Question

question 8
the following drugs are addicting both psychologically and physically except:
marijuana
all these are psychologically and physically addictive
hallucinogens
narcotics

Explanation:

Hallucinogens primarily cause psychological effects like altered perception and thought. While they can have psychological dependence, physical dependence (withdrawal symptoms like those seen in opioids (narcotics) or some substances with physical withdrawal) is not a characteristic feature. Marijuana can have some physical withdrawal (mild compared to some) and psychological aspects. Narcotics are known for both physical and psychological addiction. Since the question asks for the one that is not (as others have more of both), hallucinogens fit.

Answer:

Hallucinogens
