^ im going to have to disagree with slow . ive seen alot of people waste shit loads of coke because they dont get it all the way up into the membranes in the nasal cavity . whenever i was doing coke i would use 1 quick strong sniff to get it up there and needless to say my high was always better than the people who took their sweet ass time with it .
put the small rocks out onto the table or whatever and line em up in a lil bunch, take a dollar and put it ontop of them and then take a card and slide it over the dollar bill so it crushes the rocks. Take out a razorblade and get the white off the dollar bill and cut up whats crushed on the table
i like spice mills. i get the finiest powder that way. if and when i have to use a straw.(i have a glass snuff tube) but when i have only a straw around i hold it over a lighter for jsut a second to melt it just a little so that the straw isnt sharp going up the nose. I like to stick the straw pretty far up there up where you can feel the bone in the nose. and i snort hard and fast. but hey everyone has there one style.
yeah like all these people have said, chop it up very finely with a razor blade. the finer the better because the smaller the particles are the more that will be absorbed by your nasal passage. and faster is by far better because it gets it far up opposed to doing it slowly it gets stuck in your nostrils.
Get yourself a little powder grinder from a headshop. Works wonders for getting the finest, fluffiest powder possible. Mine's been put through so much use that the handle broke off and is now substituted with a paper clip. Will be getting a new one, since they're so handy.
Also, snort moderately hard. Too hard, and it will just fly down your throat, too soft and bits will fall out/not be absorbed properly. Just try a few lines with different intensities and figure out what gets you best.
If it's a big rock, i put a note over it (so it doesn't ping off everywhere), then crush it with a credit card. One it's basically powder, i use a card (wtih no numbers for the powder to get stuck in) put it on top, grind back & forth. Seemjs to powder most things pretty well
If it's a big enough rock to hold, get a sharp swiss-army-knife and lightly scrape the rock and pile up what you scrape off. it'll be as fine as dust.
Otherwise put it in a little plastic baggie and gently tap/crush it over and over with something small and flat ended (like the end of a pen like a sharpie-cap), pick up the bag and flick it with your finger to get it all to the bottom, repeat until it's as fine as you want it and it'll be perfect.
It doesn't matter how fast you snort it, just snort long skinny lines. There are tons of ways to crush it. Personally, I normally put a baggy on top of it and pulverize it with a bic lighter, then I use a razor blade to crush all the little chunks that didn't get pulverized.
AMEN... JYKKE! So much time wasted crushing it to powder, then chopping it into lines, then rolling bills or paper, then discussing "Fast?" or "Slow?". By now, while they are deciding how fine to chop it up and how fast to snort it, my bell is already RUNG!! ZZZZZZZIIIIIIINNNNNGGGGGG!!!
