As there are no scientific studies done yet on the Pechoti method, the success of the method is mostly based on experience. The belly button method might not be as bioavailable as edibles or inhalation of cannabis. This does not mean that you cannot experience with dabbing some cannabis oil on your belly button. It is not dangerous or intoxicating. Try to use the purest form of cannabis oil for maximum efficacy. Something like Rick Simpson oil would work perfectly. The most organic and cleanest oil should work best.
