Mask illegal drug use
Using drugs from two or more drug categories simultaneously.
Examples of polydrug use are
Drinking while smoking weed, sprinkling PCP on a joint, Shooting up heroin laced with cocaine (speedball)
Neither drug produces an indicator of drug impairment, for example neither a CNS stimulant nor a narcotic analgesic will cause horizontal gaze nystagmus therefore, HGN will not be present.
One drug affects some indicator of impairment, and the other drug has no effect whatsoever on that indicator. For example alcohol will cause HGN but weed will not cause HGN. Therefore HGN will be present
Drugs from two categories both affect some indicator of impairment in the same way and these effects reinforce each other when combined. Example, CNS stimulants and hallucinogens both cause pupil dilation, so the pupils will be dilated
Drugs from two categories may produce some effects that are exact the opposite, but, in combination, the effects are difficult to predict. Example, cocaine dilates pupils, heroin restricts them, The eyes may be dilated, constricted or normal.
