Drug Sale and Use Convictions Upheld Under the Comprehensive Dangerous Drugs Act

In a recent decision, the Supreme Court affirmed the conviction of an accused found guilty of both illegal sale and illegal use of dangerous drugs under Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002. The case clarifies how the prosecution may secure convictions for both offenses arising from a single buy-bust operation, and underscores the importance of complying with the chain of custody rule.

The Facts of the Case

In June 2019, the Philippine Drug Enforcement Agency received a tip that Edgardo Bernardino y Tamayo, also known as "Totong," was selling marijuana in Pasig City. A buy-bust operation was planned, with an officer designated as poseur-buyer. The officer contacted Bernardino and arranged to purchase one kilo of marijuana for PHP 25,000.

On the agreed date, the poseur-buyer and a confidential informant went to Bernardino's house. Bernardino handed over a paper bag containing dried leaves later confirmed to be marijuana weighing 678.45 grams. After the marked money was exchanged, the pre-arranged signal was given, and the rest of the buy-bust team entered the house and arrested Bernardino.

The seized items were marked, inventoried, and photographed at the place of arrest in the presence of Bernardino, a barangay official, a media representative, and a Department of Justice representative. Bernardino's urine sample also tested positive for marijuana and THC metabolites in both screening and confirmatory tests.

The Issue Before the Court

The central question was whether the Court of Appeals erred in affirming Bernardino's conviction for illegal sale and illegal use of dangerous drugs.

The Ruling on Illegal Sale of Dangerous Drugs

The Supreme Court upheld the conviction for illegal sale under Section 5, Article II of RA 9165. To secure a conviction, the prosecution must prove two things: the identity of the buyer, seller, object, and consideration; and the delivery of the thing sold and payment. Here, all elements were established—Bernardino sold marijuana to the poseur-buyer during a legitimate buy-bust operation.

The Court also emphasized that the identity of the confiscated drugs must be proven beyond reasonable doubt through an unbroken chain of custody. The chain has four links: seizure and marking of the drugs; turnover to the investigating officer; turnover to the forensic chemist for examination; and turnover to the court.

Because the operation occurred after the effectivity of RA 10640, the amended rules applied. The inventory and photography were witnessed by the accused, a media or DOJ representative, and an elected official—all present in this case. The Court found the chain of custody unbroken from seizure to presentation in court.

The Ruling on Illegal Use of Dangerous Drugs

The Court likewise affirmed the conviction for illegal use under Section 15, Article II of RA 9165. A conviction requires that the accused was apprehended or arrested for an offense under Article II of the law, and that both a screening test and a confirmatory test yielded positive results.

Bernardino was arrested for illegal sale of dangerous drugs—an offense under Article II. Both his screening and confirmatory urine tests were positive for THC metabolites, a component of marijuana. This was sufficient to establish illegal use.

The Court clarified that an accused may be separately prosecuted and convicted for illegal sale and illegal use arising from the same incident. The exception under Section 15 applies only when the person tested is also found in possession of a quantity of drugs under Section 11, in which case the possession charge applies instead.

The Penalties Imposed

Bernardino was sentenced to life imprisonment and a fine of PHP 1,000,000 for illegal sale of dangerous drugs. For illegal use, he was sentenced to six months of rehabilitation in a government center.

Practical Takeaways

• Buy-bust operations remain a valid method for arresting drug offenders, provided the elements of the crime are proven and the operation is legitimate.
• Chain of custody compliance is critical. The marking, inventory, and photography must be done at the place of arrest, witnessed by the required persons under RA 10640.
• Separate convictions for sale and use are possible. An accused arrested for illegal sale who tests positive for drug use may be convicted of both offenses under Sections 5 and 15 of RA 9165.
• Both screening and confirmatory tests are required for a conviction for illegal use of dangerous drugs. A positive confirmatory test is prima facie evidence of drug use.
• Denial is a weak defense. Without strong evidence of non-culpability, a bare denial cannot overcome the prosecution's evidence.
