Thread: How to make Concentrated Cannabis Oil

    Default How to make Concentrated Cannabis Oil

    Please be aware that making CO/RSO can be very dangerous if you are not careful. The solvent used for extraction in highly flammable. Please take extra care!
    Also, treat this medicine with respect. This is seriously potent and if not dosed correctly, it will put you flat on your back. Ingesting this half the size of a grain of rice will knock you sideways and the high is intense!! You’ve been warned! lol


    Before you start, it's good practise for a 4 week cure. Do not decarb your buds straight from the jar. You need to dry them out more. Set your oven to it's lowest temp. Mine is between 80 & 90 C. 15-20 mins at that temp should be enough to dry them. They will feel crumbly when done. Or, leave them out for 24 hrs in low humidity but i find the oven easier

    Equipment

    1x nonstick, PTFE & PFOA “free” frying pan. These do not have any nasty chemicals leach out when used
    Deep wok
    Muslin bags / cheesecloth
    Roasting bag
    Silicone spatular
    Isopropyl Alcohol 99.9% food grade
    Unbleached coffee filters
    Roasting bag
    Funnel
    Oven thermometer
    Electric hob
    Grinder
    Two curing jars

    So, for this test run i’m using 28 grams / 1 Oz. My buds has been curing for around 5-6 weeks now but 4 weeks is golden

    1. Break the bud up into small pieces and place inside a roasting bag and tie closed
    2. Heat your oven to 110c -115C using your independent oven thermometer. Do not go by your ovens!
    3. Place the roasting bag in the oven on a baking tray for 60 mins
    4. After 60 mins, remove from the oven and alow to cool
    5. Grind the cannabis
    6. Now place the cannabis (in the roasting bag), bowls, funnel, fork and solvent in the freezer, on it lowest setting for 24hrs!
    7. After 24hrs, remove from freezer, place the cannabis into a bowl and pour over enough solvent to cover the contents. Do this as quickly as possible
    8. Gently mix around in the solvent for around 30 seconds then leave to sit. Total time 3 mins
    9. Pour into your muslin bag and strain the liquid out by squeezing the bag
    10. Empty the buds back into the bowl and repeat a further 2x. So 3 washes in total
    11. Strain the liquid through your unbleached coffee filters. This can take quite some time and half way through, i use a new filter to speed things up a little. If possible, allow to strain in the fridge or freezer. We want to keep this all as cold as possible!
    12. Once strained, place back in the freezer for 24 hrs
    13. Add boiling water to the wok and place the frying pan on top to heat through.
    14. Add your solvent to the pan and after a short time, it will start to fizz

    The idea of the wok with boiling water is you turn the heat off before you add the solvent to the frying pan as its highly flammable! Let the heat from the water boil off the solvent. Make you have windows open and having a fan to blow away the fumes is a great idea!

    You’ll have to remove the frying pan at some point and re-heat the water in the wok, then continue to boil off the solvent. The solvent will gradually evaporate and you’ll be left with thick resin/oil.

    Once the solvent had gone you’ll notice small co2 bubbles in the oil. If you want highest THC content then once all the solvent has gone, your finished.
    If you would like a more sedative oil, then continue to heat until all the small bubbles have gone. This will give you more CBN.

    Freezing the flowers and the solvent is called winterisation. This helps clean the fats, wax and lipids from the flowers. It also helps keep down the chlorophyll

    Im sure there are other ways to do this but, this is how i do it. Any other oil makers reading this i would appreciate your input as there are aways ways to improve

    I hope anyone in need of oil has found this useful and you can see how easy it is to make.



















    That's it folks

    Good quality bud should give you 4-5 grams of oil

    You're welcome mate. Give me a shout nearer the time as there are a few delivery methods. Some better than others and also making the bioavailability much better to get the most from the meds

    No mate. I didn't mean to add that photo. That was from a much larger batch. They are 1ml/gram syringes. I get 4ml/grams from each oz.

    I'll ask a Mod to remove it to save confusion

    Sorry mate, I missed this....

    For cancer you will need to consume 1g per day, building up slowly. I guess in some cases more may be required...

    Excellent guide Chew, we have the same teacher...

    There's couple of new improvements that I'd recommend on winterization process, it will yield more oil and keep the chlorophyll out...

    Most people out there do the QWET or Quick Wash Ethanol method which yields about 3-4 grams of oil per ounce or around 13% to 14% extraction yield. The total cannabinoid content of an ounce is about 5-5.5 grams of oil, anything above that is just chlorophyll and plant waxes...

    The "SCET" method or Slow Cold Ethanol will output maximum cannabinoid content while keeping the chlorophyll and plant waxes locked away in a frozen state. Extraction yield will be 17% to 19% while your oil should look more translucent like maple syrup...


    This is new type of "winterization process" or filtering while cold!

    Set the freezer at the lowest temperature. Stick all your ethanol and product in the freezer for at least 12 hours. Once your ethanol reaches the coldest temperature your freezer can provide you are done, its not going to get colder by waiting any longer but you do want your product to freeze so 12 hours should be fine...

    Mix your product with your ethanol in a jar with a lid and give it a good shake, put back in the freezer for 12 hours. After 12 hours shake again and put back in the freezer for another 12 hours, shake one last time and strain to get the big stuff out...

    Strain through a coffee filter, for high amounts you want to do it through several filters at the same time to avoid warming up your ethanol. At those extremely low temperatures things will get stuck in the filter which would be liquid at room temperature...

    After just evaporate the ethanol as per Chew's instructions...

    Hi Dexter,


    I assume you're referring to Cajun? The man is a fountain of knowledge and a total legend

    Thanks for sharing this mate. This is exactly what i was hoping to get from this thread. Others like yourself adding their tips and tricks to produce a better end product.

    Ask as many as you like mate. I may not be able to answer them all as I still have my L plates

    It's sounds like she would benefit from an oil with a good amount of CBD, that will help with pain and inflammation. I think a 1:1 ratio would be good, CBD aways works better when in the presents of THC imo. As for her dose, thats something you would need to work out between you and your Mum. If you're new to CO then you start off on a very low dose like 100mg per day between 3x doses and build up slowly until she finds the sweet spot that works for her. You can take CO in ways that she will not get any euphoria like tacking to the gum or suppositories. The only problem with tacking is, whilst it's quick and easy to do, the bioavailability is poor and really, it's a waste of valuable meds so if she does't want to get baked, suppositories made using the Bio Bomb method would be good for her.

    Most cannabis out there is high THC and more less zero in CBD. The breeders have done this for recreational use. The good news is, CBD is back and there are plenty of good strains out there. Take a look at CBD crew, they're not the only ones but I have grown their CBD Critical Mass and it's an awesome strain for medical use. I'm also growing their "Therapy" as we speak

    Thanks mate but really, i know nothing compared to some. My best mate was diagnosed with cancer around a year ago. I didn't know where to start, there's lot of conflicting info out there. Since then, i read about cancer and cannabis daily. I also get drip fed information and once i understand it, i share it here. Cancer and other serious illnesses affects so many of us now days i feels its vital for everyone to share their knowledge no matter how small it may be. I now make sure i always have enough bud spare, to make enough oil in case the shit hits the fan
