Np man, I like to answer. If you use the right nostril, you put your left ear down yeah. Regarding the membranes for absorption. Yes, thats why you need to put the roll slightly inside the nose and after you shake the powder in, you slightly pinch the nose and then snort a drop or two (warm is best, because it opens the membranes further, plus dissolves better) water. The water is not always necessary, Id say it depends on the amount a lot, if you use a little, you wont even need it. If you dont have water, this might sound slightly gross, use saliva (but not after eating sth lol). That can be even better in some ways because it dissolves it better.
The main reason why I like this technique is because snorting powder, no matter how careful you are or how you position the tube for snorting, you always get some in your lungs. After years of using that can cause some major problems.
Another thing also regarding snorting the water. Besides washing away the dope down your throat its smart to also be careful not to tilt your head too far back/or for too long and snort too much water because it might "overflow" and the mixture will flow into your inner ear. So when snorting water dont tilt your head back too much. I prefer to first shake the powder in, pinch the nose a bit and snort a little, then snort a drop of warm water and then tilt my head back (all these steps are a matter of seconds), sideways or forwards for 10-15 seconds so if theres a lot of powder you keep it at least somewhat from going down the throat.
