My last blood test showed my bilirubin was slightly high at 2.0.i have been using cbd,cbn with thc in it for pain and sleeping . i am almost 80 could this have anything to do with the increased level?

High bilirubin (hyperbilurinemia) alone isn't a known side effect of CBD & related products. It is not rare to have mild hyperbilirubinemia sometimes when a comprehensive panel is done even it has been normal in the past. However, early biliary obstruction can give you that number but the other liver enzymes are still normal. Retesting total and direct bilirubin would be appropriate at your age.
