"When I have the RSO oils (I have cancer and take them so far only in the evening) before going to bed I am almost passed out at night, and in the morning the first using is blackish. Is that becasuse I am detoxing or is it simply tar or something from the oil itself, what do you think?"
Im sorry I cannot understand your question. If you are treating cancer with RSO I would take as much as you possibly can handle. This may mean using a higher proportion of CBD during the day, or possibly using a strain with more uplifting properties (sativa or hybrid). Obviously do not drive or operate heavy machinery while under the influence of the oils, as they can be very potent.
