Which one of the following is the correct statement regarding the particular psychotropic drug specified?
A Morphine leads to delusions and disturbed emotions
B Barbiturates cause relaxation and temporary euphoria
C Hashish causes alter thought perceptions and hallucinations
D Opium stimulates nervous system and causes hallucinations

Detailed Solution

Psychotropic drugs are grouped according to their effect on the nervous system.
Hallucinogens such as LSD, mescaline and the products of the hemp plant Cannabis sativa (hashish, charas, ganja, marijuana) alter thoughts, feelings and perceptions and cause hallucinations. So the statement about hashish is correct.
Morphine is an opiate narcotic obtained from the latex of the poppy plant; it is a very effective sedative and painkiller (analgesic) and does not typically lead to delusions and disturbed emotions.
Barbiturates are sedatives and tranquillisers: they depress brain activity and produce feelings of calmness, relaxation and drowsiness (sleep), not euphoria.
Opium and its derivatives are depressants that suppress brain function and relieve pain; they do not stimulate the nervous system.
So the correct statement is that hashish causes altered thought perceptions and hallucinations.
