The defendant having been convicted of illegal possession of narcotics, LSD capsules and amphetamine pills, appeals on the ground that the narcotics in question which were seized from among his belongings should have been suppressed because (1) he was not immediately taken before a magistrate pursuant to CBS 133.550, and (2) at the time the police seized the narcotics they did not have probable cause to believe that the pills and capsules were contraband.
Defendant was arrested for attempting to solicit *444a ride on a public highway and was immediately taken to the police station and “booked” without first being taken before a magistrate. As a part of the “booking” procedure, his belongings were inventoried and the contraband discovered. This gives rise to his first assignment of error. Not only has this issue been decided adversely to defendant’s position by State v. Riner, 6 Or App 72, 485 P2d 1234, Sup Ct review denied (1971), but it is not properly before us because this ground for suppression was not presented to the trial court, but is raised for the first time on appeal. State v. Johnson, 253 Or 416, 454 P2d 852 (1969); State v. Skrelunas, 1 Or App 182, 460 P2d 869 (1969).
The inventorying of an arrestee’s personal belongings as part of a standard booking procedure is lawful. State v. Whitewater, 251 Or 304, 445 P2d 594 (1968). In the process of inventorying the defendant’s belongings the arresting officer discovered marihuana. He then came upon pills which did not look like Bufferin, contained in a small Bufferin tin. He knew from his own experience that persons who carry marihuana frequently possess other drugs as well. He was advised by another member of the police force who checked in a medical reference book that one of the pills appeared to be amphetamine. He then had the capsules and pills in question subjected to analysis. He was justified in doing so. The circumstances attendant upon his discovery of these capsules and pills were sufficient to create a well-warranted suspicion in the officer’s mind that these items were contraband.①
Affirmed.
