While most wealthy economies are still stagnant, in decline or disrepair, the Canadian economy has outpaced all comers and will avoid the possibility of a double-dip recession that continues to haunt the US. But beyond the chorus of self-congratulatory backslapping coming from Ottawa, there has emerged a new and immediate threat of economic crisis that is being willfully ignored by Canadian politicians.

This November, in an effort to increase tax revenue, California will hold a referendum on whether or not to legalize the cultivation and use of marijuana. If passed, the change in law would be devastating to the Canadian economy, halting the flow of billions of dollars from the US into Canada and eventually forcing hundreds of thousands into unemployment.

Over the past 20 years, Canada has developed a substantial and highly profitable marijuana industry that is almost completely dependent on the US market. Between 60 and 90% of the marijuana produced domestically is exported to the US via cross-border smuggling operations. It’s exactly like the alcohol prohibition of the 1920s, only far more sophisticated and more profitable. The establishment of a legal industry based in the US would likely cripple these exports overnight.
