The coverage, which requires employers to pay a premium, extends
only to a handful of conditions as a last resort.
"It's not medical marijuana for any purpose," said Dave Jones,
senior vice-president of group benefits at Sun Life. "It's for
specific conditions and symptoms where the evidence is clear that
medical cannabis has enough value to outweigh risks."
Sun Life's cautious approach reflects concern across Canada's health
insurance industry over the potentially high costs of covering
medical marijuana - in many cases higher than established
pharmaceuticals - and thin clinical evidence for its efficacy.
Canada, a pioneer in approving medical marijuana, legalized
recreational use this summer. Canadian insurers' reluctance to cover
it suggests most patients here and elsewhere may continue to bear
most of its cost despite pending legalization efforts worldwide.
Insurers' hesitance stems in part from the experience of agencies in
Canada and other countries that have offered coverage and seen costs
and usage skyrocket. And many doctors who commonly prescribe pot
don't properly examine or follow their patients, said Cyd Courchesne,
chief medical officer at Veterans Affairs Canada, which has covered
medical cannabis since 2008.
"If I was working for any other company, and I was their medical
director, I would say do not reimburse," Courchesne said. "We do not
have enough information right now."
Cannabis research has been held back globally because most countries
ban its use, making purchases for studies illegal or difficult.
That's changing in Canada, where a booming marijuana industry and
the government now finance medical research, including efforts to
create cannabis-based pharmaceutical-like drugs.
Canada law allows patients to buy medical cannabis with money from
health-care spending accounts, which are financed by employers, but
insurance companies make their own decisions on coverage.
Some insurers are starting to cover pot in response to rising demand
from employees of the firms buying their coverage. Grocery chain
Loblaw last year became the first major Canadian company to ask its
insurers to cover medical marijuana.
But insurers are treading carefully. Sun Life covers pain associated
with cancer, multiple sclerosis, rheumatoid arthritis, HIV and
palliative care for serious illnesses; chemotherapy-induced nausea;
spasticity from MS; and anorexia due to HIV.
Green Shield Canada, Great-West Life and Manulife Financial Corp
have said they are considering or planning marijuana coverage.
Manulife, which offers marijuana coverage for a few companies that
requested it, recommends an annual reimbursement limit from C$1,500
to C$2,500 and covers only a handful of conditions, a spokesperson
said.
Great-West expects to begin offering medical cannabis coverage this
year, but only when confident it will both improve health outcomes
and hold down costs for employers. The firm is particularly
interested in covering marijuana when it might be more effective
than addictive pharmaceuticals such as opioids, said Brad Fedorchuk,
a senior vice-president.
Marijuana's often higher costs make it that much more important for
insurers to scrutinize the conditions they cover, said Mike
Sullivan, chief executive officer of insurance analytics firm Cubic
Health.
For instance, Baclofen, a muscle relaxer also used to treat
spasticity, costs C$28.82 for a ten-day supply. Health Canada has
estimated the average daily dose of marijuana, also used for
spasticity, at between 0.68 grams and 1.5 grams, with a gram costing
about C$8.
"If you open the door to conditions like post-traumatic stress
disorder, short-term sleep disturbances ... you start encompassing a
lot more people," Sullivan said.

SURGING COSTS
Veterans Affairs Canada began covering up to 10 grams per day of
medical cannabis for its members in 2008, with no limits on price or
medical condition.
After costs surged to C$63.7 million in the year ended March 2017
from C$19,088 in fiscal 2009, the group limited coverage to 3 grams
a day at C$8.50 a gram. Total reimbursements fell to C$51 million in
the year ended March 2018.
The agency imposed limits to give patients a more appropriate dose,
Courchesne said, but also considered costs.
Christine Gopner-Reinecke, a spokeswoman for Germany's AOK
Bundesverband - the largest of the groups administering the nation's
public health insurance - cited many of the same concerns on cost
and usage.
As of May, AOK had approved 9,700 patients for medical marijuana,
about two-thirds of its applications since Germany legalized medical
marijuana last March.
"We just cover it because the government wants us to,"
Gopner-Reinecke said. "We wouldn't cover it if it was up to us."
The Canadian Medical Association has warned its members to proceed
with caution, citing a lack of evidence supporting cannabis
treatment. Jeff Blackmer, the organization's vice president for
medical professionalism, said he authorized medical marijuana for
two of his patients when all other treatments had failed, but had
seen little improvement.
Research is also inconclusive on whether marijuana effectively
reduces pharmaceutical drug use when both are incorporated into
treatment, Courchesne said.
Some studies, including one conducted at the University of New
Mexico, have found that legal access to cannabis may reduce
pharmaceutical drug use in certain patient populations; but others,
including one published in the Journal of Addiction Medicine,
concluded that marijuana use increases the risk of prescription drug
abuse.
PRESCRIPTIONS AND FEES
Another problem, Courchesne said, are doctors and organizations that
prescribe marijuana with little scrutiny of patients' medical need,
often advertising themselves as a source of pot prescriptions.
Doctors' visits and prescriptions for any drug are generally free to
patients in Canada, covered by provincial governments. But groups
such as OneOunce.com and the Green Doctor Network directly charge
patients fees ranging from C$150 to C$295 for consultations leading
to marijuana prescriptions.
The Green Doctor Network requires no documentation or referral,
other than an online application form. The organization did not
respond to requests for comment.
OneOunce.com offers both in-person and Skype consultations, and
requires a diagnosis or referral from a family doctor or specialist
who has prescribed pharmaceutical drugs, said Fiona Fry, who handles
patient services. OneOunce charges fees, she said, because it uses
private physicians who don't bill governments and they spend more
than the usual 15 minutes with patients.
The Federation of Medical Regulatory Authorities of Canada expects
physicians to authorize marijuana only for patients with whom they
have an existing medical relationship and after in-person
consultations, Chief Executive Officer Fleur-Ange Lefebvre said in
statement.
National Access Cannabis contacts patients' doctors for their
medical history before writing pot prescriptions, said Evan Loster,
a senior manager. The service is needed, he said, because many
traditional doctors won't prescribe marijuana.
"Many physicians don't feel professionally comfortable recommending
a treatment they don't know enough about," he said.
