    About a year ago we spoke briefly about decarbing my rso I was making it for my wife who has stage 3 lung cancer.She had a scan about a month ago and the doctors were very impressed with her progress.My question is this ,I’ve been following ricks directions for making the oil using vm@p naptha,I just read on another cure for cancer site that I should be using light naptha, not the vm@p.I did make a batch with everclear, and it seemed to be a much less toxic adventure,It seemed to boil off better and more consistenly. The fumes also seemed easer to deal with.I find this vm@p stuff to be pretty nasty.The everclear is also very expensive.There is such a pissing match going on about witch solvent to use it can pretty frustrating. I think we are on the right path I just need someone who I can trust and I think thats you.I thank you for all your doing.Whats the difference in the two napthas,and should I be looking for the light stuff? Once again I really can’t thank you enough .


    • Unfortunately, the word Naphtha, only means that what ever is in the mixture, boils between 30C and 200C and VM&P means Varnish Makers and Painters.

      Even Light Naphtha only narrows it to between 30C and 100C, and there are things within that boiling point range, like benzene for instance, which are known carcinogens.

      If you want to do a Rick Simpson type extraction, I would recommend using n-Pentane, or n-Hexane, the two simple Alkanes that boil between 30C and 100C.

      You can sometimes get a blend of those two marketed as Petroleum Ether, but the important thing is that you get a MSDS sheet for what ever you get, to see what is in it.

      Ethanol is expensive, but you can recover and reuse it to extract with again to lower the costs.

        Thanks for the quick response,do you have any opinions on using the everclear and should I change any of my[ ricks] procedures, for instance the 2 to 3 min. wash? Any thoughts on where to obtain Petroleum Ether?I’m also in the pacific north west and I too will look into this.The more I read this site the dumer I feel , but quickly learning , truly amazing the info you provide us with.Thanks again.

    Hello comrades, I was wondering if one can use acetone (C3H6O, vap. temp about 56C/132F) as a main solvent to get non-decarboxylated oil for further use with other edible oils or glycerin. I know for sure the oil from acetone extraction is fine to blend with flavoured tobacco to smoke. Basically, my question is how safe this extraction will be for indigestion.

    Hello Greywolf, I’m from SocCal, we have SCE CO2 extractor. We have been making a very good grade of oil with this machine. I was wondering, is it possible to convert our oil to a shatter or a wax through winterizing and vac purging? We produce 3 types of oil at this time. Raw, purified and a tank formula. We decarb all of it and we winterize the purified and tank oil. I have been fooling around trying to get a more solid product, the best I have gotten so far is a very thick waxie paste. Any Ideas? Would love to hear your input on this and we would share our results with you as well.


    • A couple of thoughts. The first is that I would first try winterizing with ethanol, and cold vacuum boil away the alcohol at about 115F and -29.5″Hg, so as to keep the material in carboxylic acid form. When the solvent bubbles stop, and only decarboxylation bubbles remain, remove from the chamber and let air and solidify.

      The second is that I will hook you up with someone who does cannabis SCFE CO2, to discuss specific extraction criteria. Check you e-mail.
