Even as health officials recommend that medical marijuana users avoid vaping products, medical marijuana companies say their products are safe.

In another landmark shift, as California’s cannabis industry evolves from an underground movement to a regulated market, state rules now require permit holders to undergo extensive safety training from the state’s arm of the federal Occupational Safety and Health Administration (OSHA).

In the four states where recreational marijuana was legal by 2016, there was a small uptick in cannabis use disorder among adults and teens, and a general rise in use by adults, a new study suggests.

Researchers looking at data on cannabis use between 2008 and 2016 found that rates of problematic use among teens and adults over age 26 rose faster in states where recreational marijuana had been legalized than in other states, according to the report published in JAMA Psychiatry.

Vape pen cartridges are very popular in the United States, however, they are somewhat of a novelty in other countries. That is likely to change in the future as vape pen cartridge technology spreads to other markets around the globe.

For those that are unaware of what a vape pen cartridge is, it’s a cartridge filled with a cannabis concentrate oil. 

The cartridge attaches to a battery that heats up an element or wick inside of the cartridge, and that creates a cannabis vapor that the consumer inhales.

For many consumers, a vape pen cartridge is preferred over smoking cannabis since it’s so convenient, discrete, and yields significantly less odor.

Since this time last year, the number of medical marijuana patients in Florida has more than doubled.

In fact, the state of Florida is the second-fastest-growing medical marijuana market in the country, according to a recent study done by Marijuana Business Daily.

In November 2016, medical marijuana became legal for Florida residents, but, despite the obvious upward trend, many in the industry say there is still a lot of misinformation about it.

CBS4’s Karli Barnett breaks down the facts and learned the process of accessing medical marijuana.

The U.S. Food and Drug Administration has approved a medical marijuana clinical trial led by the Yale University School of Medicine. Researchers say it’s the first of its type to be run on human subjects.

Cori Alicea has been using medical marijuana since she was diagnosed with stage 4 brain cancer in 2014.

“It helps me with every physical ability that I have, with talking and doing everything. My right side was completely numb after having my seizures and my surgeries from the craniotomies. This medicine has made it so that I am able to live my daily life.”

Western Australia’s McGowan Government has announced changes that will make it a little easier for patients in the state to access medicinal cannabis products.

Previously, patients would need a referral to a specialist by a GP in order to access medicines, but now a GP will be able to prescribe where the patient is over the age of 16, isn’t drug dependent and doesn’t have a history of drug use. In those cases, specialist approval will still be required.

A quarantine was ordered for most marijuana vaping products in Massachusetts Tuesday, extending the state's efforts to control vaping products amid a nationwide epidemic of lung injuries.

Exempt from the quarantine are medical marijuana products designed specifically for devices for medical marijuana flower vaping, the state Cannabis Control Commission said. Massachusetts' ban on vape-related products for medical marijuana users was lifted as the quarantine went into effect.
