I love mapacho snuffs so grounding, awesome you have grown your own.
I usually do 50:50 ash to tobacco sometimes even more tobacco if I need alot of grounding.
Mint plants make a nice admixture.
So does a LITTLE bit of cayenne pepper.
I would try a little pinch of our mapacho and see how much you want to mix it with admixtures to get the strength you want.
Also be sure to screen your snuff at around 100 microns to remove stems and particles that will damage the nose. This step is crucial for amazing snuff!
In the province of the mind what one believes to be true, either is true or becomes true within certain limits. These limits are to be found experimentally and experientially. When so found these limits turn out to be further beliefs to be transcended. In the province of the mind there are no limits. However, in the province of the body there are definite limits not to be transcended.-J.C. Lilly
