The CPS trial

The seven-month study involves daily and weekly online questionnaires on participants' smart devices. It also includes seven clinic visits to Tauranga Hospital in the Bay of Plenty. Participants will be required to have a urine test and wear a wristwatch-style sleep monitor for the duration of the study. Each of the 20 recruited participants will receive both a cannabis-based medication and a placebo in random order. 

A $40 supermarket voucher will be provided for each clinic visit.

• Be aged 25 years or above
• Be experiencing chronic back pain and sleep problems
• Be on a stable treatment regimen
• Be able to visit Tauranga Hospital for five clinic visits
