Substance abuse or misuse is formally defined as the continued misuse of any mind-altering substance that severely affects person's physical and mental health, social situation and responsibilities.
Alcohol dependence is the most common form of substance misuse, but any drug, including heroin, cocaine, crack and cannabis, comes into this category, as does the misuse of glue and aerosols.
Most forms of substance abuse may give you a temporary feeling of well-being or of being in control, but all of them can ultimately damage your health.
The most severe forms of substance misuse are normally treated by specialist drug and alcohol rehabilitation services.
