A study’s conducted by the World Health Organization, released in early July found that the USA is the has the largest percentage of population, among the 17 surveyed counties, that have used Marijuana at least one time.
The numbers for the top five are:
USA – 42.4%
New Zealand – 41.9%
Netherlands – 19.8%
France – 19%
Germany – 17.5%
The interesting thing is that the only other country even close to us is New Zealand, another country with similiar drug policies to ours. The Netherlands, where Amsterdam is located, has less than half as many who tried it and the study found they tend to try it as adults, not as teenagers like in the USA.
