The defendant's appeal is dismissed.

1. The sentence imposed by the lower court (one hundred months of imprisonment, additional collection of KRW 400,00) on the summary of the grounds of appeal is too unreasonable.

2. The fact that the judgment of the defendant voluntarily surrenders to the police and recognized and reflected the crime is favorable to the sentencing.

However, considering the various circumstances that are disadvantageous to sentencing, such as the defendant's age, sex, environment, motive, means and consequence of the crime, and the circumstances after the crime, the sentence of the court below is too unreasonable, in light of the fact that the defendant again committed the crime during the period of repeated crimes for the same kind of crime, the defendant was sentenced twice to the punishment for the same crime, the defendant has a record of criminal punishment once suspended execution, and narcotics-related crimes have a high risk of social disorder and recidivism, and thus requires strict punishment.

3. In conclusion, the defendant's appeal is dismissed in accordance with Article 364 (4) of the Criminal Procedure Act on the grounds that the defendant's appeal is without merit.
