CBD is very safe, as long as they’re made by reputable brands and come in a sealed package. This goes for everything, but I’m simply saying that buying CBD from your next-door neighbour might not be the best choice for safety reasons.
The same goes for CBD edibles. They are incredibly safe 9.5/10 times, and all you need to do is make sure they’re made with care and are free from solvents and chemicals (which you can do by checking a product’s third-party lab results).
