Weed problem from a nextdoor neighbor

[Niti Bhat]

We have a townhome in Raleigh which has been rented to a nice couple. They are facing issues with their next door neighbor who uses weed and the smell of it is coming in their home too from the vents, which is causing them lot of difficulty, breathing problem etc. We reported this to HOA but they are not doing anything. The couple don't want to talk to the neighbor directly as they are scared.

Has anyone faced similar situation? Should we report it to the cops?
