The ministry's submission to Parliament's health select committee says most New Zealanders who used cannabis used it only occasionally, and reported few health problems. "Overall, the current public health risks of cannabis use are small to moderate in size, and are less than the public health risk of tobacco or alcohol use," the ministry's submission says. Studies had failed to demonstrate any evidence that even acute cannabis use caused brain damage, and suggested that even long-term heavy cannabis use caused only subtle impairment of cognition, the submission says. High doses could produce short-term psychosis, and could exacerbate schizophrenia in those already affected by the condition, and about 10 per cent of users were dependent on cannabis, the ministry said. "Beyond that it is difficult to draw any sort of definitive cause-and-effect relationship between cannabis and mental illness." Deputy director of mental health Nick Judson said no more than 2 to 3 per cent of the population were at serious risk from cannabis. The ministry also acknowledged that in many parts of New Zealand mental health and drug and alcohol services had not been well coordinated, so failed to meet the needs of many with mental health and substance abuse problems. Drug Policy Forum Trust director David Hadorn said that research had largely exonerated cannabis as a cause of mental illness. The mental health of New Zealanders was put at greater risk by criminalisation of cannabis than cannabis itself, he said. "Creating a climate of criminality around cannabis ensures that the relatively few people who develop problems are less likely to seek help. This sets off a spiral of alienation, marginalisation and anti-social behaviour, which too often can culminate in criminality, mental illness and violence." "By driving cannabis use underground, we surely make the situation far worse than would be the case under a controlled, regulated system of cannabis distribution. Creating a flourishing black market for a widely used substance inevitably fosters criminal activity." Dr Hadorn said the only drug proven to contribute to violence was alcohol, and cannabis had the opposite effect. "It tends to encourage people to stay home and watch Cheech and Chong movies and listen to Pink Floyd." "Honest" education programmes were needed to reduce cannabis use by young people, but the "hyperbole approach" used by New Zealand police just encouraged young people to experiment, Dr Hadorn said. Assistant police commissioner Ian Holyoake said police opposed legalisation of cannabis, but were "not blind to the issues raised by the legalisation lobby". But till there were better programmes to reduce the harm caused by cannabis, its illegal status "remained a powerful tool", Mr Holyoake said. "Police take the view that cannabis is an inherently harmful drug with serious health risk to regular and long-term users, especially the young," he said. Mr Holyoake admitted police had had limited success in reducing cannabis offending, and had failed to halt involvement of gangs in cannabis cultivation and distribution. He said cannabis had a huge impact on Maori communities, especially in Northland, Bay of Plenty and Poverty Bay. "Police working in these communities speak of a dead generation or two, and of young people losing touch with their elders and their families. Their focus in life is cannabis -- growing, smoking and the culture -- rendering them blind to life's opportunities. - --- Checked-by: Mike Gogulski
