I personally have never smoked cannabis and I imagine I probably never will; but I believe steadfastly that I have no right to impose my own values and my own opinions regarding drug use upon others.
This is a view which, when I discuss it with many of my peers at school, is often shared. By all accounts, cannabis is not a very addictive drug, far less so than tobacco, and individuals are well aware of the harms it causes to their bodies. But there are also benefits to enjoy with the use of these drugs, just as some people enjoy smoking cigarettes or drinking alcohol.
It is not for me to decide for others whether the benefits or the costs of marijuana use are greater, because that is an entirely subjective decision to make. From a standpoint of individual liberty, it seems to make sense to legalise marijuana.
But even if we conceded that the use of cannabis had universally negative outcomes, the criminalisation of the substance does little or nothing to reduce its use and only exacerbates its harms.
This year's United Nations World Drug Report was what piqued my interest and spurred me to write a column on the issue. It identified Australia and New Zealand as having some of the highest rates of marijuana use in the world.
Estimated annual worldwide usage of cannabis is between 2.5 and 5 per cent, while the report stated it is between 9.1 and 14.6 per cent in New Zealand. That's higher than in countries where the use of cannabis is decriminalised, such as the Netherlands and Ecuador.
Arguing that cannabis is a gateway drug and legalising it will heighten that role ignores the fact that criminalisation does little to reduce its use.
Attempts to enforce these laws, which costs the Government around $100 million a year, are largely futile.
The more pertinent issue is what happens as a by-product of this ineffective criminalisation. Maintaining the illegal status of marijuana does not make it disappear, but the individuals or organisations who now produce and supply it are always going to be those willing to break the law and risk the consequences of getting caught doing so.
Obviously, these people and groups are, for the most part, gang members, who have little interest in ensuring the safety of what they are selling. If you can't pay for your drugs on time, you get beaten up and physically forced to pay it.
By contrast, in the world of legalisation, there are regulations ensuring safe and not pernicious substances are in the cannabis, there is a greater willingness from those who do get addicted to seek help as they are no longer branded the law-breaking scum of society, and the consequences of any issues you have with the supplier are just like any other product where recourse is sought through the hand of the law rather than the fist of the gang member.
Cannabis itself seldom causes fathomless and incomprehensible harm to the user, but the war on cannabis does exactly that.
More of the leaders of our world are starting to consider the indisputable futility of current anti-cannabis laws and the indefensible and pervasive effect they have on freely acting users. This is comforting, and the increasing support for decriminalisation from younger generations means that political barriers will be unlikely to stand in the way of such an principally proper and practically sensible law change for much longer.
