I feel that in general, crushing up any kind of pill does tend to make it hit harder/faster. It's not a tremendous difference but it is still noticeable.
As SL55 said, DO NOT CHEW. Why would you chew that nasty shit when you could crush it up and then either parachute/dump or put it in gel caps and swallow that way? Also, who wants nasty pill crap stuck between their teeth? Seriously, dont' chew.
