A person who consumes alcohol and drives risks driving while impaired, while the same person who smokes marijuana and drives also risks driving while impaired. Alcohol and marijuana act on different receptors tied to different brain systems, but use of both drugs together compounds the impairment. Why is this the case if the two drugs do not act on the same systems?
What will be an ideal response?
While each drug acts through different mechanisms, they each serve to slow reaction time. A decrease in reaction time while driving is a major cause of the problem of driving under the influence.
