According to Stuart Titus, the CEO of Medical Marijuana, Inc. (NASDAQOTH: MJNA), a Southern California-based provider of industrial hemp products, legalizing medical marijuana in Mexico represents a “$1 billion to $2 billion opportunity” in cumulative revenue over the next decade, according to an interview with Fortune . Of course, Medical Marijuana is no stranger to operating in Mexico. HempMeds Mexico, which is Medical Marijuana’s distribution branch in the country, was the first company to be allowed to import cannabis products into Mexico (non-psychoactive cannabidiol products, not THC). The bill currently working its way through Mexico’s legislative branches will merely make the infrastructure Medical Marijuana has laid in Mexico all the more effective — and potentially profitable. Mexico’s medical marijuana legalization efforts also come shortly after Prime Minister Justin Trudeau of Canada introduced a bill to legalize recreational weed. The demand for legal pot, be it medical or recreational, is exploding right before investors’ eyes, and producers with the capacity to expand their operations could benefit in a big way.

In Canada, the three largest medical cannabis producers, marijuana Canopy Growth (NASDAQOTH: TWMJF), Aphria (NASDAQOTH: APHQF), and Aurora Cannabis (NASDAQOTH: ACBFF), have all been hell-bent on increasing their production capacity. Canopy Growth took to the acquisition route and acquired Mettrum Health earlier this year, boosting its current growing capacity to 665,000 square feet across six licensed facilities.
