Note: This year's PDK / Gallup poll, conducted in May 2015, is a nationally representative web survey of 3,499 Americans, ages 18 and older, with Internet access — an additional 1,001 Americans ages 18 and older were surveyed by telephone. (nsba.org)
The researchers also note, as the data is drawn from web surveys, there will be biases inherent in the respondents — the ones who chose to respond may be more experienced in the drug culture, and as such may not be representative of the wider population, so it is important not to interpret the findings reported as prevalence estimates.
