So I bought canna-oil that contains 1500 ml of THC. I want to use it in a brownie recipe and was wondering if I should use all of the oil I have, and then add normal oil to get to the required amount of oil in the recipe? Thanks.
1500 ml? That sounds like a tincture and not pure oil. From what I've researched online RSO is sold in California for $30-$80 per gram and 1 gram is about 1 ml so 30x1500= 45.000. So if you paid 45k it sounds about right.
If someone runs a dispensary and could correct my numbers please do but your stuff seems like its already greatly diluted. Also if your oil has already been decarbed, then exposing it to further heat in an oven could convert the THC and THCA to CBN.
