Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
There are 3 treatment arms:

Group 1: Remotiv (250mg Ze117; standardised to 500mcg Hypericin).
Group 2: Nicabate CQ (Committed Quitters) Clear (Registered TradeMark)
Group 3: Remotiv (250mg Ze117; standardised to 500mcg Hypericin) and Nicabate CQ Clear (Registered TradeMark) combination

The Remotiv (Registered TradeMark) group will undertake a 4 week wash-in treatment period prior to the quit date in order to achieve therapeutic benefits from the herb. Remotiv will be administered orally. Dosage - 1 tablet 2 times a day for the first 12 weeks and then 1 tablet per day for 2 weeks (week 13 and 14).

Group 2: Nicabate CQ clear (Registered TradeMark) - individuals in this group will be asked to commence treatment on their quit date. NicabateCQ is an over the counter pharmacy medicine and treatment consists of a 10 week step down process consisting of a single transdermal patch delivery of the following doses of nicotine over a 24 hour period:

Step 1: 21mg nicotine per day for 6 weeks (weeks 1-6)
Step 2: 14mg of nicotine per day for 2 weeks (weeks 7&8)
Step 3: 7mg of nicotine per day for 2 weeks (weeks 9&10).

The nicotine patch is applied in the morning after a smoke free night to a clean, non-hairy site anywhere on the upper body or arm.

Group 3: Remotiv/Nicabate CQ(Registered TradeMark) combination – Participants will begin taking the Remotiv treatment 4 weeks before their quit date (as per group 1). On the quit date (4 weeks after the Remotiv wash-in period), participants will commence treatment with nicotine patches (as per group 2) and will continue taking the Remotiv treatment for another 10 weeks.

4 weeks pre-quit, quit date, 6 and 10 weeks post quit
Secondary outcome [1] 7756 0
Patterns of brain activity will be measured using a technique called Steady State Topography (SST). This brain imaging technique is a non-invasive computerised tool. Small recording discs are placed on the scalp to measure brain function. A small quantity of a water-based conductive gel will be used to make electrical contact between the scalp surface and the recording discs. This will be washed-off once data collection has been completed. The application of recording discs does not involve any breaking or piercing of the skin. A pattern on a computer monitor will change while the participant concentrates on the centre of the pattern.
