Our neighbours smoke cannabis for several hours a day, most days, but worse at the weekends when they smoke literally all day. They smoke it right outside their back door so it blows directly up the side of our house and the flat above them and seeps in through the windows but seems to get in even if the windows are closed. As a result our house stinks of cannabis,. Neighbours both side are pissed off as it's literally every day plus our next door neighbour in the flat above shares a garden with them and they let their dog crap all over the garden and don't clean it up for days. I've asked them twice before to stop smoking cannabis all the time and they said they would but didn't and completely sick of the stench, plus my 5 year old has had breathing trouble the last 2 weeks which we think could be linked to the smoke. Also to add that they have 2 kids of their own, a 5 year old and baby and I dread to think how much exposure they're getting. I want to call the police as I want it to stop but I hate being a snitch plus fear reprisals, as do our other neighbours who share the garden with them. AIBU?
