Check out Rick Simpson oil online. It is used as a cancer fighter for many. You can make capsules and creams etc from the oil. Some people just put a drop on the tongue. It has a high concentration of THC. The recipe is on line. I have never made it.
RSO Rick Simpson Oil. It can be made in several different ways but I read it is healthier to buy the pressed oil instead of those made with alcohol based cooked RSO as it leaves some toxins from the burning process.
