Second-hand smoke a top concern in B.C. cannabis consultations

Second-hand smoke has emerged as a top concern as the province nears the end of public consultation on cannabis regulation, says B.C. Public Safety Minister Mike Farnworth.

The province is working to draw up rules for the sale and consumptionof non-medical cannabis before it is legalized by the federal governmentin July,2018. B.C.'spublic consultation period endsNov. 1.

It will take time for the ministry to sortthrough the more than 30,000 responses it has received so far, Farnworth said.

But it's already clear thatmany people are worried about second-handmarijuana smoke, he added.

'Strong views'

"People have very strong views, particularly when it impacts their private space, such as their condo unit for example or their backyard or whatever," he said.

The issue will be addressed inthe new cannabis regulations, Farnworth said.

"It's one that was fully anticipated as an issue, so I expect, in fact I know, it will be dealt with in the new regulatory framework."

Some hope the new rules will go further than what is in place to protect people from second-hand tobacco smoke.

Legislation in 2008 ended smoking in the common areas of apartment and condo buildings, but the rule doesn't apply inside private suites.

Call for more protection

The Clean Air Coalition of B.C. regularlyreceives complaints from people in apartments and condos about both marijuana and tobacco smoke, said director Jack Boomer.

Peoplecan complain to the Residential Tenancy Branch ifsmoke from a neighbouring suite is ruining what is known as the "quiet enjoyment" of a unit, butBoomer said the results of complaints vary.

"One of the things that we would encourage the provincial government [to do] is actually amendthe residential tenancy laws so they actually reflect the fact that quiet enjoyment includes tobacco smokeand cannabis smoke," Boomer said.

Another possible solution is to requiredisclosure of which suites in a building do not have no-smoking clauses in their tenancy agreement, Boomer added.

That way people can decidewhether second-hand smoke may be an issue before moving in, he said.

More research needed

Because cannabis has been illegal in Canada, little research has been done on the potentialharms of exposure to second-hand marijuana smoke, said Dr.Milan Khara, an addiction physician with the smoking cessation program at Vancouver Coastal Health.

But it's reasonable to expect the effects are similar to tobacco smoke, Kharaadded.

"Very likely marijuana smoke is as harmful as cigarette smoke, but the evidence at this time is not well established."

However, Dr. Ian Mitchell, a cannabis prescriber in Kamloops whois studying the effectiveness of medical cannabis onPTSD symptoms, disagrees.

Mitchell says while second-hand cannabis smoke has not been the subject of much research,studies have shown direct cannabis smoke does not have the same detrimental affects as tobacco smoke.

"You might not like the smell, but it's really not a danger to anybody."
