Smoking P can make you feel euphoric but it destroys the lives of users and is very addictive, Anti-P Ministry founder Brendon Warne says.
The effects could be seen in domestic violence, shoplifting, burglary and grandparents bringing up grandchildren.
The ministry, which aims to help people who want to stop using the drug, is raising awareness in Whanganui's Majestic Square on Saturday, March 13. Warne plans to drive the ministry's bus down Victoria Ave just after 11am.
Whanganui contact Shanette Hirst sets up outside The Warehouse every Wednesday from noon to 2pm, ready for people to approach her.
The Anti-P Ministry is a registered charitable trust. Its members are former P users who understand what addicts are going through.
