OK, I'll bite as I can see HAs and "enforcement" mentioned a few times..
I'm an ASB officer for a VERY large HA. We cover the whole of England.
I've worked this role for oooh, 20 years, give or take.
Cannabis smoking is our 3rd biggest report type, after verbal abuse and noise.
You know how many people I have evicted just for smoking cannabis......0.
Why?
Because HAs cannot evict their own residents, only a court can do that. That person could break every single section of their tenancy agreement, pay £0 rent and still unless a Judge agrees that person keeps their home. (There are mandatory possession grounds here, but cannabis smoking wouldn't apply)
I have secured evictions when that person is doing other ASB which is evidenced, but how do you evidence a smell? We rely on police finding the drugs, testing the drugs and convicting them in court for possession.
I did think I had a slam dunk case once. Up North in Derby, block of 6 flats. 1 prolific cannabis smoker. Perfectly polite resident but smoked like a chimney. 5 complainants, detailed diaries from each of dates/times they smoked it. Police issued CPWs (never found actual drugs but could smell it). 6 months of reports, cannabis smoker never, ever engaged with me..
So, I thought fuck it. Completed a proportionality assessment and served a NOSP. Breached NOSP so sent to court. 4 residents attended to give evidence, perp turned up, said he smokes it to "relax".
Judge turned to me and said "MrsMoose are you seriously suggesting I should make this person homeless, and unable to access ongoing housing purely because he is creating a bad smell"
"No Judge, I am asking for possession of the property because he is in breach of his tenancy, smoking an illegal substance and having a detrimental effect on his neighbours ability to enjoy their homes"
Judge responds "MrsMoose, I do not agree that a smell is enough to warrant making someone homeless. If the witnesses here don't like the smell, tell them to open their windows. Case dismissed. Costs to be paid by the Claimant"
So, we lost AND had to pay the dope heads legal fees.
Of course, very few Judges live in an area where prolific cannabis smoking is likely to be an issue..
But now, my HA will not enforce cannabis smoking unless it's linked to other ASB..
What we're seeing much more of now is young teenagers, mostly male, around 12-16yo getting involved with gangs and smoking cannabis. Their behaviour is vile, social services try to intervene but the family and teen doesn't engage properly and eventually it escalates until that teen does something serious. One particular case springs to mind where the boy stabbed a rival on a bus.
For HAs it's not just "sue" or "enforce". The legal system in this country is complex and HAs are required now under govt legislation to always be working to MAINTAIN tenancies, not applying for evictions.. it has to be some serious ASB to consider evictions and smoking cannabis is not that.
Believe me, it annoys me having to tell complainants this and directing them to the police reporting websites instead (knowing police won't do anything) but other than sending a letter saying we've had a report your smoking cannabis, please stop, there is little else a HA can do as the power lies with an outdated court system.
