Dried medical cannabis flower looks like small, dried cones of green herbs. You normally get dried medical cannabis flower in a hard plastic container with a lid. The container will be opaque to prevent light from damaging the dried medical cannabis flower. You need to weigh out exactly how many grams you’re going to take each time. We recommend you use a weighing scale that can read at least one number after the decimal point (for example, 0.1g). Medical cannabis oil looks like a light, yellow liquid in a brown medical bottle, which protects it from light. You use an oral syringe (there is no needle involved) to help you accurately measure out the right amount of cannabis oil. Normally this is 0.05ml or 1ml to start off with. The amount of medical cannabis you use will depend on the strength and type of medical cannabis you have been prescribed, and the condition you are being treated for.
