This has not been a very good year for the electronic cigarette and vaping industry, which is enduring a withering attack from regulators concerned about teenage use of the devices. Having declared it an "epidemic," the Food & Drug Administration is clamping down on manufacturers, proposing to ban almost all flavors, and warning people against any vaping at all as a mysterious lung illness sickened and injured thousands and killed dozens of users.

Emma Alter realized something was wrong with her King Charles spaniel Maggie when she turned down a cookie.

They’d gone to the dog park in Toronto where Alter, 31, can only assume Maggie got into something she shouldn’t have. Two to three hours after the walk, the dog had rejected the treat, could barely stand up and was swaying with a “weird head bobble.” Alter rushed to an emergency veterinary clinic.

Regular cannabis use has risen more quickly among people with depression, and they’re less likely to perceive it as risky, compared with people who aren’t depressed, a U.S. study suggests.

Researchers examined data collected from a total of almost 729,000 people aged 12 years and older between 2005 and 2017, including any prior-month cannabis use and any depression experienced over the previous year.

By the final year of the study, about 19% of people with depression reported at least some cannabis use, compared with 8.7% of individuals without a recent history of depression. In 2005, about 10.2% of people with depression and 5.7% of individuals without depression used the drug.

Elizabeth Warren's campaign is hitting back after a Miami college student claimed a marijuana conviction disqualified him from working on her 2020 Presidential campaign. 

Nicholas Dore, 20, took to Twitter on Monday, sharing a string of tweets, which went viral, claiming he was offered a paid position on Warren's team. But he said the offer was revoked following a background check.  

Coming into 2019, marijuana stock investors had a lot to look forward to. Canada had become the first industrialized country in the modern era to legalize recreational cannabis in Oct. 2018, derivative pot products were expected to hit Canadian dispensaries later in 2019, and a number of U.S. states appeared to be on the verge of adult-use legalization. This was supposed to be the year that cannabis stocks turned the corner to profitability and really matured.

Unfortunately, this vision hasn't been anywhere close to reality for the weed industry in 2019.

In just a matter of days, we'll be closing the curtain on 2019, which turned out to be an incredibly good year for the broad-based markets, and an abysmal year for marijuana stock investors.

Everything began well, with cannabis stocks leading the charge throughout the first quarter. But the wheels, and everything else that wasn't welded on, soon fell off the wagon. Persistent supply issues throughout Canada, high tax rates in a number of recreationally legal U.S. states, and a resilient black market have made investing in pot stocks particularly painful in 2019.

A state-appointed council has determined that trace amounts of some pesticides, heavy metals, residual solvents, and microbial growth are safe in medical pot — even as some argue there isn't enough science yet to determine appropriate cannabis safety standards.

The Arizona Department of Health Services put the medical marijuana testing advisory council together in September as a requirement of the Arizona law that will mandate testing starting in November 2020. The group finalized its recommendations on December 23.

Coca-Cola Co. is dousing speculation that it’s getting into the cannabis business.

Speculation surged after a video posted to YouTube — since deleted — by a user with the screen name “Gabor the Blind Guy” showed a Coca-Cola can with a childproof lid.

The man in the video says that his father is a head engineer for a company that “produces bottling and capping machines for many major pharmaceutical and food companies.”

He then says that Coca-Cola is planning on debuting a new line of its classic drink in Canada that will feature CBD extract, the non-psychoactive ingredient in marijuana that treats pain but doesn’t get you high.

In less than a week, Illinois will allow recreational marijuana.

But there are loopholes.

CBS 2’s Chris Tye has the loose ends you may have missed.

Most of the questions about weed first require answers about in what form it’s being consumed.

Question 1:  How much can I have?

Thirty grams of weed in flower form is the max, which is typically somewhere between 30 to 50 joints worth. A gram is roughly the weight of a paperclip.

If consuming cannabis concentrate – think oil cartridges and medicated muscle creams – then five grams is the cap. If it’s edibles, like brownies or gummies, then 500 milligrams is the most you can have. While it can wildly vary, that’s usually 50 edibles worth.
