I think if it worked the same as alcohol, it would work well, for the most part.
Legal to grow and consume, but not to sell without a license.
Regulation is important as well.
Because like moonshiners selling bottles of methanol and killing people, cannabis needs regulation to be as safe a product as possible.
What of all the PGR's and heavy use of dangerous fungicides and pesticides, without following procedure?
That needs regulation.
Same with it's consumption. Because it's a psychoactive substance.
It's illegal to supply a child with alcohol. Same as it should be with cannabis.
The black market will always exist and good weed will always sell.
We need to be sensible with legalization, or we'll never get anywhere.
Imvho it's about compromise. There needs to be some.
