How can people best be supported to become

smokefree?

The ABC Approach

•A - ask whether a person smokes

•B - give brief advice to quit to all people who smoke

•C – make an offer of, and provide or refer for cessation support

How does the ABC work?

• Aims to provide better help for smokers to quit.• Can be easily integrated into everyday practice,

so that smokers are presented with every opportunity to quit.

• Can be personalised.• Emphasises being encouraging and providing

people the support and tools they need to become smokefree.

“A little and often by many over time works.” (Fiore 2000)

A- Ask

• Ask whether a person smokes & document in notes

• Ask routinely &• At least every six months

“Are you currently smoking?”

“Last time we caught up you were smoking, how are you doing with that?”

B- Brief Advice

• Personalise your advice

• Acknowledge that it’s difficult

• Be supportive

PHARMACOLOGICAL

•Nicotine replacement therapy (NRT) patches/gum/lozenges subsidised•Other medications available on prescription (Zyban, Nortriptyline subsidised & Champix subsidised for eligible people)

BEHAVIOURAL

•Telephone/Txt-based support - Quitline - SmokeStop•Face-to-face support - Asian Smokefree - Aukati KaiPaipa - Pacific Quit Service - Pasifika Smoking Cessation - Pregnancy Services - Specialist Hospital Services - Local Quit Smoking Coaches

Combining both gives the greatest chance of success

C – Cessation (Quit) support

What is NRT?

• NRT safely replaces some of the nicotine that is normally provided by tobacco, and reduces the severity of withdrawal symptoms.

• NRT roughly doubles the likelihood of a successful quit attempt.

• There are a range of products available, and different products will suit different people.

• Not a magic cure – effort, support and strategies are also needed.

• Only $3 for 8 weeks supply

Quitting without supportThe majority of people who quit this way will relapse in the first week

Only 2.5%

abstinent at 1-year
