Colorado's pot market is about to get a lot bigger.
Starting Tuesday, anyone can apply for a license to open a recreational marijuana business.
For the past six months, only medical marijuana shops could apply to sell pot to the masses.
As the pot industry expands, there are growing concerns about public safety, especially when it comes to edible products. A pot brownie or cookie may contain nearly a dozen doses of marijuana.
Officials are trying to push restrictions because, in some cases, the consequences can be deadly. CNN's Ana Cabrera has more.

The Pope is speaking out against the worldwide trend toward legalizing recreational drugs.
He calls it a very, very bad idea.
At a drug enforcement conference in Rome, Pope Francis said, "drug addiction is an evil, and with evil there can be no yielding or compromise."

A 19-year-old Texas man is facing serious prison time for hash brownies.
Marijuana may be legal in some parts of the country, but in others, laced-baked goods could land you in jail for the rest of your life.
The issue is the brownies were made with hash oil, which is considered much more serious than marijuana in Texas.
So does the punishment fit the crime?

It will be another couple of weeks before it's actually in use, but a pot vending machine has been unveiled in Colorado.
It got CNN's Jeanne Moos thinking about vending machines of the future as well as the ones that have gone up in smoke.
Editor's note: Don't miss "Weed 2: Cannabis Madness: Dr. Sanjay Gupta Reports," at 10 p.m. ET on Tuesday.
(CNN) - It's been eight months since I last wrote about medical marijuana, apologizing for having not dug deeply into the beneficial effects of this plant and for writing articles dismissing its potential. I apologized for my own role in previously misleading people, and I feel very badly that people have suffered for too long, unable to obtain the legitimate medicine that may have helped them.
I have been reminded that a true and productive scientific journey involves a willingness to let go of established notions and get at the truth, even if it is uncomfortable and even it means having to say "sorry."
It is not easy to apologize and take your lumps, but this was never about me.
This scientific journey is about a growing number of patients who want the cannabis plant as a genuine medicine, not to get high.
It is about emerging science that not only shows and proves what marijuana can do for the body but provides better insights into the mechanisms of marijuana in the brain, helping us better understand a plant whose benefits have been documented for thousands of years. This journey is also about a Draconian system where politics override science and patients are caught in the middle.
Since our documentary "Weed" aired in August, I have continued to travel the world, investigating and asking tough questions about marijuana.
