Wonders will never end. I'm as shocked as you are. See the story below:
DENVER (Reuters) - The world's first state-licensed marijuana retailers, catering to Colorado's newly legal recreational market for pot, are stocking their shelves ahead of a New Year's grand opening that supporters and detractors alike see as a turning point in America's drug culture.
Possession, cultivation and private personal consumption of marijuana by adults for the sake of just getting high has already been legal in Colorado for more than year under a state constitutional amendment approved by voters.

But starting January 1, cannabis will be legally sold and taxed at specially regulated retailers in a system modeled after a regime many states have in place for alcohol sales - but which exists for marijuana nowhere outside of Colorado.
For the novelty factor alone, operators of the first eight marijuana retailers slated to open on Wednesday morning in Denver and a handful of establishments in other locations are anticipating a surge in demand for store-bought weed.

"It will be like people waiting in line for tickets to a Pink Floyd concert," said Justin Jones, 39, owner of Dank Colorado in Denver who has run a medical marijuana shop for four years and now has a recreational pot license.
Jones said he is confident he has enough marijuana on hand for Day One but less sure of inventory levels needed after that.
About 90 percent of his merchandise is in smokable form, packaged in small child-proof containers. The rest is a mixture of cannabis-infused edibles, such as cookies, candy and carbonated drinks.
"People seem to prefer smoking," he said.

The effect of this remains to be seen; I'm keeping my lips sealed for now.
I just hope this doesn't turn out badly.
