Substance use disorders involve cognitive, behavioural and physiological symptoms caused by the misuse of substances such as alcohol, cannabis, opioids, hallucinogens, stimulants and sedatives. Many people like to drink alcohol or take recreational drugs, but this becomes a problem when it starts to interfere with everyday functioning.
Substance use disorders are often characterised by cravings for the substance as well as tolerance and withdrawal symptoms. Excessive use of substances can get in the way of work, school and home life, and can impact negatively on personal relationships. Seeking help from a psychologist can help to get you back on track.
