I've never used cannabis, and I certainly couldn't be bothered to grow it even if it was legal. Nor would I be interested in smoking. But I might try it in edible form if only just to have experienced it.
(And this is not down to lack of access - despite never having tried cannabis, I'd have no problem getting hold of some today if I suddenly decided I had to try it, which shows just how much of a total failure criminalisation of it has been)
I definitively agree with you. There'll be plenty of people who'll want to grow their own, but also plenty of people like me or somewhat more interested, that'd be interesting in trying or indulging in it now and again, but who's not interested in tending for a plant (just like I'm not growing my own vegetables...), not interested in smoking, and not interested enough to pay attention to how to find a good quality product, who'd prefer to be able to just recognise a large brand that'd be a sign of sufficient quality and trust.
For that kind of market segment price matters less than recognition - I'd happily pay a "not having to spend time researching what to look for on the internet" premium of 100% or more if I at some point decide to try, the same way I drink alcohol so rarely that when/if I do I stick to a handful of well known brands that I'm comfortable with.
