KINGSTON, Jamaica - A 71-year-old Canadian woman caught with 3.6 kilograms of marijuana in her luggage at a Jamaican airport has been jailed for drug-smuggling.

Margueritta Lancaster-Reid will remain in jail for three months, unless she pays a $1,200 fine.

The woman dubbed "ganja granny" by local media was sentenced Friday by a court in Montego Bay.

She pleaded guilty to drug charges earlier in the week.

Police stopped Lancaster-Reid at Donald Sangster International Airport on March 28.

The Jamaica Observer newspaper says she told officers she was carrying "herbs" when the drug stash was found.

Police did not give a hometown for Lancaster-Reid, saying only that she is from Ontario.
