Could it be that commercial weed that is everywhere, isn't as fresh as off the vine? It spends way longer in facilities, packaging, etc...before it gets to me?
Maybe the older black market weed that I used to get was more fresh....and hence more gooey.

They’re Both Dried
"Don’t get us wrong, both sticky weed and dry weed are both dried — meaning they’ve both been cut from the stem of the cannabis plant, hung in a cool, dry place, and allowed to…dry (the beginnings of the decarboxylation
process). The dry weed may have been left hanging longer, or it may have had fewer trichomes (or less resin) to begin with. The fact that it’s dry and not sticky doesn’t mean that it won’t get you righteously high. It just means that the dry weed might have a harsher smoke or that it might not have a full, tasty flavor like the sticky weed."
Gooey, sticky weed rules.
