The defendant, Billy Joe Evans, appeals his conviction of traf *819 ficking in marijuana, unlawful possession of alcoholic beverages and possession of a distilling apparatus. Sheriff Larry Sanders of Hart County, Georgia, had received information about marijuana growing on property adjacent to a mobile home in which the defendant lives. He placed the property under observation and then obtained a search warrant. It was issued in the name of Manuel Evans, the defendant’s father. The sheriff was assisted by GBI agents in executing the search warrant. After the defendant observed the officers in the execution of the warrant, he went to the sheriff and admitted that “it’s mine . . . everything was his.” The officers confiscated a distilling apparatus, containers filled with alcohol which tested out at 42 proof to 92 proof, and several boxes of marijuana leaves; and pulled up approximately 1,600 growing marijuana plants.
GBI Agent Wakefield saw the defendant the following day in the jail in Hart County and advised him of his Miranda rights and obtained a statement from him in which he admitted the marijuana and the “still” were his property alone. Defendant told him he ran the still two or three times a month and made six gallons on each run but had not sold any of the marijuana. The defendant appeals his conviction of all counts. Held:
1. It is alleged that Evans’ confession is inadmissible because he was under the influence of drugs administered by his doctor prior to giving a statement to the GBI. The defendant was jailed on the afternoon of August 31, 1982, and Sheriff Sanders saw that he was upset and called a doctor. The doctor found defendant tense, anxious and restless, and gave him a shot of chlorpromazine, a tranquilizer. It has an effect upon the brain that produces a tranquilization-sedation effect. The doctor testified that he “would anticipate more the tranquilization and sedation without that much impairment to his mental faculties, but [if] a person who was sensitive to it,” his ability to think and reason could be affected. If this occurred, an observer would notice an accompanying sedation or drowsiness. When the doctor saw him on September 1, during the mid-part of the day, he had given him one shot early in the evening of the previous day, another shot near midnight, and the third shot of the tranquilizer prior to him giving his confession to the GBI. He was of the opinion that defendant was in possession of his faculties and there was mental clarity when he saw him before giving him the third shot. The GBI agent was of the opinion that defendant was not intoxicated by alcohol or drugs and that nothing was physically wrong with him when he made his statement. The trial court found the confession to be freely and voluntarily given and admitted it in evidence.
Evans contends that it was error to admit his confession because “it did not meet the expressed standards in
Beecher v. Alabama,
Whether a suspect is mentally capable of, and did make a knowing and intelligent waiver of, his
Miranda
rights is a factual and credibility determination for the trial court and will not be disturbed on appeal unless clearly erroneous.
Findley v. State,
2. The state confiscated almost two pounds of marijuana which had been stripped from the plants’ stalks and placed in boxes. The 1,600 growing plants had been burned. The State Crime Lab determined that the substance confiscated was marijuana. The search and arrest of the defendant occurred on August 31, 1982. Indictment was returned during the February Term of 1983. On February 20, 1984, defendant filed a “Motion to Permit Lab Analysis,” in which he asked “to examine the material evidence against him and to verify the tests that have been performed to determine the alleged identity of the substances involved in the indictment as being marijuana and non-tax paid liquor.” However at trial, the state argued that the request was *821 not timely, as the motion was not filed until February 20, 1984, and the case had already been continued from the last term. Counsel for defendant then argued that “even if my motion was timely, the evidence had been destroyed the same day that it was recovered so it would have been impossible for me to be timely.” The court inquired of counsel that what he had requested was to analyze the substance, so he should address “the two pounds” possessed by the crime lab. Counsel replied: “No sir, this has to do with trafficking because of the quantity being two thousand pounds. That’s what I want to have my analysist [sic] come in and determine the weight of the marijuana, but it was destroyed on the same day it was received, therefore I’m trying to show the court it’s impossible for me to have the expert to come in and do that because the state has destroyed the evidence.”
Counsel has confused the subject matter of his motion. Prior to trial, he requested to analyze and “verify the tests that have been performed to determine the alleged identity of the substances involved. ...” But, at trial, since defendant was charged with possessing more than 2,000 pounds of marijuana, he said the object of his analysis is now “the quantity being two thousand pounds.”
Our Supreme Court, in
Patterson v. State,
We find no merit to the enumeration for three reasons. First, it was untimely.
Partain,
supra, p. 208. Second, counsel abandoned the basis for the motion filed before trial. And last, although this court has denounced the practice of destroying evidence without prior notice to an accused, we found no prejudice to an accused charged with
*822
trafficking in marijuana by possessing more than 100 pounds where the state retained only 100 grams. See
Lang v. State,
3. The trial court properly permitted the GBI agent to testify as to the weight of the marijuana found growing in the fields. It is within the sound discretion of the trial judge as to whether a witness has such learning and experience in a particular art, science or profession as to entitle him to be an expert.
Redd v. State,
4. We have examined the last enumerated error and find it to be without merit.
Judgment affirmed.
