NL as well, a whole section of drug stores (that also sell things like shampoos, hair dyes, makeup, toys, ramen noodles, candy... they diversified) dedicated to melatonin, CBD oils and products, probably some others too.

I want to believe it's because they've been thoroughly tested to not be harmful, since they don't even have the leaflet that's mandatory with drugs / medication listing all the side effects and whatnot.
