I worked about a decade for the Colorado State Dept of Health and Environment to modernize process such as the Drinking Water Compliance system. I automated the process of over 1 M certified samples from State Certified Water Samples each MONTH. If you expect it for your water (and many other services) why wouldn’t anyone expect it for a product with “CBD” on the label?
Medterra's dissolvable sleep tablets combine 25mg of CBD with 10mg of melatonin to provide a restful nights sleep. Simply place the tablet under your tongue before bedtime and allow it to dissolve before swallowing. Each tablet is scored to allow for the user to consume half (1/2) of a tablet if they are sensitive to melatonin. Tablets contain natural spearmint flavoring.

I think being safe to eat is a moot point. These are topical products. I don’t think anybody is buying to eat them. It’s just a marketing tactic. In regards to the chapsticks, unless you were trying to literally eat the chapstick I think whatever negligible amount may make it past your lips and into your mouth, would certainly not be a health concern from any of these products. What concerns me more is there is zero efficacy with all of these products. Do they just decide over breakfast how much CBD needs to be added for the dosage to work? It’s ridiculous that they are marketing it as safe to eat, and people are buying into that bs and providing no clinical studies or research at all. Just my 2 cents
