The effect will be spaced out over a period of time, hence "extended" release...you can crush it up and either put it really far back on your tongue and swallow fast with some water, or put the powder in a really really really tiny piece of toilet paper and swallow it that way. Xanax tastes like absolute fucking shit, I agree...plus, snorting them is pointless anyway, they have a super high oral bioavailibility.
EDIT: Violenza, maybe the were out of the brand name, or just had a different generic in stock? Where I fill my prescription regularly always tells me if the pills are going to look different and sometimes even puts a sticker on the bottle about it, and it's usually just made by a different company.
