As ever with you, a shallow and uninformed take based on rather mediocre experience.
The ACMD (look it up) recommended that Cannabis NOT be returned to Class B, but were ignored by the ministers in 2009. In 2012 the Home Affairs Select Committee reported on UK drugs laws. They were split over down classifying Cannabis back to C, with 3 Vs 3. Thus the status quo was maintained.
This should be enough to tell you that the situation is far more nuanced than you make out. If your contact with the police had been something more than at pedestrian level you would know that police chiefs favour decriminalisation of hard drugs, with National Police Chiefs’ Council and College of Policing choosing to effectively decriminalise first time offences of cannabis and cocaine use. The only thing preventing them from being more outspoken are political constraints, especially now that we have a hard right government looking to appeal to gammon like you.
There are almost no people involved in drug treatment or enforcement who view punitive approaches as effective. Added to which, there are plenty of harm reduction models in action in Portugal, Netherlands and even the US.
That almost half of US states have legalised cannabis should be evidence enough of how far behind the UK sits.
