Which substance would present symptoms such as anxiety, dilated pupils, dry mouth, teeth grinding and increased heart rate?

• A. Butane Hash Oil
• B. Methamphetamine
• C. Heroin
• D. Marijuana

Answer: (B)

These symptoms signal stimulant intoxication, where the body’s sympathetic nervous system is highly activated by the drug. Methamphetamine increases the release of norepinephrine and dopamine, fueling heightened alertness and arousal. That leads to anxiety or agitation, dilated pupils from sympathetic drive, dry mouth from dehydration and reduced saliva, and jaw clenching with teeth grinding as muscles stay tense. The heart rate also rises as part of the same fight-or-flight response. Other substances don’t fit this exact pattern. For example, opioids tend to slow breathing and cause pinpoint pupils, while cannabis can cause anxiety and faster pulse but not the pronounced jaw clenching and dry mouth pattern so consistently. The combination of marked arousal, dilated pupils, dry mouth, bruxism, and tachycardia is most characteristic of a stimulant like methamphetamine.
