Cannabis oil and raw juicing

Cannabis oil is a concentrated extract obtained by solvent extraction of the buds or leaves of the cannabis plant. It is not actually an oil, but derives its name from its sticky and oily appearance.

Some patients firmly believe that cannabis oil is capable of curing cancer, a claim often backed up with several anecdotal patient stories. Laboratory studies do indeed show a potential effect of cannabinoids on isolated cancer cells in a petri-dish and in lab animals, but it is too early to claim that consumption of cannabis medicine may cure cancer in the much more complex situation of human cancer.

Various solvents have been recommended for making cannabis oil, such as petroleum ether, naphtha, alcohol and olive oil. A recent study comparing five commonly used preparation methods for cannabis oils found significant differences in cannabinoid and terpene composition of the final products. Also, the presence of residual solvent was found to be a significant concern, particularly in the case of using naphtha for extraction. The final conclusion of the study was to prepare extracts directly in olive oil, heated in a boiling water bath for an hour or two; this guarantees the highest recovery of active compounds, and no risk of organic solvent residues.
An interesting new development is the use of raw cannabis buds and leaves, prepared as a drink by juicing them in a blender with water of fruit juice, or consumed directly as a salad. In contrast to the other administration forms mentioned above, this preparation does not undergo any form of heating, and therefore contains all cannabinoids in their original (acid) form. The possible effects of this interesting administration form have not yet been studied in any way.
