What characterizes cannabis withdrawal symptoms?

The correct characterization of cannabis withdrawal symptoms is that they are limited primarily to heavy users. Research indicates that individuals who have developed a dependence on cannabis—typically defined as heavy users—are more likely to experience withdrawal symptoms when they reduce or discontinue use. These symptoms can include irritability, insomnia, decreased appetite, anxiety, and restlessness.

In terms of the other options, the symptoms of withdrawal can vary widely among individuals, so they are not always severe and debilitating. While some heavy users may experience significant discomfort, others may have milder symptoms. Extreme hallucinations are not a common withdrawal symptom associated with cannabis; such effects are more often linked to other substances, such as hallucinogens. Additionally, withdrawal experiences are not consistent for all users, as they can vary depending on factors like individual biology, frequency of use, and the presence of other substances. Thus, the emphasis on heavy users underlines the idea that those who habitually consume cannabis are most likely to notice and report withdrawal symptoms upon cessation.
