Answer:
A and D
Explanation:
A. Sleep deprivation in turn downregulates dopamine receptors, which makes people more impulsive and vulnerable to drug taking.
D. When a person repeatedly uses drugs, he or she increases the risk for insomnia. This is because continued substance abuse affects the neurochemical functioning of the brain. It disrupts the brain’s sleep-regulatory systems and, in turn, disturbs the latency, duration, and quality of sleep for the user.
