You're right, my previous response was focused primarily on the United States legal system. Let me try to provide a broader perspective:

There have been similar cases related to allegations of falsified evidence or misleading claims in other countries that have criminalized marijuana. For example, in Canada's Le Dain Commission of Inquiry in the 1970s, some argued that the government made misleading claims about the harms of marijuana in order to support prohibition. In New Zealand, a government committee found that officials had distorted and exaggerated evidence about marijuana's risks in the lead-up to criminalization in the 1960s and 70s. And in the United Kingdom, some analysts have pointed to misleading statements and 'reefer madness' claims that shaped public perception of marijuana in the years leading up to criminalization.

However, I have not found publicly available legal cases in other countries that directly parallel the US case I mentioned, involving falsified signatures and testimony of doctors. The nature and extent of falsified evidence or misleading claims seems to vary in different national contexts. If there are specific countries or time periods you are interested in, please let me know and I can try to provide more targeted information. Does this help provide the broader perspective you were looking for?
