Crushing it thoroughly should effectivly make it IR. Don't snort, for your own sake. And yes, it has recreational value. I find it to be much more enjoyable than alcohol / weed. I'd go as far as to say it's dam awesome. Some people don't seem to like it as much. 30mg will make me semi-euphoric and is a great point for schoolwork. 40mg has been enough to make me full-on euphoric, probably a good place to start at. Sometimes it still gets me there, sometimes i need 50mg (IR). Take it in the morning, otherwise you'll need to smoke a fat bowl to fall asleep. I'm starting to take magnesium supplement's because it's supposed to maintain/reduce tolerance. I havn't built up much (if any) so hopefully I can keep right near my starting point. I use addy only 2-3 times a week which should help. If you are coming down and want to re-dose, remember that there are still amphetamines in you! 20mg 6 hours after the first 40 re-peaks me.
crushing up the little beads with a plate and spoon effectively bypasses the XR, making it instant release... however I wouldn't bother snorting all that powder, if you eat the powder you just IR'ed then it'll be great enough.
