In what circumstances will a court grant a search warrant for an alleged drug dealer for a period of time?

In addition, the affidavit discusses both the length of time in which evidence of drug trafficking may remain at a location, and that such evidence is likely to be found in, e.g., homes, businesses and cars. This is less a problem of staleness, as argued by the parties, than it is a question of an ongoing activity. Cf. United States v. Angulo-Lopez, 791 F.2d 1394, 1399 (9th Cir.1986) ("With respect to drug trafficking, probable cause may continue for several weeks, if not months, of the last reported instance of suspect activity"). In light of these considerations, the district court's finding of probable cause was not erroneous.
