What I mean is, there will always be some hard drug users, now from the discussion I understand some "hard" THC products exist, will this result in any kind of demographic change like the OP worried about, or is it just a new drug of abuse?
Just because these things exist, I don't think it automatically follows that they will get used by most people, or even more people than would have found some other destructive thing to do in their absence
Technology has massively changed how people consume cannabis - many people today may have never rolled or smoked a traditional joint ever. You can buy it in ready to load resin cartridges powered by a LiIon battery. Many of these things produce cold vapor that makes it staggeringly easy to smoke an enormous quantity. At least with a joint, there normally comes a point one's throat will probably not thank you for continuing... The cold vapor from many vaporizers is almost odor free too, meaning people can consume in places they couldn't previously.
The availability of vape pens also makes it REALLY easy to end up smoking way more than you would otherwise and as an easy way to start smoking in general. I smoke and enjoy the convenience of pens but they are perfect tools for increasing cannabis consumption in a population.
It is almost as if flower based cannabis is a gateway drug to these concentrated forms and I think it is really easy to go down that path as an already regular user. It's more economical, potentially better for you (less smoking) and now very easy to obtain.
I think the "overton window" of cannabis use is being shifted to the heavier end. Casual users will probably stay about the same but regular and heavier users will all shift to more or higher potency consumption.
