Older adults prefer CBD over THC composition. The table also shows the daily dose of cannabis oil according to composition used by the number and percentage of older adults. Although the precise dose of cannabis consumed by users was not available, most cannabis oil products in the marketplace containing almost exclusively CBD are formulated at 20 mg/mL. In the case of CBD and THC containing oils, the concentrations of active ingredients in available products vary, ranging from 20 to 50 mg/mL CBD in combination with < 1 mg/mL to 2 mg/mL THC
