There is a reason we don't see cocaine in pills - orally the distrobution is really very poor.. yeah, if you take enough you will get a high but unless you have money to burn I wouldn't advise it.. if you really want to try then cap about half a gram (yes, 500mg or .5g, any less andthe 'high' isn't defined enough to make it worth yer while - I'm sure you could take less but for me it was a solid half gram that gave a mentionable high... how to describe it? Lets see.. ok, rail a line and wait about 15-20 minutes for the 'high' to subside - where you are now, well, imagine that drawn out for about 30 minutes to an hour, closer to the former..
It's really mild, and fairly short lived - longer then any other method of intake but it's a waste as far as I am concerned - that half gram could be broken into many parts and injected or even snorted ..
