judge has ruled that a proposed ban on non-Dutch tourists smoking cannabis in coffee shops is not discriminatory against foreigners - so the ban will come into effect across the country by the end of the year.
Some coffee shop owners in Amsterdam are already warning that the ban will cost them up to 90% of their takings - and could force them to close their doors for good.
It means that the third of tourists visiting Amsterdam to smoke cannabis legally will almost certainly stay away - and tourist numbers visiting the city will fall dramatically. Other attractions, as well as bars, restaurants and hotels, will see reduced visitor numbers as a result.
It's not just the tourist industry that will be affected - the move will also mean that Dutch residents wishing to buy cannabis will be forced to buy their 'weed' from less regulated suppliers, leading to a likely upsurge in hard drug use.
That in turn is likely to lead to increased health and policing costs for everyone - and taxes will have to rise foot the bill.
These arguments have been hashed (sorry) about both in the law courts and, perhaps more importantly, the 'courts' of public opinion.
The mayor of Amsterdam Eberhard van der Laan is opposed to the law, which is the brainchild of the national Conservative-led Government. Some have even suggested it's part of a bigger political plot designed to bankrupt Amsterdam and force residents to vote Conservative to 'save the city'.
That seems a little far-fetched to me, but it does create a great opportunity for a tourist city like Brighton and Hove to replace Amsterdam as the liberal tourist's destination of choice: think of all the millions our shops and hotels would make if all those tourists being turned away from Amsterdam by the Dutch Tories came here to spend their holiday cash instead!
Of course, in Brighton and Hove, we know only too well the damage that the current drug policy of complete criminalisation of drug use is causing rather than seeing it as a health issue. Recently Caroline Lucas MP and the city’s top cop, Graham Bartlett called for decriminalisation of drug use and for good reasons. We frequently have the unwelcome title of the drug death capital of England with the highest drug death rate per capita of any city. Most of these deaths are from abuse of hard addictive drugs such as heroin. Interestingly, pioneering trials of giving heroin addicts injectable heroin rather than methadone are already taking place in Brighton and Hove: they are already reducing deaths and other negative health impacts from heroin use in the city.
Perhaps it's time to extend this sort of lateral thinking to the use of soft drugs too? Cannabis use can be harmful, but all analysis shows that it's much less likely to harm you than, say, driving a car, or crossing a road. The effects, like those from taking any drug, vary from personal to person - but most ill-effects are as a result of the tobacco it's usually consumed with.
NHS analysis has showed that there has never been single death caused by the ill-effects of smoking cannabis alone - compared to thousands on our roads.
While there are cases of less serious ill health caused by cannabis these are best dealt with, professionals say, by bringing the use of cannabis 'into the open'.
So what about it? Brighton, the liberal, tolerant, tourist capital of Europe?
I think these questions are worth asking - and urgently: for the sake of our tourist industry and the health and wellbeing of those living in and visiting our city. Nonetheless I expect to be misunderstood so I predict the following headline soon: Green Councilllor calls for Brighton to be the Pot Capital of Europe'.
