Cannabis Use in the Netherlands
"The figures for cannabis use among the general population reveal the same pictures. The Netherlands does not differ greatly from other European countries. In contrast, a comparison with the US shows a striking difference in this area: 32.9% of Americans aged 12 and above have experience with cannabis and 5.1% have used in the past month. These figures are twice as high as those in the Netherlands."
