People with intellectual and developmental disabilities (IDD) can have substance use disorders (SUD). The risk of developing use disorders is significant. There is a lack of screening and formal testing for SUD in people with IDD.
People with IDD can often abuse alcohol, tobacco, and cannabis.
The risk of developing SUD is relatively high among IDD substance users. It is due to:
- Impulsivity (poor impulse control)
- Increased risk of trauma
- Possible lack of understanding about the reality for abuse
- What happens when you use drugs or alcohol (consequences of use)
Higher functioning people with IDD usually enjoy a greater level of independence. They are more likely to get access to drugs and alcohol. Also, they interact more with their community at large. They are apt to feel peer pressures and prejudice. They want to fit in with others.
