I VERY RARELY got any such sensation... actually, crack usually had no effect on me, or very little.. girls would always take a hit then roll on the floor, ears ringing, puking and shitting like girls do when they get coke in their system ... now when I would IV it was a differn't story, but smoking crack would usually leave me having had no such ringer...
So you can try smoking more - put a big, fat rock in the pipe, blase it, then hold it as long as you can... but you might just be like MOST PEOPLE and you don't get much from crack...

"I am not one of those weak-spirited, sappy Americans who want to be liked by all the people around them. I don't care if people hate my guts; I assume most of them do. The important question is: 'What are they in a position to do about it?'" (William S. Burroughs)
