medibles 300 mgs questionable blackmarket edibles?

I got 3 packages of these edibles from a friend. Not a dispensary despite them looking kinda suspicious I ate one and honestly I can say I was pretty high not too high though like it was definitely the edibles because I didn't smoke all day and I was high for 5 hours. When I looked up the packaging I could barely find any information about them. It just seemed off that a dispensary would use brand names candies. It says 300 mg on the front of the cover on the back there is a normal warning about medical cannabis and that it contains thc. and there is 5 candies in the package. They taste like weed. And to my best knowledge it felt like what 60 mgs of thc would feel like. The candies look exactly like what they are labeled as the gummy worms look like gummy worms same for the south patch kids and watermelon slices. Are these just edibles some guy made maybe by putting a drop of thc on normal candies? Because it felt like a completely fine edible experience my friend told me he got them for 20$ a package. Any thoughts?
