Explanation:

Question 15

Depressants are drugs that slow down the central nervous system. Valium is a known depressant. Inhalants are inhaled substances, stimulants speed up the CNS, and opioids are pain - relieving but not defined by just slowing the CNS like depressants.

Marijuana is a plant - based drug that contains THC (tetrahydrocannabinol). Opioids are not plant - based with THC, stimulants have different effects, and club drugs are synthetic and not plant - based with THC.

Opioids are used medically as painkillers, and heroin and morphine are examples of opioids. Stimulants speed up the CNS, marijuana is for other effects, and depressants slow the CNS, not used primarily as painkillers like opioids.
