If you say no...consider yourself fucked. Because the very act of opposing the search gives them probable cause to search you (with a warrant).

That's not true. You have the right to refuse a search. They have to have some kind of evidence or reason, not just that you opposed the search.

It seems to me, that if they thought you were high or whatever...and you refused a search of your car...then they go do whatever it takes to get a warrant and they say "He looked high and he refused the search" It certainly does not help your case. Evidence in and of itself, no, but I can't see it helping you out at all.
