Don’t pay for pot with plastic, says Canadian Privacy Commissioner Daniel Therrien, if you want to ensure you don’t run afoul of authorities in other countries.

The statement was released in conjunction with new guidelines meant to help both cannabis retailers and purchasers understand their rights and obligations under the law.

Therrien advises those who sell weed (legally and above board) to record as little information as possible about their customers and consider using email addresses, as opposed to names, in their databases.

Buyers are advised not to provide more personal information than necessary when purchasing cannabis and to “only purchase cannabis from those who keep your personal information in Canada.”

Some might venture to say that it’s a shame how many dispensaries in Toronto were forced to close once weed became legal in Canada. Ironically, those dispensaries may have been safer to purchase from than the government’s own website for people who travel outside the country.
