Come on America, legalise this shit already! We don't have a change in hell of getting weed legalised in the UK, even though it should be due to financial benefits alone!
Lead the way so the UK will follow.
Regardless of whether the US legalised it, that wouldn't change UK Conservative's perception and thus any legislation. If that were already a pattern we'd have medical marijuana here already, rather than a series of research papers loudly reporting the negative effects of smoking weed. There would need to be widespread political endorsement for legalisation to happen here and it will just never happen. Conservative MPs and voters would never go for it, they're too busy riding the war on drugs rhetoric.
