What might happen when alcohol is combined with another drug?

  1. The effects of the alcohol and the drug may both be increased. ✓
  2. Nothing will happen.
  3. The effects of the alcohol and the drug may both be reduced.
  4. The effects of only the alcohol may be reduced.

Answer: A. The effects of the alcohol and the drug may both be increased.

When alcohol is combined with another drug, the effects of both can be increased.

Why this is the answer

The handbook warns never to drink while taking other drugs. It says the combination can be dangerous and often makes the alcohol and the drug stronger. It gives the example that one drink with a cold remedy could affect you like several drinks. A separate passage says mixing alcohol and drugs severely cuts your driving ability. That evidence points to stronger effects from both, not no effect and not a reduction.

Why the other answers are wrong

Remember it

Remember: alcohol plus another drug usually adds up, it does not cancel out.
