A large group of Halifax, N.S. landlords is voicing their concern about the prospect of renters growing and smoking marijuana in their units when the federal government鈥檚 plan to legalize marijuana comes to fruition.

The Investment Property Owners of Nova Scotia (IPOANS), whose members own nearly half of the apartments in Halifax, told CTV Atlantic that they鈥檙e especially worried about tenants growing pot in their properties.

鈥淚t is the biggest issue we鈥檝e faced,鈥 Jeremy Jackson, president of IPOANS, said. 鈥淭he normal apartment is not geared, electrically, ventilation-wise, they鈥檙e not geared for that sort of grow op.鈥

Advocates for marijuana legalization, however, say using air filtration systems can address landlords鈥 concerns and destroy any pot odour.

Chris Enns, a supporter for pot legalization, compared the issue to any other dispute that might pop up between neighbours in an apartment building.

鈥淭he individual who lets his dog bark all day, people who use really potent spices that might be nauseating for one, but sensually pleasurable for another,鈥 Enns listed.
