Combining alcohol and Adderall is dangerous and strongly discouraged due to their conflicting effects on the body. Adderall is a prescription stimulant containing amphetamine and dextroamphetamine, used to treat ADHD and narcolepsy by increasing alertness and focus. Alcohol, on the other hand, is a depressant that slows brain function and coordination. When taken together, alcohol can mask Adderall’s stimulating effects, leading users to drink more without realizing how intoxicated they are.
