Purchasing edibles can be confusing in areas where there is still an unregulated cannabis market. The way to differentiate regulated vs unregulated edibles is two fold. First you will notice that regulated edibles come with an excise stamp affixed to its package and second you will notice that the maximum allowance for THC content is 10 mg per package.
The potency issue is very hot right now as many people want products that are higher in THC content as well you may notice that the purchasing limits on certain ingestible products is non-sensical. Health Canada is still learning how to manage potency and purchasing limits so you might notice that you can purchase quite a few powdered infuser packages with relatively high potency but only 5 CBD beverages. Confusing for sure so feel free to ask us for clarity.
