Study type
Interventional
Description of intervention(s) / exposure
Participants will be offered a 50mL bottle of LGP Classic CBD 50, LGP Classic 1:100 or LGP Classic 1:20 according to doctor/patient preference and product availability.

LGP Classic CBD 50 (THC/CBD 0.2mg/50mg per mL) oral solution (dose range 0.05mg/12.5mg - 0.4mg/100mg) per day. Dosing commences at 0.25ml daily increasing every 3 days for the first 14 days; reaching a max dose of 1ml twice a day. Between days 0 and 11 the dose will increase by 0.25mls every 3 days. Day 12 to 15 the dose will increase by 0.5mls every 3 days. The day 14 dose is then continued for day 15 - 27. If the participant experienced adverse effects the dose can be reduced to the previously tolerated dose. If the dose is effective prior to day 14, continued titration is not required.
Participants are required to bring the study drug to each study visit for monitoring and compliance of mls (volume) remaining in the bottle.

LGP Classic 1:100 (THC/CBD 1.5mg/100mg per mL) oral solution (dose range 0.375mg/25mg - 3mg/200mg) per day. Dosing commences at 0.25ml daily increasing every 3 days for the first 14 days; reaching a max dose of 1ml twice a day. Between days 0 and 11 the dose will increase by 0.25mls every 3 days. Day 12 to 15 the dose will increase by 0.5mls every 3 days. The day 14 dose is then continued for day 15 - 27. If the participant experienced adverse effects the dose can be reduced to the previously tolerated dose. If the dose is effective prior to day 14, continued titration is not required.
Participants are required to bring the study drug to each study visit for monitoring and compliance of mls (volume) remaining in the bottle.

LGP Classic CBD 1:20 (THC/CBD 1mg/20mg per mL) oral solution (dose range 0.25mg/5mg - 2mg/40mg) per day. Dosing commences at 0.25ml daily increasing every 3 days for the first 14 days; reaching a max dose of 1ml twice a day. Between days 0 and 11 the dose will increase by 0.25mls every 3 days. Day 12 to 15 the dose will increase by 0.5mls every 3 days. The day 14 dose is then continued for day 15 - 27. If the participant experienced adverse effects the dose can be reduced to the previously tolerated dose. If the dose is effective prior to day 14, continued titration is not required.
