Man, don't waste your time plugging with dillies. Snorting dillies are the shit. If someone tells you shoot or sell, they aren't doing it right. Here is how you get a dilly to work great snorting. My best connect is 4mg dilly so I've spent some time getting the most out of it without shooting.
Crush it up, I recommend 2... doesn't mean you have to do all 2. Break out very thin, very long lines. I average about 10-12 lines per 2 pills. Clean out your nostril of choice, get your finger in there and make sure no cliffhangers or wall huggers. Do a line then wait 2 minutes or so. Then do another. wait another 2 minutes then do another. On third line take a smoke break. In between doing the lines, after the 2-3 minutes of waiting get in there and clean out that nostril. Sometimes I get lucky and have both nostrils clear but most the time only one isn't stuff, i have no idea why.
I used to just crush a pill and snort it in either one line or two. Then one night i came into like 10 pills and said fuck it im getting right tonight. I think i ended up snorting 7 or 8 pills in the span of 2-3 hours and never got any more buzzed than had i done 2. After that I was done with them until i saw a post on here on how to properly snort them awhile back. Now i fucking love dillys as much as roxys. You snort them right and you have a good nod and get pretty high for 3-4 hours. Not much of a rush especially compared to shooting. And doing this you feel the nod building, so if your good after 5-6 lines, just save the rest for later.
TL:DR: Break out a lot of small long lines, take 2-3 min breaks inbetween rails, and clean out that nose after your 2-3 min breaks.
