The same 100mg of CBD showed up eight-fold apart by product
Eighteen adults took 100mg of cannabidiol three ways. Peak urine levels reached 1,274 nanograms per millilitre from the prescription solution, 776 from a capsule and 151 from a syrup.
What the study found
At 100mg, the product mattered more than the milligrams
Eighteen adults took 100mg of cannabidiol three ways. Peak levels in urine reached 1,274 nanograms per millilitre from the prescription solution, 776 from a capsule and 151 from a syrup — eight-fold apart from one dose. A label's milligram figure says what went in, not what got through.
The caveat · Urine levels, not blood
Urine, not blood, so these concentrations cannot be set beside the plasma figures on the prescription label. About six people took each formulation, and each took a single dose in a residential unit rather than using the product over time.
