We moved into our house 4 years ago and without wishing to sound snobbish our neighbours are a bit rough.
Nevertheless they are fairly pleasant and we get on well with them.
When we moved in the wife warned us that there was a cannabis problem in the neighbourhood.
Now the smell of weed in my daughter's bedroom is really bad and it is obvious that it is coming from next door, probably from the husband.
How can we tactfully deal with the issue without falling out with them.
We know who their landlord is but we don't want to go down that avenue if we can avoid it.
