Which of the following is considered a motivational syndrome associated with marijuana use?

The correct choice identifies personality changes as a motivational syndrome associated with marijuana use. This concept refers to the idea that chronic marijuana use can lead to a specific set of behavioral and psychological characteristics, often dubbed the "amotivational syndrome." Individuals experiencing this syndrome may exhibit a lack of motivation, diminished interest in activities they once enjoyed, and sometimes changes in their overall personality, appearing more lethargic or disinterested.

Personality changes can reflect broader cognitive and emotional shifts that might accompany continued use of the substance. For instance, users might find themselves less goal-oriented or engaged in interpersonal relationships, suggesting a reduction in initiative. These personality alterations can contribute to a cycle where the individual becomes increasingly reliant on the substance for social interaction and engagement, perpetuating the cycle of diminished motivation.

In contrast, short-term memory loss, physical dependence, and increased anxiety are effects that can occur with marijuana use but are not primarily classified as motivational syndromes. While they certainly can impact an individual’s overall functioning and quality of life, they do not encapsulate the broader personality and motivational changes seen within the context of the syndrome described.
