Get a dremel with a good sanding edge. and grind that sucker up good.. It does a great job.. Then make tiny lines. Do one tiny line at a time. Wait for a minute or two, repeat.. I have heard great results from this. very little to none nasal blockage (if done right) and you get the full effects, (it just takes an extra few minutes to hit you).. I've heard this works from many sources. One trusted individual said he gives it a 9/10 This is for snorting only.. Iv'ing is still being worked on... cost of a dremel is less than a hundred bucks, i think.... DONT TRY THIS FOR IV. IT WILL JUST TURN INTO A MESS.... But snorters, rejoice!!!!
