Many years ago, yes, but I never bought incense without disclosure of the contained chemical(s). Such ones led to serious health complications, ER visits and worse. But I actually liked my self-made incense where we were using industrial hemp leaves and the cannabinoid UR-144. I guess the weed contained some CBD or related non-THC cannabinoids which smoothened the experience out. But somehow cannabinoids just aren't my drugs so I quit using such products.
They will continue selling incense with and without disclosure as long as the law doesn't prevent it. Like bath salt cathinones or room odorizers etc. It's a legal loophole they're exploiting, sadly this actually pushes selling stuff which seems to be herbal only and there's no legal way to list side effects, dosages etc.
Btw, let me welcome you to out neat little internet corner with blue light!
