Although I have no time for the crap, its about time we decriminalised dope in NZ.
I was born and raised in a country where it's legal (Netherlands) and can't say I favour that approach.
By legalising it you're making it very easily accessible especially for young adults and the amount of abuse is just as high as in any other country where it's illegal.
Because it's legal you lose the challenge to do "something naughty" as a kid, however by making it as easy as a buying a pack of gum it doesn't seem like a big deal either.
The problem with it is that consumption peaks with kids & young adults (aged 15 to 25), of which the under 18's get adults to buy the stuff for them.
These are the ages where your brain develops and the result of legal weed has shown a large increase of people that
- revolt against society (don't like the system, don't want to be part of it)
- feel no need to work or contribute (increase of self-importance and loss of focus on achieving education and finding work)
Not to mention the negative impacts on brain development and general health overall.
Sure this does not apply to everybody, (there are many strong minded and intelligent adults that can regulate their consumption to appropriate levels), but making it fully legal makes it so much easier for those with lesser willpower to fall victim to it and sidetrack their chances of building a successful life.
My solution would be to strictly distribute the stuff in limited quantities for leisure consumption and for medical purposes, rationed just like you get a prescription from the pharmacists.
This breaks the cycle of the illegal distribution as the state controls the quality and pricing of the product (putting the illegal network out of play) and protects the vulnerable from addiction by only supplying what they need. There might be a risk that certain people will share their allocated lot but it's still better than giving it free completely. Also, those that apply to receive their "medication" should be properly tested for psychological history as there is evidence this could have a negative impact.
So far my preaching :P
