How the Independent on Sunday got it horribly wrong on Cannabis

I knew that this was coming. A harm reduction group tackles the Independent on Sunday's reversal on pot.
They make the following points:

1. The facts are all over the place.
2. They fail to understand how drugs are used.
3. We haven't suddenly 'discovered' that cannabis is related to mental health problems.

Even if it's all true - what exactly is the IOS recommending?
Even if it's all true - what exactly is the IOS recommending? Ignore all other tedious witterings above for a moment and let's assume that cannabis really is 25 time stronger than 10 years ago and this really has led to a ten fold increase in teen cannabis addiction (whatever that might be). What does the IOS then recommend in its leader as a response to the policy disaster under which this skunk apocalypse has emerged?

Nothing: They say the the current policy is 'about right'.

Do we get an exploration of policy alternatives or a consideration of progressive policy in other European countries where the problems are markedly smaller? No. Instead we are told that the 'the fact possession of cannabis - and other drugs - is illegal acts as a important social deterrent'.
