Quebec tabled a law on Thursday that imposes a strict framework for the consumption, sale and distribution of cannabis.

The draft legislation focuses on potential social, health and safety problems that could follow the legalization of social use cannabis. Under the draft, there will be zero tolerance for driving while high and growing-your-own cannabis.

The province’s Liberal government will authorize police to test saliva samples from drivers and allow police to suspend anyone driving with a trace of cannabis or illicit drugs for 90 days.

Quebeckers are the ones who are the most uncomfortable with social cannabis legalization in Canada. On Wednesday, the Quebec government asked Ottawa to extend the July 1, 2018 deadline for legalization.

An initial 15 stores will be open by July 1, and there will be 150 sales outlets the following year, which will be allowed to sell dried and fresh cannabis, as well as cannabis oil.

“There are people who consume cannabis. We can’t avoid it. We can’t pretend it doesn’t exist,” Quebec Public Health Minister Lucie Charlebois said. “The proposed measures aim to limit risk and mischief linked to abuse of this substance and to fight the trivialization of this product. We will be prudent and restrictive from the start.”

Her colleague, Finance Minister Carlos Litao, called cannabis a “dangerous substance” that has only profited organized crimes for years.

“Do I like drugs? No,” Charlebois said. “Do we need to act? Yes. Unfortunately they are a reality we have to deal with and which we cannot ignore.”

The plan wants to get people to buy the drug under the law and government supervision. Quebec, she said, is not interested in expanding the consumption of cannabis or using sales to generate money for the government.

The bill omitted a sales price because Ottawa and the provinces have yet to agree on the level of excise taxes to impose on cannabis sales, but Quebec estimates it could earn between $30 and $40 million a year in excise taxes off sales and another $60 million in provincial sales taxes.

A legislature committee will start examining the bill Nov. 28, and it is unlikely the law will be adopted before the legislature recesses for Christmas break, in which case the debate would pick up in February.
