It's not uncommon for people to smell an illegal stench when they're out and about but it becomes worse when it's happening next door.
The smell of cannabis wafting over into people's properties isn't exactly the most welcome fragrance you can ask for.
It's a smell that's hard to miss and even harder to get rid of, but there are steps you can take to nip the problem in the bud.
Although some people think it is perfectly legal to smoke cannabis in their own home, it is still a Class B drug with possession punishable by up to five years in prison, an unlimited fine or both.
South Yorkshire Police said the force and its partners 'will continue to take action to improve the quality of life for communities who are affected'.
However, they have stressed that their best method of tackling the problem is by help from the public.
A South Yorkshire Police spokesperson said: "Local residents are often best placed to see on a daily basis whether their neighbours are behaving suspiciously and could be in possession of, cultivating or supplying drugs in their homes."
But, this doesn't mean that your neighbours will automatically know it was you that alerted police to problem.
Police have insisted that will never tell people information came from a neighbour and sometimes will use the tip-off as a starting point on areas they'll patrol.
As a result, they may smell cannabis themselves and knock on the door.
Crimestoppers have also said that people can contact them anonymously if they think their neighbours are smoking or cultivating cannabis near them.
A spokesperson said: "If you spot any of the signs that there may be a cannabis farm in your community you can call Crimestoppers anonymously on 0800 555 111 or use our Anonymous Online Form.
"You will not be asked any personal details and neither your telephone number nor IP address will not be traced or recorded."
However, if your neighbours rent their property, you can contact their landlord about this but are constraints as to what they can do.
A spokesperson for Nottinghamshire Police said: "If you own or let a property you need to be aware of your responsibility to ensure cannabis is not grown on your premises.
"Consequences of allowing cannabis cultivation include reduction in property values, increased insurance premiums, hostile tenants, and up to 14 years imprisonment and a criminal record."
If a landlord suspects the use of cannabis on their property, they can arrange a visit as long as they have warned their tenant they will be doing so.
However, landlords are not bound to keep your tip-off anonymous like the police will do.
