People who experience problems with mental health conditions may also experience issues with substance use (alcohol and/or other drugs). Sometimes the person may be trying to escape how they feel. In other cases, the use of substances can lead to someone having issues with their mental health.

A person who is diagnosed with a substance use disorder uses a particular substance regularly. Over time, they may build up tolerance, meaning they need to take larger amounts of something in order to get the same effect. The person may spend a lot of time thinking about how they can get it and how they can get money to pay for it. They will probably find it difficult to stop taking the substance because long-term, regular use can lead to uncomfortable withdrawal effects.

Excessive use of alcohol and/or other drugs can also cause problems with personal care and physical health. It may put pressure on relationships and cause financial stress. It can also lead to changes in mood or behaviour, such as increased aggression or irritability, depression and lethargy.
