Damn right they are. Exigent circumstances. [1]

Police routinely coerce people into consenting to searches during traffic stops when there is no RAS. If there's a K9 unit around it's even easier; look at how often they just happen to trigger when there's no contraband at all [2]. Does a 56% false positive rate sound reasonable?

And, once they've gained access they've got wide leeway to seize whatever they want in the name of the war on drugs. At that point the owner must pay a bond to contest the seizure, and then has the burden of proving that they were not party to the crime. Note that no warrant is required for property seizure, merely probable cause [3].
