• Puff count claims on disposable vapes are estimates, not guarantees, and often reflect lab testing under ideal conditions rather than real-world usage. In Illinois, where commuting patterns and usage habits vary, shoppers should compare the claimed puff count against the device's e-liquid capacity and battery life, and ask sellers how these numbers were derived. Recognizing the gap between marketing and label details helps adult consumers make more informed purchases.
• Puff count is an estimate, not a promise—real-world usage varies widely.
• Check the label for e-liquid volume and battery capacity, not just the puff count.
• Ask the seller how they test or derive the claimed puff count.
• Be wary of vague 'up to' numbers and claims that sound too clean.
• In Illinois, no specific puff-count law exists, but state labeling rules and FDA oversight apply.
