Since we are talking about marijuana in particular here, I feel that it's necessarily to point out that marijuana is a very relaxing drug and one is substantially less likely to intentionally harm others while on it.
Whilst I can see an argument for the legalisation of certain drugs I consider others to carry too high a risk of collateral damage. I believe in small government but living in the UK I believe there is a certain duty to try and live reasonably well, national health service and all.
Cannabis is an odd one. In theory it's harmless but in practice the UK saw a huge upsurge in usage when it was reduced to class C, this wouldn't have been a problem but we also started to see increasingly strong evidence of cannabis being linked to mental illness. Another factor that became increasingly clear was that the 'gentle stoner' stereotype was as much a product of the old cannabis culture as it was of the drug itself, as the number of users grew their connection with the 'stoner' ideal disappeared and plenty of violent crimes were committed while high. Basically the English brought our traditional slightly Nordic approach to drinking (a lot at once) to cannabis use and people were simply not doing what you'd expect stoners to do.
Personally I don't think it should be legalised yet, I reckon it will be eventually but we need to do some feasibility studies first; police costs, medical burden, taxation etc.
Also, from a personal observation, we could probably stand to go back to weaker strains.
