VAHEGURU JI KA KHALSA, VAHEGURU JI KI FATEH
The leaves to make Shaheedi Degh - what exact cannabis is it? There is the bred for recreational use marijuana strain, which has a very high THC content; and there are some cannabis, of which some varieties have a very low THC contact and a much higher CBD content.
Why ask, you say? CBD also seems to have medicinal properties without the high and THC...well, gets you high, but also seems to have medicinal properties.
If the Nihung Singhs are using specific varieties of cannabis that are bred or known to have low THC and high CBD, there may be more to their use of cannabis that meets the eye for health reasons and may promote health overall.
Would be interesting to delve into this further, as the current medical profession is looking hard at CBDs for a variety of diseases.
