An online therapy initiative to help people reduce or stop their use of cannabis is being launched today in Auckland.

PotHelp.org.nz - produced by the New Zealand Drug Foundation and funded by the Ministry of Health - is an online resource for people looking to address the impact their cannabis use has on them and the people around them.

Drug Foundation executive director Ross Bell said PotHelp featured compelling stories from people about the highs and lows of their cannabis use and their journey through treatment.

"The stories are from gutsy New Zealanders who stepped forward to share their experience, insight and hope on how they have successfully tackled dependency on cannabis or are somewhere near beginning that journey," Mr Bell said.

"People who are serious about cutting back or giving up cannabis will be able to work their way through the PotHelp online therapy with the support of these stories."

There was a 14-part work-plan that would help people change their relationship with cannabis for the better and gauge their progress, Mr Bell said.

"People are increasingly looking for help online, so this resource, the first online addiction therapy tool in New Zealand, helps people access support in the way they want it."

The service was private and confidential and no personal information needed to be given, he said.

"The Drug Foundation will never access records in a way that could reveal the identity of people who have registered, nor will we share or transfer personal information."
