C Correct answer
Explanation
Cocaine is a powerfully addictive stimulant drug made from the leaves of the coca plant. It produces short-term euphoria, in addition to potentially dangerous physical effects like raising heart rate and blood pressure. Cocaine is a strong central nervous system stimulant that increases levels of the neurotransmitter dopamine in brain circuits regulating pleasure and movement.
Barbiturates are a group of drugs in the class of drugs known as sedative-hypnotics, which generally describes their sleep-inducing and anxiety-decreasing effects. Benzodiazepine use has largely replaced barbiturates in the medical profession.
Morphine is an opioid pain medication. An opioid is sometimes called a narcotic. Morphine is used to treat moderate to severe pain. Short-acting formulations are taken as needed for pain. Morphine is not for treating short-term pain just after surgery unless you were already taking morphine before the surgery. 
Chewing tobacco is very harmful for heart and blood pressure. 
Hence, the correct answer is option C.
