Cannabis intoxication is diagnosed when there is recent use and how many physical symptoms within 2 hours, plus what else?

• A. 1 physical symptom with no behavioral changes
• B. Recent use and 2 or more physical symptoms within 2 hours, plus clinically significant behavioral or psychological changes
• C. No behavioral changes
• D. Two hours after use only 1 symptom

Answer: (B)

Cannabis intoxication is diagnosed when there has been recent cannabis use plus a cluster of signs that point to intoxication within a short window, along with noticeable behavioral or psychological changes. Specifically, you need two or more physical signs within about two hours of use, and these occur together with clinically significant behavioral or psychological changes. The signs can include conjunctival injection, increased appetite, dry mouth, tachycardia, impaired motor coordination, slowed reaction time, impaired judgment, or anxiety/euphoria, among others. The behavioral or psychological changes—such as euphoria, anxiety, paranoid thoughts, impaired functioning, or social withdrawal—are essential to meet the diagnosis. The two-hour window ties the signs causally to cannabis use. That’s why the option describing recent use plus two or more physical symptoms within two hours plus clinically significant behavioral or psychological changes is the correct choice.
