The phrase "alcohol or drugs" refers to substances that are consumed for their mind-altering effects. Alcohol is a legal drug that can cause intoxication, relaxation and other changes in behavior when consumed in excess. Drugs refer to any chemical substance taken for non-medical purposes, including prescription drugs taken without a prescription or recreational drugs like marijuana, cocaine, LSD, etc. Both alcohol and drugs can have serious negative consequences if used irresponsibly, such as addiction, accidents, injuries, legal problems, and damage to relationships.
