People should start by orally ingesting their dose of Rick Simpson cannabis oil 3 times per day. For the first week each total dose should be the size of a half grain of white rice. After the oil has been taken for a week, start to double the dose. The dose should be doubled every four days until 1 gram/ml per day is ingested. Most people to get to the point where they can ingest 1 gram/ml per day in about 30-35 days. Once ingesting one gram/ml of oil per day is achieved, dosage should continue at that rate until the cancer is gone. Some people have however increased each of their daily doses to 2grams/ml or more.

Since the starting doses of oil are so small it is very easy for cannabis oil to be dosed out of an oral syringe right into empty pill capsules. This allows for the dosing of the cannabis oil to be very consistent and precise for beginners or children just starting the cannabis oil treatment. Precise dosage is important so that the "high" side effect can be avoided as much as possible. Oral syringes also make it very easy to store your cannabis oil discreetly.
