Note: Sample sizes differ for perceived harm (n=12,824) and content of last e-cigarette (n=8,887). Perceived harm was asked of a random subsample of pupils, whereas content of last e-cigarette was asked of a sample of ever users only. Both samples include gender non-response (n=256, 2.0%; n=218, 2.5%)
