Whit? Open your eyes - who in the UK led with banning smoking, minimum pricing on alcohol, plain packaging on cigarettes, drinking in public (and at games)? These are existing, legal drugs which already bring in huge amounts in tax revenues and exports but they have been relentlessly attacked by Holyrood. Why on earth do you think the Scots are more likely to then decriminalise another drug? The English and specifically Londoners have a far more laissez-faire approach to cannabis and I certainly don't think it unlikely that some areas of London will have decriminalised cannabis sooner rather than later.
