All eyes on Canada as first G7 nation prepares to make marijuana legal

From crime to health to business, Canadas decision to legalize marijuana is a grand progressive experiment that promises to answer a host of questions

When Canopy Growth opened its first cannabis factory in an old chocolate plant near Ottawa four years ago, it did so predicting a bright future. Canada had already legalized medical marijuana, and Canopy predicted full legalization for recreational use to be next.

What the company hadnt predicted, however, was the sudden flood of foreign visitors. Politicians and police authorities from Jamaica, Germany, Denmark, the Netherlands, Greece and Australia have all come knocking, as well as doctors from New Zealand, Brazil and Chile, along with groups of corporate investors and bankers so many that Canopy now sometimes splits up the groups according to their birthdays.

We knew wed have to give a lot of tours, so we just cut a window into the wall, said the company spokesman, Jordan Sinclair. We put windows in all of the doors.

Canada will be thrust even more directly under the international microscope on Thursday, when a vote in the Senate is expected to ratify Bill C-45, effectively making Canada the first G20 nation to legalize recreational marijuana.

Its going to be a bit of a science fiction experience for a while, said Benedikt Fischer, an expert on substance use at Torontos biggest psychiatric hospital. Its unique in the world, because its happening for the first time in a wealthy country. Its not like in the US, where there are these state experiments. Most people kind of ignore Uruguay. And so the world is really looking at this.

Governments, researchers and business leaders around the world all have their own reasons for keeping tabs. Legalization could affect Canadas crime patterns, health and countless other factors but exactly how, no one yet knows.

Each Canadian province plans to roll out its newly legalized market in a slightly different way, creating about a dozen mini-laboratories within one massive test case.

Even places that have already taken the legalization plunge are hoping Canada will solve some mysteries. After Colorado legalized marijuana five years ago, for example, organized crime reacted by ramping up supplies of black tar heroin, opiates and harder drugs, said Dr Larry Wolk, the states top public health official.

But Wolk says he is interested to watch that process unfold on a bigger scale in Canada, where the new law is expected to deal a much more significant blow to the black market. Any new mix of illicit drugs in the country could have new effects on public health.

Whats the impact of marijuana legalization on the opioid crisis? he asked as an example. Does it actually act as a substitute so that people can get off opiates for chronic pain? Is there a positive impact? Or is it a negative impact, because as a result theres more opiates in the black market? Is [pot] a gateway? We dont really have an answer.

One delicate balance for Canadian authorities has been guessing at what kind of pricing will be low enough to eradicate illicit sales yet not so low as to entice new users. Canadas finance minister, Bill Morneau, recently said the goal is keeping cannabis out of the hands of kids and out of the black market. That means keeping the taxes low so we can actually get rid of the criminals in the system.

One sign of success will be if Canada not only discourages underground sales, but converts illicit sellers to the new system, said Tim Boekhout van Solinge, a Dutch criminologist.

What I am mainly following is who will be the new legal growers, and whether authorities manage to get some of the illegal growers to become legal growers, he said.

Each country around the world that has debated whether to relax cannabis laws has had its own priority in mind: from generating revenue to discouraging drug cartels. In Canada, the emphasis has been largely on public health. Cannabis will be sold in fairly plain packaging, and usually through government-run boards that already control liquor sales.

It wont be like buying Budweiser or branded alcoholic products, said Steve Rolles of Transform, a UK drug policy thinktank. Its going to be more like buying pharmaceuticals from a chemist.

Still, its hard to know whether Canada, or any similar western country, will be able to stick to that public-health focus, he said.

We have concerns that the lessons from alcohol and tobacco wouldnt be learned, and we might see overcommercialized markets in which profit-making entities would seek to encourage more use and could encourage risky consumption behaviours, he said.

So far, Canada has allowed a few major players to dominate the industry, and their influence remains to be seen, said US marijuana industry expert Mark Kleiman.

You dont want to build up big vested interests that then resist any change, he said. If you have commercial industry in cannabis, theyre going to end up writing the laws.

For epidemiologists, Canada will provide the best-ever data sets on cannabis use.

Colorados health results have been encouraging, said Wolk. But overall, researchers lack solid data about cannabis use. Some key questions include addiction levels, how cannabis affects mental health, and effects on young people, said Israeli scientist Raphael Mechoulam, often called the grandfather of cannabis research.

About 10% of the users may be addicted less than alcohol or tobacco, he said. Some users, who are already prone to schizophrenia, may get the disease earlier. He said he is also keeping an eye on whether heavy use by young people may affect their central nervous system.

Another current Canadian health debate is how many people will be light, casual cannabis users, and how many will be heavy users.

The government still must decide how to approach products that are very potent in THC, the psychoactive compound in cannabis, said Mark Ware, a drug researcher and pain specialist who helped lead Canadas federal taskforce advising the new legislation. Black-market sellers have produced increasingly strong concentrates, he said.

Those have not been the subject of studies up until recently, so the question of whether to regulate those, allow them in whatever context, and then be able to study their impacts on health, that would be very important, he said. But once theyre out there, its very hard to put them back in the box again.

Canadian police, meanwhile, will grapple with how to crack down on cannabis-impaired driving. Thats already a struggle around the world, regardless of marijuanas legality, said Rolles. But its much more difficult to measure impairment from cannabis than from alcohol, and enforcing a legal limit will prove tricky.

Meanwhile, many investors have already made huge profits from cannabis stocks, and a big question for them is whether the bubble bursts or the value keeps rising.

Theyre waiting to see if the skys going to fall, said Sinclair of Canopy. One of about 100 Canadian legal producers of medical cannabis, the company owns a third of the medical market, began trading on the Toronto stock exchange in 2016 and last month became the only cannabis producer on the New York stock exchange.

[Investors] are waiting to see if all the stigma and all the demonization of this product thats built up in 90 years of prohibition is true, Sinclair said. Its on us to demonstrate that its not.
