With the recent legalization of cannabis edibles in Canada, physicians and the public must be aware of the novel risks of cannabis edibles, argue authors in a commentary in CMAJ (Canadian Medical Association Journal): http://www.cmaj.ca/lookup/doi/10.1503/cmaj.191217
Although edibles are commonly viewed as a safer and more desirable alternative to smoked or vaped cannabis, physicians and the public should be aware of several risks related to the use of cannabis edibles.”
Drs. Jasleen Grewal and Lawrence Loh from the University of Toronto, Toronto, Ontario
Cannabis edibles take on average four hours longer to produce noticeable effects in comparison to inhaled cannabis, which can increase the risk of overconsumption. With effects lasting up to 8 hours, edibles can also lead to a longer period of impairment compared to inhaled cannabis. While federal regulations have standardized the presentation of dosing information, the authors warn that “individuals’ responses to different products may vary and overdosing may still occur, with cannabis-naive individuals particularly at risk.”
At particular risk are children and pets as many edibles look like candy and other appetizing food and drink. Other vulnerable groups include older people and youth; of note, a recent Canadian report found that youth believe cannabis edibles have positive effects on sleep, mood and anxiety, which actually runs counter to what is seen in evidence.
“Physicians should routinely question patients who ask about cannabis about their use or intended use of edible cannabis products so that they can counsel these patients regarding child safety, potential for accidental overconsumption and delayed effects, and potential for interactions with other substances such as alcohol, benzodiazepines, sleeping aids and opioids,” caution the authors.
Population-level monitoring, and evaluation of the effects of legalized edibles will ensure that regulations are best able to protect children, youth, seniors and other age groups from health effects related to the consumption of cannabis edibles.

Coronavirus Live Updates: Some Carriers Might Show No Symptoms, Researchers Say – The New York Times
Here’s what you need to know:
People without symptoms could be spreading the virus, researchers say.
The medical journal The Lancet published a study on Friday suggesting that people infected with the new coronavirus might be able to spread it even if they do not have flu symptoms.
Researchers studied a family of seven in the Chinese city of Shenzhen, five of whom had traveled to Wuhan, the center of the outbreak. Two of them came into contact with an infected relative in a hospital there. Testing conducted days later, after they flew home, found that six members of the family had the coronavirus, including one who had not gone to Wuhan.
One infected family member, a child, had no symptoms, suggesting that people with the virus might be spreading it without knowing that they have it, the study found.
“It shows this new coronavirus is able to transfer between person to person, in a hospital setting, a family home setting, and also in an inter-city setting,” Yuen Kwok-yung, an author of the study, said in an interview. “This is exactly what makes this new disease difficult to control.” Dr. Yuen characterized the disease as “asymptomatic walking pneumonia.”
The researchers cautioned that the study was limited to early cases of the virus, and that it was difficult to assess risk factors at this stage. But they stressed the importance of quarantining patients as early as possible, given the early signs of asymptomatic transmission.
Another study in The Lancet found that symptoms of early coronavirus cases showed similarities to SARS, the respiratory disease that killed nearly 800 people worldwide in an outbreak that began in China in 2002. Those symptoms included fever, dry cough and shortness of breath.
Fifteen new deaths were reported in Wuhan.
Fifteen more people have died in the city of Wuhan, the capital of the Chinese province of Hubei and the epicenter of the coronavirus outbreak, the provincial health authorities said.
The new figures, announced early Saturday, represented a nearly 60 percent jump from the previous death toll of 26.
Just three of the 41 deaths reported over all have taken place outside of Wuhan: one in another city in Hubei Province, one in Hebei Province, and one in Heilongjiang, near the Russian border.
The new victims ranged from 55 to 87 years old. Eleven were male, and four female.
Nationwide, more than 400 new cases of the virus were diagnosed, officials said early Saturday, bringing the total number of confirmed cases in China to nearly 1,300.
All of the reported deaths have been in China, but travelers have spread the virus to numerous other countries. Cases have been confirmed in Australia, Malaysia, Nepal, Vietnam, Singapore, Japan, South Korea, Taiwan, Thailand, France and the United States.
China is building a hospital to fight the outbreak. Projected completion time: 10 days.
A fleet of earth movers tore into the soil. Workers and trucks swarmed around the site.
Under pressure to show an emphatic response to the coronavirus outbreak, the Chinese authorities have begun building a hospital in Wuhan, the center of the outbreak. They hope to complete it in 10 days.
The Wuhan government on Friday said it was building the temporary Huoshenshan Hospital to treat patients with the previously unknown virus that has sickened hundreds in the city. The hospital will have space for 1,000 beds and is expected to be completed by Feb. 3, according to a local media report posted to the Wuhan government’s website.
The authorities met on Thursday evening to come up with a plan and a design for the makeshift hospital, which is modeled after a facility built by the government of Beijing in 2003 during the SARS outbreak.
The authorities dispatched 35 backhoes, 10 bulldozers and eight road rollers to a 270,000- square-foot plot in Wuhan’s Caidian district, the report said. The land sits on the northwestern bank of the Yangtze River, it said.
The Communist Party long ago realized that its authoritarian rule over China came with trade-offs. In times of disaster, for example, the government could quickly be blamed for causing the problem or responding slowly.
As some people online question the government’s response to the deadly outbreak, building a hospital in less than two weeks could serve as a symbol of Beijing’s commitment to address the outbreak head-on.
Tracking Where the Coronavirus Has Spread
The virus has sickened more than 1,000 people in China and a handful in other countries.
Chinese-Americans are scrambling to help.
For people in the United States with close ties to China, the outbreak has brought unexpected worry, disappointment and scrutiny. Some in the Chinese-American community have had their Lunar New Year holiday plans waylaid, as travel schedules for the coming week and beyond get interrupted.
Some are gearing up for the outbreak to get worse. Hardware stores and pharmacies around the United States are selling out of masks that could help prevent the spread of the disease. In the New York City neighborhood of Flushing, masks have been sold out for much of the week.
Chinese-Americans networking with their friends and family in China have scrambled to send aid. One woman in Los Angeles has amassed 20,000 masks to ship overseas.
Sean Shi, of Issaquah, Wash., said he shipped several boxes of masks to China in a friend’s luggage, with hopes that the masks could reach friends in the Wuhan area as soon as possible. Later in the day, Mr. Shi was back at a local hardware store, buying another 46 masks for some of his former peers at Wuhan University.
“We understand it’s a tough situation over there — the panic, the shortage of equipment,” Mr. Shi said. “We just realized the situation is very serious — more serious than we thought.”

China coronavirus Death toll rises
Health officials in China say a coronavirus has killed 15 more people in the province of Hubei, where the outbreak first started.
There are currently 1,287 confirmed cases in China, 41 of whom have died.
It comes as China is begins celebrations of the Lunar New Year, one of the most important dates in its calendar.
Many events have been cancelled and a new hospital is being built in the city of Wuhan.
The virus has now spread to Europe, with three cases confirmed in France.
The first case was in Bordeaux, while the other two were in the Paris area, the French health minister said on Friday night.
And one case has been confirmed in Australia.
Chinese media outlets said the new 1,000-bed hospital could be ready within six days. A total of 35 diggers and 10 bulldozers are currently working on the site.
The project will “solve the shortage of existing medical resources” and would be “built fast [and] not cost much… because it will be prefabricated buildings”, the Changjiang Daily said.
Pharmacies in Wuhan have begun to run out of supplies and hospitals have been filled with nervous members of the public.
Symptoms seem to start with a fever, followed by a dry cough and then, after a week, leads to shortness of breath and some patients needing hospital treatment.
Around one-in-four cases are thought to be severe.
What restrictions are in place in Hubei?
Travel restrictions vary from city to city.
Wuhan is effectively on lockdown: all bus, metro and ferry services have been suspended, and all outbound planes and trains cancelled.
Residents have been advised not to leave, and roadblocks have been reported.
Ezhou, a smaller city in Hubei, shut its railway station. The city of Enshi has suspended all bus services.
And the rest of China?
City officials in the capital, Beijing, and Shanghai have asked residents who return from affected areas to stay at home for 14 days to prevent the spread of the virus, local media report.

Authorities have also shut major tourist sites including the Forbidden City in Beijing and a section of the Great Wall, and cancelled major public events in other parts of the country, including:
- Traditional temple fairs in Beijing
- An international carnival in Hong Kong
- Hong Kong’s annual football tournament
- All public Lunar New Year celebrations in Macau
Shanghai’s Disney Resort is temporarily closing, as are McDonald’s restaurants in five cities.
On Thursday, a coronavirus patient died in northern Hebei province – making it the first death outside Hubei.
Another death was later confirmed in north-east Heilongjiang province, more than 2,000km (1,200 miles) from Wuhan.
Earlier, when the death toll was 17, information from China’s National Health Commission said the youngest person who died from the virus was 48 and the oldest was 89.
But 15 of the 17 were over 60, and more than half suffered from other chronic diseases including Parkinson’s and diabetes. Just four were women.
What’s the global situation?
French Health Minister Agnès Buzyn said one of the French cases, a 48-year-old man of Chinese origin who had been visiting Wuhan, had been hospitalised in Bordeaux. Little was known about the second case, in hospital in Paris, except that the patient had been travelling in China.
It was likely other cases would occur in Europe, Ms Buzyn added.
She confirmed a third case, in Paris, later on Friday evening.
On Saturday, Australia reported its first case, a patient who is in hospital in Melbourne, after arriving from China last weekend.
Earlier on Friday a case was confirmed in Chicago, the second in the US.
Singapore confirmed its third case, known to be the son of another patient, also on Friday. Nepal recorded its first case on the same day.
Thailand has five cases confirmed; Japan, Vietnam and South Korea two each; and one in Taiwan.
The World Health Organization has not classed the virus as an “international emergency”, partly because of the low number of overseas cases.
“It may yet become one,” said the WHO’s director-general, Dr Tedros Adhanom Ghebreyesus.

Federal Government Increasing Measures to Monitor Wuhan Novel Coronavirus Risks at Canadian Airports, Including Pearson – Government of Ontario News
TORONTO — Today, Christine Elliott, Deputy Premier and Minister of Health, and co-chair of the federal-provincial-territorial health table, released the following statement on Ontario’s preparedness for the Wuhan novel coronavirus following a joint call with her federal and provincial counterparts:
“While there remain no confirmed cases of the virus in Canada, the federal government is putting in place enhanced screening and detection measures at Toronto Pearson International Airport to further protect the health of the public from the Wuhan novel coronavirus.
Today, I joined Patty Hajdu, Minister of Health for Canada, and my ministerial colleagues from each of the provinces and territories to share important information and further coordinate our joint efforts to protect the health and well being of all Canadians, including Ontarians, from the emerging issues of the Wuhan novel coronavirus. The federal government outlined their enhanced measures, which now include:
- Screening questions at border kiosks will now include questions about previous travel to Wuhan, China in the past 14 days. A positive response would trigger an enhanced screening process, including sending the traveller to a Canadian border agent for further questioning about their health status. The border agent will determine whether the traveller needs to seek immediate medical assessment and treatment and, if so, EMS will transport the traveller from the airport directly to hospital. This screening will be done in Vancouver and Montreal as well.
- Fact sheets are also being developed in English, French and Chinese for people who have travelled to China and are not currently exhibiting signs of illness. These fact sheets will outline the symptoms that individuals should watch for and any next steps should they experience symptoms, including seeking an immediate medical assessment.
The federal government’s enhanced screening measures build on Ontario’s robust and comprehensive protocols in place to actively monitor for, detect and contain any suspected cases of Wuhan novel coronavirus. The federal government’s measures will further support my ministry, in collaboration with Public Health Ontario, local health units, hospitals and health care providers, to monitor the Wuhan novel coronavirus and contain any cases, should one present in Ontario.
While the risk to Ontarians remains low, we will continue to be in close contact with the Public Health Agency of Canada and other jurisdictions to monitor this developing situation and safeguard the health of all Ontarians.
I’d like to thank all our partners for their on-going efforts in responding to this emerging situation. I want to reiterate our top priority will always remain safeguarding the health of the public, patients and care providers.”
