Common Strategies in Drug Crimes Defense Involving Search and Seizure Issues
June 5, 2026
A strong defense in drug crime matters often begins with a close examination of how law enforcement searched and whether constitutional protections were observed.
At Schwartz, Hanna & Olsen, P.C., we don’t assume that evidence in drug cases was obtained properly. Instead, we review the facts, the procedures, and the circumstances surrounding each search to determine which defense strategies may apply.
With offices in South Plainfield, Hamilton Township, and Somerville, New Jersey, as well as Mineola, New York, we serve clients throughout Middlesex County, Somerset County, Morris County, Essex County, Passaic County, Bergen County, Sussex County, and Hunterdon County.

Evaluating the Legality of the Initial Stop
In many drug crime cases, evidence is discovered after a traffic stop or a street encounter. If law enforcement lacked a valid reason to initiate the stop, any evidence collected may be deemed inadmissible.
At Schwartz, Hanna & Olsen, P.C., our New Jersey criminal defense attorneys will look closely at the police report, body camera footage, and any available witness accounts to assess whether the stop was justified. From there, we will consider how the stop developed. If a routine stop turned into a search, we will analyze whether that escalation was supported by additional facts.
In drug crime cases, this step often reveals whether law enforcement stayed within legal limits or exceeded the scope of the interaction without proper grounds. By focusing on the beginning of the encounter, we can determine whether the evidence gathered later may be subject to challenge.
Challenging Searches That Were Conducted Without a Warrant
In many drug crime cases, searches occur without a warrant, which can raise important questions about the legality of the search. The Fourth Amendment generally protects against unreasonable searches and seizures. That means a warrant is typically required unless a recognized exception applies. Some commonly cited exceptions include the following:
Consent given by the individual
Searches incident to a lawful arrest
The presence of exigent circumstances
Items in plain view
While these exceptions exist, they aren’t unlimited. Our New Jersey drug crime attorneys will carefully review how each exception can be applied to your case. For instance, consent must be voluntary, and exigent circumstances must be supported by immediate concerns.
Examining Search Warrants for Deficiencies
In many drug crime cases, law enforcement will need to obtain a warrant before conducting a search. A valid warrant must be supported by probable cause and must clearly describe the place to be searched and the items to be seized. If either of those elements is lacking, the warrant may be challenged.
At Schwartz, Hanna & Olsen, P.C., our attorneys will also consider how the warrant was executed. Even a properly issued warrant can raise issues if it’s executed beyond its scope. For example, if law enforcement officers search areas that are not listed in the warrant or seize items unrelated to the investigation, those actions may be subject to additional scrutiny.
When handling a drug crime case, our attorneys pay close attention to the affidavit submitted to obtain the warrant. If it contains inaccurate information or omits key facts, that may affect the validity of the warrant itself. This review is critical to assess whether the evidence collected under the warrant should be admissible in court.
Addressing Chain of Custody and Evidence Handling
In drug crime cases, the chain of custody plays an important role in determining whether evidence can be relied upon in court. The chain of custody refers to the documented handling of evidence from the time it’s collected to the time it’s presented. Any gaps or inconsistencies in this process may raise questions about the integrity of the evidence. The factors that could indicate chain of custody or handling issues include:
Missing documentation or incomplete records
Unexplained transfers between individuals
Improper storage or labeling of evidence
These details can affect whether the evidence presented is the same as what was originally collected. If there’s uncertainty, that may influence how the evidence is viewed. In addition, it's essential to consider whether proper procedures were followed during testing. Laboratory analysis must adhere to established protocols. If those procedures aren’t followed, it may raise concerns about the reliability of the results.
