Researchers in Vancouver, Canada are seeking 1,000 cannabis dispensary clients for a study on the pros and cons of pot shops.

The B.C. Centre on Substance Use (BCCSU) is conducting the online survey to help inform the Canadian government ahead of the July 2018 cannabis legalization deadline.  

“We know [dispensaries] serve a pretty wide cross-section of people in Vancouver,” said BCCSU researcher M-J Milloy.

“[We want to] sample the full gamut of cannabis users in Vancouver to find out why they use cannabis, what the impacts are, and try and prepare for legalization.”

The researchers plan to follow up with study participants after legalization has gone into effect to explore how the change affected their cannabis use.

"[Legalization] is the biggest experiment in drug policy in our lifetimes," he said. "So it's important we try and get it right, and as scientists, to observe what's going on."

You can join the survey by getting a code from a participating dispensary. The BCCSU hopes to complete the first part of the survey by the end of the summer and release their findings by January 2018.
