Well it's been available for two days now and nothing horrible has happened.
Perusing a list of licensed retailers, I see that there are a couple about three hours from me, but I'm not going to be running out to buy my legal ounce. It's not part of my lifestyle, and that's where the doom sayers fail to recognize human nature.
See, for those of us who haven't been smoking pot recreationally, this change pretty much means... nothing. Just because it's legal doesn't increase the desire for it. And, anyone who is a pothead today was a pothead last week. Maybe some people will try it because it's legal, but I foresee far more tourist dollars from experimenters than in-state.
On top of which, the current retailers were already medical marijuana dispensaries, since the licensing regulations gave them a head start (like, no straight retail licenses effective until next year) and they'll be desperately trying to make as much money as they can before it becomes more widely available. Unfortunately the only real advantage they have over the illegal market is the availability of the alternate delivery methods... tinctures, candies, sodas, and other sundry consumables.
The reason I say that is because with a 40% tax they can't match "black market" prices. See again, anyone who is a pothead today was a pothead last week, they're not going to have a problem with buying it illegally, since they've become quite accustomed to breaking that particular law already.
Meanwhile, the press is painting this as an amazing experiment in legal pot, watched worldwide. Holland, however, is sitting back munching brownies and saying "I told you so, man. Want some recipes?"
Seriously, this is only an experiment in public opinion, since the availability of marijuana, in large part the usage, and for sure the methodology is not actually going to change for those toking up.
There aren't many retail stores available either, but never fear, Colorado residents. If you want to exercise your new found freedom to spark up a doobie, you don't have to drive for hours to acquire your legal ounce... You can grow it!
Six plants per person, says the state law, grown in an enclosed and locked space, with three of them being allowed to be flowering at any one time. Harvest must be kept in the locked enclosed space as well, but you can give your friends up to an ounce at a time, if they're also Colorado residents.
Out of staters are only allowed to have a quarter of an ounce at a time, and are reminded that many ski areas are located on federal lands, where pot is still illegal.
If you have a burning need to experience the mind altering joys of "puff puff pass" by all means come visit. Unfortunately since my county voted against allowing retailers, you won't be giving your tourist dollars to my area, but what the hell, rock the ganj anyway if you want.
