A San Diego federal drug crimes lawyer becomes essential when facing federal charges that carry mandatory minimums far exceeding penalties under California law. Kenney Legal Defense brings over three decades of criminal defense experience to protect clients from drug crimes prosecuted in federal court, where severe penalties can include decades of imprisonment. Our team understands how federal agencies, such as the Drug Enforcement Administration, build cases in San Diego County. Our law firm provides aggressive federal criminal defense for clients facing drug trafficking, possession, and distribution charges that threaten their freedom and future.
San Diego's unique position as a border city makes it a priority for federal prosecutors targeting drug crimes, with multiple federal agencies coordinating enforcement efforts throughout the region. The Federal Bureau of Investigation, DEA, and Border Patrol work together to investigate drug trafficking organizations, using sophisticated surveillance and informants to build cases. Our criminal defense lawyer recognizes that San Diego residents face heightened scrutiny, with even minor drug possession potentially triggering federal charges when crossing borders or near federal property.
State and federal laws create overlapping jurisdiction for drug crimes, but federal prosecution brings serious consequences, including mandatory minimum sentences that eliminate judicial discretion. Federal investigations in San Diego often span months or years, targeting not just major traffickers but also low-level participants caught in broad conspiracies. Our law offices understand the significant difference between state and federal prosecution, providing legal representation that protects clients from the harsh realities of federal sentencing guidelines.

San Diego federal drug cases reflect the city's position as a major entry point for controlled substances entering the United States from Mexico. Our criminal defense attorneys have successfully defended clients against all types of federal drug charges unique to the Southern District of California.
Border drug trafficking charges arise when individuals allegedly transport drugs across the San Ysidro, Otay Mesa, or other San Diego County border crossings. These cases carry enhanced penalties due to importation charges under 21 U.S.C. § 952, with mandatory minimums doubling compared to domestic trafficking. Federal agencies use advanced scanning technology, drug-sniffing dogs, and behavioral analysis to identify suspected smugglers at ports of entry. Our defense strategies include challenging knowledge of drugs in vehicles, demonstrating duress from cartels, and exposing improper border searches that violate constitutional protections.
Maritime smuggling cases involve allegations of transporting drugs via boats, submarines, or jet skis along San Diego's extensive coastline. The Coast Guard and Navy work with federal law enforcement to intercept vessels suspected of drug trafficking in international and territorial waters. These cases raise complex jurisdictional issues about where arrests occurred and whether U.S. law applies to foreign nationals in international waters. We challenge the maritime jurisdiction, question the chain of custody for the drugs involved, and demonstrate a lack of knowledge when clients unknowingly transport hidden contraband.
Fentanyl prosecutions have become a top priority in San Diego, with federal prosecutors seeking maximum sentences for distributing this deadly synthetic opioid. Even small quantities trigger severe federal charges, with deaths resulting from fentanyl leading to substantial mandatory minimums under 21 U.S.C. § 841(b). The government uses overdose deaths to enhance charges, even when dealers didn't know their products contained fentanyl. Our fraud defense experience helps us challenge the government's proof of knowledge and causation in these tragic cases.
Methamphetamine manufacturing charges target alleged "super labs" in San Diego County's rural areas and connections to Mexican cartels importing precursor chemicals. Manufacturing charges carry mandatory minimums based on quantity. Federal prosecutors use chemical purchase records, utility bills showing unusual power usage, and environmental hazards to build cases. We challenge whether clients actually participated in manufacturing versus mere presence, dispute quantity calculations, and expose illegal searches of rural properties.
Cartel prosecutions in San Diego involve complex conspiracies allegedly connecting local defendants to Mexican drug trafficking organizations. These cases often include charges beyond drugs, such as San Diego money laundering, weapons trafficking, and violence. Federal prosecutors use cooperating witnesses, often cartel members seeking reduced sentences, whose credibility we aggressively challenge. Our defense strategies focus on demonstrating minimal involvement, challenging conspiracy scope, and exposing government deals with more culpable defendants.
San Diego's border region has seen numerous sophisticated drug tunnels, with participants facing enhanced penalties for this trafficking method. Tunnel cases involve conspiracy charges connecting property owners, diggers, and transporters in alleged criminal activity spanning both sides of the border. The government uses ground-penetrating radar, property records, and surveillance to identify tunnel locations and participants. We challenge knowledge of tunnel existence, demonstrate legitimate property uses, and question whether clients knew about underground criminal activity.
San Diego International Airport sees numerous federal drug arrests involving passengers allegedly transporting controlled substances on domestic and international flights. Airport cases often begin with DEA agents conducting "consensual" encounters that we challenge as coercive. Drug possession at airports can trigger federal charges even for amounts that would be misdemeanors under state law. Our defense includes challenging the voluntariness of searches, questioning drug quantity calculations, and demonstrating personal use rather than distribution intent.


Federal drug charges in San Diego face dismissal when constitutional violations, insufficient evidence, or prosecutorial misconduct undermine cases. Our federal crimes defense team files aggressive motions challenging border searches that exceed scope, maritime arrests lacking jurisdiction, and tunnel cases without proof of knowledge.
San Diego federal judges recognize that proximity to Mexico doesn't eliminate constitutional protections or justify unlimited government intrusion. When searches violate Fourth Amendment protections, even with search warrant authorization, evidence becomes inadmissible. The unique aspects of border enforcement create additional challenges prosecutors must overcome, providing opportunities for dismissal when proper procedures aren't followed.
Cooperation in San Diego drug cases can provide substantial benefits due to the value prosecutors place on information about trafficking organizations and border smuggling methods. Federal prosecutors in the Southern District need intelligence about tunnels, cartel operations, and corruption to build larger cases. Our attorney-client relationship includes an honest assessment of cooperation benefits while protecting clients from unnecessary exposure.
The criminal lawyer must carefully evaluate which information provides value without creating additional risks of criminal prosecution. San Diego federal prosecutors particularly value information about transportation methods, stash house locations, and money laundering networks. Strategic cooperation can reduce decades of mandatory minimums to manageable sentences that allow eventual reunification with family.

Trial becomes necessary when constitutional violations require vindication, when evidence is weak, or when mandatory minimums make plea agreements unattractive. Our criminal defense experience includes presenting complex drug cases to San Diego juries who understand border realities. Sex crimes and violent charges sometimes accompany drug cases, requiring comprehensive defense strategies.
San Diego juries often sympathize with defendants caught between cartel pressure and law enforcement, especially when evidence shows minimal involvement or coercion. The proximity to Mexico means many jurors understand how ordinary people become entangled in trafficking through circumstances beyond their control. We present compelling narratives about economic desperation, family threats, and the human cost of drug war policies.
What makes drug charges federal versus state in San Diego?
Federal jurisdiction applies at border crossings, airports, military bases, and federal property, or when cases involve interstate trafficking.
Can California medical marijuana patients face federal charges?
Yes, federal law doesn't recognize state medical marijuana laws, though prosecution of legitimate patients remains rare. Federal charges typically target dispensaries or cultivation operations rather than individual patients.
What happens to property seized in federal drug cases?
Asset forfeiture allows permanent loss of property even without a conviction unless you prove legitimate sources for assets. The process requires separate civil litigation to recover seized property.
