Global Ganja Report

Cannabis has become a global industry, but obviously it is still limited by legal restrictions—and the fact that these increasingly vary from country to country further complicates things. Where is commercial cannabis going and where is it coming from? And how is this likely to change as the international atmosphere further liberalizes?

Oakland-based cannabis industry research firm ArcView Group has released a new study, ambitiously entitled "The Road Map to a $57 Billion Worldwide Market." It provides a sweeping overview of recent progress and future prospects for legal or medical herb across the globe. But it also warns that, due to continued legal restrictions and bureaucratic overstretch, the market is in most areas bottlenecked from achieving its potential.

In a sure sign of changing times, the first cannabis-industry business has been listed on the NASDAQ stock exchange—raising clear questions about how long prohibition can hang on in the face of a burgeoning economic sector. Toronto-based medical marijuana producer Cronos Group won approval from the US Securities and Exchange Commission (SEC) to become the first cannabis company listed on NASDAQ, New York City's second biggest stock market, Bloomberg reported Feb. 26.

You know the times they are a-changing when Forbes magazine runs a headline predicting that the international market for cannabis will hit $31.4 billion within the next four years. This projection is based on  a new report from the Brightfield Group, a cannabis market research firm based in Chicago. Currently, the global market is estimated to be worth $7.7 billion, but a compound annual growth rate of 60% is foreseen as countries around the world liberalize their marijuana laws.

Here's some counterintuitive news for those who have been hammered all their lives with claims that cannabis causes memory loss. A new study by scientists at the University of Bonn, written up in the journal Nature Medicine, finds that aging mice treated with daily small doses of THC actually experienced a reversal of cognitive decline. That is, they started doing better on cognitive tasks, such as going though a maze. The researchers foresee potential cannabis-based treatment to fend off dementia. "If we can rejuvenate the brain so that everybody gets five to 10 more years without needing extra care then that is more than we could have imagined," said study leader Andras Bilkei-Gorzo.

German authorities just took the unprecedented move to allow a medical marijuana patient to cultivate at home. The obscurely named Federal Institute for Drugs and Medical Devices (BfArM) announced on Oct. 2 that a multiple sclerosis sufferer from Mannheim, in Baden-Württemberg state, will be permitted to grow a maximum of 130 plants a year. But the grow must be confined to an extremely restricted space in his bathroom. Terms of the permit stipulate that any leftover plants or harvested herb must be destroyed, and the buds must be kept in a "secure storage unit."

A new marijuana policy could make it legal for individuals to posses up to 15 grams (0.5 ounces) of cannabis in the German capital, making Berlin among the most cannabis-friendly in Europe.
