Canada is set to legalize recreational marijuana later this year, and many are excited for the new rules to finally come into effect. But if you're operating a cannabis business, you'll want to make sure you thoroughly check IDs.

The provinces of British Columbia, Nova Scotia, Saskatchewan and Newfoundland and Labrador have all passed laws that will allow authorities to hire teenagers in sting operations for cannabis businesses. All four provinces forbid the selling of cannabis to anyone under the age of 19 and also make it illegal for people under 19 to attempt to purchase marijuana, unless they're involved in these sting operations.

Similar programs are run throughout Canada for tobacco and liquor sellers, so it's not a case of cannabis being singled out by authorities but rather simply extending their current policy to include marijuana.

The states of Oregon and Colorado have similar programs that they run as well where they send underage kids into dispensaries to see if they're following the rules. According to the data published by those states, the vast majority of cannabis businesses comply with the law.

TheĀ Saskatchewan policy will actually be very similar to the one used in Oregon. The teenagers hired for the sting operations will need to use their real IDs, not a fake that says they're older than they really are, and they're not allowed to lie if questioned by the business owners.

Unfortunately for the teens, we're guessing they have to give back the cannabis if they're somehow able to actually trick the business into letting them buy it.
