I don't think so. If the government did this they would be inviting black market commercial growers back into the setup

After legalisation I would look forward to:

1. Consistent quality products
2. A guide to strength (e.g. % THC) this would be great
3. Genetic History of the plant - helps meds users find high CBD Indica strains and someone who wants to try it out a light Sativa etc etc
4. Regulated growth, prep (curing) and distribution - so that means controlled use of pesticides and proper curing plus decent storage = good product. Plus I get to know what went into it.
5 A regular supply of quality product.

OK you can do some of the above by growing your own too

If cannabis were legalised into a commercial product the results could potentially be dynamite to the average smoker.

If the government fucked it all up we would all go back to the black market anyway - they know this. They would have to create a quality product to compete. If it were managed properly with the long game in mind then we could look forward to being to pick and choose like kids in a candy shop.
