An overdose is more likely to happen in a novel environment for a drug user.

• A. It depends on the drug
• B. Not enough data
• C. True
• D. False

Answer: (C)

The concept being tested is how environment influences tolerance and overdose risk. When a drug user becomes tolerant to a drug, part of that tolerance is context-specific: the body learns to expect the drug’s effects in familiar surroundings and recruits compensatory responses in those cues. If the user takes the same dose in a novel environment, those contextual cues aren’t present, so the body doesn’t engage the same tolerance mechanisms. The drug can produce stronger effects than the user anticipates, raising the chance of overdose. This idea, often described as conditioned tolerance, helps explain why overdoses are more likely in new settings.
