A brochure instructing teenagers on how best to smoke crystal meth has unsurprisingly ruffled a few feathers.

Students at west Auckland's Massey High School were issued with an educational pamphlet outlining 10 ways to 'keep well' while using the Class A drug - courtesy of the DrugHelp programme.

The literature advised readers to always use a new needle when injecting, avoid smoking after 3pm if they 'want to sleep later' and beware of glass pipes that can 'get damn hot', Stuff.co.nz reports

A brochure instructing teenagers on how best to smoke crystal meth has ruffled feathers among parents

The pamphlet outlines 10 ways to 'keep well' while using the Class A drug, including cleaning the inside of the pipe regularly, always using a new needle and being discrete by keeping less than five grams for personal use

Massey High School, in west Auckland, has come under fire for circulating the drug education booklet

'If a student was curious about using methamphetamine, the pamphlet told them how to use it,' said local mother Morgan Julian.

Ms Julian's daughter was handed the brochure during a Year 13 health class.

'It reads through, very clearly, on ways to do meth and how to hide meth.'

'I am all for drug education and keeping our children aware but to blatantly publish a step-by-step guide on how to clean your pipes, swallow instead of injecting and to do it legally, in a way is disturbing.'

Morgan Julian, whose daughter was handed the brochure in during a Year 13 health class, has voiced her outrage - saying that 'If a student was curious about using methamphetamine, the pamphlet told them how to use it'

At one point the pamphlet goes so far as to suggest that users 'Be discrete and only keep less than 5 grams for personal use', since 'Meth is illegal.'

Another advises users to 'eat something every 4 or 5 hours... if you've been awake longer than 24 hours, have a break' and 'if using a glass pipe, clean the inside regularly.'

Despite stoking outrage among some parents, however, the school's use of the pamphlet has been strongly endorsed by the Drug Foundation.

'I applaud Massey High School for using it in the context that they used it in,' said Drug Foundation executive director Ross Bell.

'People would be living under a rock if they didn't think there was a meth problem in New Zealand.'

Massey High School insists that the brochure is a valuable educational resource 'which aims to provide context for students around an issue which negatively impacts far too many young people in New Zealand'

The school's use of the pamphlet has also been strongly endorsed by the Drug Foundation, who said that 'People would be living under a rock if they didn't think there was a meth problem in New Zealand'

Massey High School insists that the brochure, which is more typically distributed in prisons, is a valuable educational resource.

'It is one resource which aims to provide context for students around an issue which negatively impacts far too many young people in New Zealand,' the school said in a statement.
