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.

TORONTO — As the new coronavirus claims more lives in China, health authorities in this country are trying to reassure Canadians that plans and procedures are in place to protect them.
While no cases have yet been confirmed in Canada, Dr. Peter Donnelly, with Public Health Ontario, said Friday that it is indeed “likely” the coronavirus, which comes from the same family of viruses as SARS, will arrive here.
However, Donnelly added that health officials are much better prepared now than they were in 2003 when SARS killed 44 Canadians. He noted communications are more robust, hospitals have better isolation facilities, and a reliable test is available to detect the coronavirus within 24 hours.
Health officials are also working with the National Microbiology Lab in Winnipeg to develop an even quicker test, and screening measures have been beefed up at major airports in Toronto, Vancouver and Montreal. In addition, everyone is being urged to practice good hygiene that helps prevent the transmission of all viruses — washing hands thoroughly, covering coughs and sneezes, and staying home if you’re sick.
Man in his 50s first possible case of coronavirus in Ontario – 680 News
A Toronto hospital is treating a patient suspected to be the first case of coronavirus in Canada.
Dr. Barbara Yaffe, the province’s associate chief medical officer of health, says a man in his 50s who had travelled to Wuhan, China – were the virus outbreak originated – returned to Toronto on Jan. 22 was taken to Toronto’s Sunnybrook Hospital on Jan. 23 and is now in a negative pressure room.
According to Toronto Public Health, the patient is listed in stable condition.
Ontario’s Chief Medical Officer of Health, Dr. David Williams, said the “risk to Ontarians is low” and the “system is operating as it should.”
“All appropriate infection prevention and control measures were followed by both paramedics and the hospital,” said Williams. “Toronto Public Health is conducting case and contact management and Ontario is in touch with our federal counterparts to help determine exposure to other individuals on the flights.”
Health officials say the man traveled from Pearson airport to a residence using private transportation. They add the man’s wife has not shown any symptoms of the disease at this point.
The safety and security of passengers and employees is our top priority. We continue to work in close collaboration with @GovCanHealth and @CanBorder to ensure that all proper measures are taken for all international arriving passengers. https://t.co/3WHUxKEP1I

In China, the virus has infected more 1,200 people and killed 41, reports say.
In an effort to control the spread of the illness, the Chinese government has locked down the city of Wuhan, home to over 11 million people.
Travel has been banned to and from the central-Chinese city. The government has also banned most vehicle use, including private cars, in downtown areas starting Sunday, state media reported. Only authorized vehicles would be permitted, the reports said.
Australia and Malaysia reported their first cases Saturday – four each – and Japan, it’s third. France confirmed three cases Friday, the first in Europe, and the U.S. identified its second, a woman in Chicago who had returned from China.
The new virus comes from a large family of what are known as coronaviruses, some causing nothing worse than a cold. It causes cold and flu-like symptoms, including cough and fever, and in more severe cases, shortness of breath. It can worsen to pneumonia, which can be fatal in some cases.
Here are key things to know following the first presumptive positive case of the coronavirus in Toronto:
WHAT IS IT?
Coronaviruses are a large family of viruses that most often cause mild-to-moderate upper respiratory tract illnesses including the common cold, but they can also lead to severe diseases. Some coronaviruses spread between animals, some pass between animals and people, and others go from people to people.
This new virus is different from the coronaviruses that cause Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS).
WHAT ARE COMMON SYMPTOMS?
This new virus has non-specific symptoms including fever, cough and difficulty breathing.
Typically, coronavirus infections manifest as the common cold. Symptoms can include runny nose, headache, cough, sore throat and fever. Young babies may contract gastrointestinal disease.
Severe cases involve pneumonia, kidney failure and even death.
WHAT SHOULD I DO IF I SUSPECT INFECTION?
Consult your health care provider as soon as possible if you are worried about symptoms or have travelled to a region where severe coronaviruses are known to occur.
If you have mild cold-like symptoms, health officials encourage you to stay home while sick and avoid close contact to help protect others. Cover your mouth and nose with a tissue when you cough or sneeze, and be sure to throw used tissues in the trash and wash your hands. Clean and disinfect objects and surfaces.

Health officials announce ‘presumptive’ case of coronavirus in Toronto – Global News
Ontario health officials have announced that a “presumptive” case of coronavirus has been discovered in Toronto, which if confirmed would mark the first instance of the illness in Canada.
In an evening press conference at Queen’s Park, officials said they were made aware of the case Saturday afternoon.
A man in his 50s tested positive for the virus but secondary testing at Canada’s National Microbiology Laboratory will occur to confirm the case.
The victim recently travelled to Wuhan, China, which is believed to be the epicentre of the outbreak.
His condition is stable and he is being treated at Sunnybrook Hospital, officials said.
“The patient was detected and immediately put in isolation,” Ontario Health Minister Christine Elliott said.
“Lab tests were conducted and at the earliest signs of a presumptive positive case, Toronto Public Health launched extensive case and contact management to prevent and control further spread of the infection.”
Elliott said officials are working to identify everyone who the victim was in contact with in order to contain the virus.
Officials said any close household contact “has been put into self isolation.”
“Ontarians can rest assured that the province’s integrated health-care system today is far more prepared to respond to any potential health risks than in the past,” Elliott said.
Coronavirus outbreak: health officials provide details on presumptive case in Toronto
“We will continue to diligently monitor this issue to ensure Ontario remains prepared to identify, contain, and treat any additional cases of this virus.”
Ontario’s Chief Medical Officer of Health Dr. David Williams said the patient arrived in Toronto on Jan. 22 after flying from Wuhan with a connection in Guangzhou, China.
Williams said the patient had a family member call 911, at which point they told officials about his symptoms.
“A pair of ambulance services went fully protected,” Williams said.
The man was transported to Sunnybrook hospital on Jan. 23.
Toronto Mayor John Tory responded to the news of the case in a statement Saturday evening.
“While we now have one presumptive confirmed case, our health officials are clear that the risk to residents continues to remain low,” he said in part.
“Toronto Public Health is continuing to work closely with provincial and federal health colleagues to actively monitor the situation and respond as appropriate.”
The illness has sickened more than 1,200 people and killed at least 41 in China.
Australia and Malaysia reported their first cases Saturday — four each– and Japan, its third.
France confirmed three cases Friday, the first in Europe, and the U.S. identified its second, a woman in Chicago who had returned from China.
