CYCLONE Yasi has helped Far Northern police in the fight against drug use and growing, wiping out much of the region's marijuana crops.
The destructive wind which destroyed forest areas has exposed drug crops, the Cairns Post reports.
"We would expect that a lot of the cannabis would have been destroyed,” Far Northern Drug Squad Det Sen-Sgt Kevin Goan said.
"The surrounding foliage would no longer be providing cover and concealment to assist the cultivation of the plants."
Specialised lights used to grow marijuana plants are also believed to have been cut during the storm.
"If anyone were to be engaged in that activity long-term, a loss of power would impact on the success of their enterprise," Sen-Sgt Goan said.
