So statistical significance is measured by time? Interesting. How long a time period will yield statistically significant conclusions?
Well I can tell you 60 years certainly yielded sufficient conclusions in the case of China. At needle park (Platzspitz Switzerland) it only took a few years.
Irrelevant evasions and a big graphic - very impressive.
No, you can't answer it and so you dismiss it. YOU have a big problem with the UGLY REALITY of your ideas. Denial is not just a river in Egypt.
The Platzspitz experiment was a test of YOUR IDEAS. They failed miserably. Legalized Opium was a much larger and much wider test of YOUR IDEAS. They failed massively.
What we can learn from real world experiments is that drugs kill people. Lots of people.
