Understanding the Impact of Drugs

A drug is any substance that changes the way our mind and/or body works. It can affect the way we think, feel and act. In 2014, the cost of substance use in Canada – health care, lost productivity, criminal justice, and other direct costs – was $38.4 billion – or about $1,100 spent for every Canadian regardless of age. Almost 70% of the total costs were due to alcohol and tobacco.

Smoking, Alcohol and Other Drugs

Smoking causes about 45,000 deaths every year in Canada – nearly 1 in 5 deaths in Canada (2012) were attributable to smoking.

Alcohol is the most common drug used by Canadians – about 4 in every 5 Canadians reports consuming alcohol. In 2015, alcohol was responsible for about 77,000 hospitalizations in Canada – slightly more than the number of hospitalizations from heart attacks.

People use alcohol and other drugs for many reasons:

• To ‘fit in’ or because of peer pressure
• To cope with stress, emotions and other problems
• Because they feel exciting or risky
• To help relax or find pleasure

Youth are the most vulnerable to substance misuse because parts of the brain that control judgment and decision-making do not fully develop until their mid-20s.

Alcohol and tobacco are usually the first drugs that young people experiment with or use. Not all young people who try a substance will go on to have drug-related problems, but these substances create situations or environments that support continued drug use.4 Early use of drugs increases the risk of health consequences including addiction. Early prevention of alcohol and other drugs can go a long way to reduce the risks.
