The defendant's appeal is dismissed.

1. The summary of the grounds for appeal (e.g., imprisonment with prison labor, additional collection of KRW 2,351,50) imposed by the lower court is too unreasonable.

2. Although there are no circumstances to consider the circumstances such as the Defendant’s confession and the provision of information on the channels of narcotic purchase to cooperate in the investigation, considering the quantity, kind, frequency, etc. of narcotics purchased and administered by the Defendant, the nature of the crime is more serious in light of the quantity, type, and frequency, etc. of narcotics purchased and administered by the Defendant, and there is a need to punish and eradicate narcotics crimes with severe adverse effects on society as a whole, and each of the crimes committed again against the Defendant during the period of suspension of execution due to the same kind of crime, and all of the sentencing conditions indicated in the instant case, including the Defendant’s age, character, and conduct, environment, the background and consequence of the instant crime, and the circumstances of the crime.

3. In conclusion, the defendant's appeal is dismissed in accordance with Article 364 (4) of the Criminal Procedure Act since it is without merit. It is so decided as per Disposition.
