How have the courts treated evidence of illegal drugs seized from a defendant in a search warrant?

The uncontested testimony of the two police officers discloses that all defendants were arrested with narcotics and assorted paraphernalia in their possession. Defendant does not deny this, but argues that there was no reasonable cause for his arrest without a warrant, and thus the evidence, (Exhibits 1A-B-C-D-E--heroin, balloons, a funnel, paper, a strainer, hypodermic needles, eyedroppers and a metal teaspoon taken immediately after his arrest), was illegally seized after an unlawful search, under the rule of People v. Cahan, 44 Cal.2d 434, 282 P.2d 905, 50 A.L.R.2d 513.
