Police hope educating the public about the smell of cannabis will make it easier to clampdown on those growing the drug.
Hundreds of police officers have failed new fitness tests which are due to become mandatory later this year, official figures show.
In a damning report, the HMIC said police are failing victims of domestic violence right across England and Wales. Urgent reform is needed.
Hundreds of police officers are still failing new fitness tests which are due to become compulsory in weeks, official figures show.
Some 352 officers fell short with 2% failing overall in more than 13,000 tests across 32 forces, latest results from the professional standards body the College of Policing said.
After taking part in the 15-metre "bleep" shuttle run test, some 138 of the 10,265 male officers who took part, an average of 1%, and 214 of 3,693 female officers, an average of 6%, were unsuccessful.
The new fitness testing, which will become compulsory on September 1, was brought in after recommendations made by Chief Inspector of Constabulary Tom Winsor.
If an officer fails the fitness test at the first attempt, it is advised that at least two retakes are permitted before forces use "unsatisfactory performance" against the participating officer.
No charges will be brought against police officers over the death of father-of-three Habib Ullah who died after being searched for drugs in 2008, his family's solicitor said.
A shotgun disguised as a walking cane has been handed into Greater Manchester Police as part of a firearms amnesty.
The cane is estimated to have been made in the late 1800s and has a shotgun concealed in the casing. The weapon was often carried during the 19th and early 20th century by men hunting wild game on their grounds.
Assistant Chief Constable Ian Wiggett, pictured with the cane gun, said: “This cane gun is a very peculiar discovery.
"As a prohibited weapon, not even a license will cover the possession of this item, so the owner did the right thing in handing it over to us, where it will be processed and safely destroyed.”
The shotgun was handed into police as part of the ‘Give Up The Gun’ amnesty which is due to finish at 11.59pm on Saturday 26 July. So far, 164 weapons and hundreds of rounds of ammunition have been handed over to police.
Police forces could be placed in jeopardy in three to five years' times due to slashed budgets, watchdog Her Majesty's Inspectorate of Constabulary (HMIC) has found.

Continuing to apply the cost reductions in the same way in the next four years as they've been applied in these four years is not an option, and we're very clear that the viability of some forces could be placed in jeopardy in three to five years' time.
By that we mean they would have to cut too hard and too deep into neighbourhood policing and they may not be able to guarantee or maintain the service that we're currently seeing to the public.
A police watchdog has raised "growing concerns" that local bobbies are being taken off the beat, as it warned some forces may struggle to cope with major crimes such as rioting or multiple murders in the next few years.
Her Majesty's Inspectorate of Constabulary (HMIC) found that neighbourhood teams are being stretched with extra work that keeps them in the office, and revealed a third of people had seen fewer police officers on patrol in the past year.
The watchdog also warned that the future of some smaller forces could be at risk in the next three to five years if recent methods used to slash budgets do not change.
Those with low police officer numbers and a low cost of policing per head were highlighted as being the most vulnerable, with Lincolnshire and Suffolk among forces deemed to be at risk.
A 73-year-old woman has died in hospital after being bitten by a police dog that was searching for a suspect in her garden.
Irene Collins was attacked by the German shepherd last week at her home in Middlesbrough.
The Assistant Chief Constable of Cleveland Police, Sean White, said: "Members of Cleveland Police share the grief that is felt and we all wish to express our sincerest condolences to the family."
Mr White said the Independent Police Complaints Commission had been informed of the incident and would be deciding how to investigate what happened.
He said the force were "commited to learning any lessons" from the incident, but stressed that using dogs was "operationally important" to fighting crime and protecting the public.
The dog involved has been withdrawn from duty, while its handler is also receiving support, he added.
A code of ethics for police forces across the country will give the public "even greater confidence" in officers, a member of an influential committee has said.
Conservative James Clappison, who sits on the Home Affairs select committee, told the Daily Telegraph:
– James Clappison
The over-whelming majority of the police are polite to the public but I think it is useful to set out.
I think this will be good for the police themselves and for the public and give them even greater confidence in them. The overwhelmingly majority of police are decent and conscientious.
If officers breach the code of ethics a range of sanctions are available. Officers may simply be given a verbal warning or moved to another team, but more significant failures will require formal investigation and may result in an individual losing their job.
Police officers who are rude in public or work while unfit face being punished under a new code of ethics drawn up to improve the force's reputation.
The guidelines, written by The College of Policing, would punish officers who appeared for work under the influence of alcohol, and those who had sex or took drugs while on duty.
Officers will be urged to blow the whistle on colleagues of all ranks and failure to comply to regulations could lead to disciplinary action and even dismissal.
The College of Policing hope the guidelines will help to restore the public's faith in the police, after a series of corruption, race and behaviour while undercover scandals rocked constabularies across the UK.
The Home Secretary is understood to back the guidelines and they will go before parliament, although no date has yet been finalised.
Police officers face being punished for being rude to the public under new rules planned to improve the reputation of service.
Warnings about clocking on when unfit or impaired through drinking alcohol, using drugs or having sex while on duty will also be contained in the new code of ethics.
Officers will be urged to blow the whistle on colleagues of all ranks if they breach professional standards.
Failure to abide by the rules could result in disciplinary action or even the sack.
