Denny and I were making cannabis oil tincture the other day, and suddenly we were like, DUH – we haven’t done a post about this yet! We’re all about making our choice to use medical marijuana as affordable as possible; buying Full Extract Cannabis Oil (FECO) to make your own tincture is a great way for tincture users to cut costs.
We’ve done posts about making your own FECO if you grow your own, but you can buy FECO if you don’t have the flower/trim to make your own. Many caregivers sell FECO, and if yours doesn’t, chances are she or he can refer you to someone who does. In our case, we have FECO, but we haven’t had it tested yet, and we needed tincture we could use in specific dosing amounts in a hurry. Test results can take at least a couple weeks.
So we went to Highbrow to grab a gram of FECO. The budtender at Highbrow shared the test results with us, telling us the THC content was 62%.
Hats off to Highbrow, by the way, for using glass syringes for their FECO. They’re easier to use than the more common plastic ones, and it just seems like glass is a more appropriate vessel for an oil known to break things down. We love reusing their glass joint vials to cure our home rolls, too. Who knew curing joints in glass could improve them so much?
Besides the FECO, all you need to make a basic tincture is a carrier oil. We use an organic coconut one. One gram of FECO with a THC content of 62% means that gram contains 620 mg of THC. Doses of tincture are often measured in milliliters (ml), and we were shooting for roughly 10 mg per ml. This gram would produce roughly 62 doses at 10 mg per ml.
There are 29.57 milliliters in an ounce. We round this number up to 30 to do the math, which means two ounces of the carrier oil (62 divided by thirty) were needed to reach our goal dose.
First, you need a pan of water heated on the stove. We usually bring the water to boiling, then remove it from the stove to cool down a few minutes before using it as a sort-of double boiler.
Place the measured amount of carrier oil into a bowl that is appropriate to use as the inner layer of a double boiler. Squeeze the FECO into the carrier oil. You may need to hold the closed syringe in hot water to soften the FECO enough to manipulate the syringe. Place the bowl with the carrier oil and the FECO into the pan of water and stir with a whisk or a fork until the FECO has dissolved evenly into the carrier oil.
Then pour your tincture into whatever vessel you’ll be storing/using it from. Glass tincture bottles are available online and at a variety of brick and mortar stores. Canning jars work well, too, except the glass is clear so you should probably store them in the dark. Milliliter measures can be bought online or at local drugstores, too.
The gram of FECO costs $25 at Highbrow and made two ounces of 10 mg per ml tincture. Organic carrier oils can be expensive, but the larger the container, the cheaper the per ounce price.
