Actually, I don't use pot - I don't have that much left. All I can afford is 1/4 of a cup, but that is enough.
My technique is to place some in my hand and siff it in almots to my throat, then using backflow from my lungs expell it thru mouth. One nosdril at the time. Also one should avoid backblow thru nose - this way liquid is forced into cavities(with all dirt). After I finish, some mucos comes out for about 10 minutes. I feel like my nose gets stuffed slowly, then I clear it up for one last time. It is my daily procedure before yoga practice.
Glad to find people looking for traditional methods of health improvement.
