An oldie but definitely a goodie. This argument by Theodore Dalrymple* provides a cogent philosophical and legal case against legalising illicit drugs.
A newie but also a goodie. Despite the psychological (psychosis, addiction) and physical damage (lungs and lung cancer) cannabis is known to cause a rearguard group of drug industry leeches are setting to prevent its upgrading to a Class B drug in Britain. They will lose as they should.
Australia should strengthen not weaken its laws against cannabis use by continuing to prosecute users in the courts as well as suppliers.
* Dalrymple has appealling views on the myth that individuals cannot overcome the difficulties of addiction. I also appreciate his objectively accurate views of heroin users - these are not an 'alienated' group of sad individuals unable to adjust to an unfair society. In the main they are low IQ, dishonest losers who deserve no adulation. I like Dalrymple's attempts to de-mythologise.
