This is a proceeding to declare the forfeiture of a Peterbilt Tractor (hereafter tractor) and a Utility Van Trailer (hereafter trailer) coupled to and pulled by the tractor at the time of the incident in question. The proceeding was initiated by the district attorney of Luna County for forfeiture of vehicles used in the alleged illegal transportation of "dangerous substance." This was pursuant to §§ 54-7-26 and 54-7-26.1, N.M.S.A. 1953 Comp. (Repl. Vol. 8, 1971 Pocket Supp.). Notice of seizure and intended forfeiture was served on George R. Dickerson, the owner and driver of the tractor and the trailer. The forfeiture proceeding resulted from the finding and seizure by state policemen of "dangerous substance" being transported in the trailer. The "dangerous substance" was 214 bottles of pills and tablets all containing amphetamines. Some of these were also referred to as "dexedrine," a trade name for certain tablets containing amphetamines. The search leading to the seizure of the amphetamines was conducted without a search warrant and occurred before the arrest of either Dickerson or the lady in his company.
