Combining drugs

8. Combining drugs

Combining different drugs may increase the intensity or completely alter the effect of a drug. It
is advisable for workers to seek advice from their doctor or pharmacist about any possible side
effects arising from mixing drugs.
Combining medication and alcohol may also alter the side-effects of medication and affect a
worker's ability to work safely. Sleeping tablets mixed with alcohol, for example, may impair
judgment or coordination.
Mixing illicit drugs that depress the central nervous system and alcohol can also increase the risk.
For example, combining cannabis and alcohol significantly increases the risk of accidents to higher
levels than occurs with either drug alone.
Further information about alcohol and/or other drugs and their effects can be obtained from the
Alcohol and Drug Information Service. See Appendix 1 for contact details.
