Most drug cases are won or lost based on what happened during the search and what the defendant said afterward. There are two fatal mistakes you must avoid right now:
"If you've been charged or are under investigation, stop talking to law enforcement and call us. Even if you've already talked, call. We start working from where you are."
Marijuana, methamphetamine, cocaine, opiates, or prescription pills found not in their original container.
Intent to distribute charges often hinge on a single text message, packaging, or scales. We fight the intent.
Possession of pipes, syringes, or other items used for taking or preparing drugs.
Serious allegations of moving or selling controlled substances across county or state lines.
Drug-related probation violations from failed UAs or possession. We work to keep you out of custody.
Montana drug crimes are governed primarily by Title 45 (criminal code) and Title 50 Chapter 32 (controlled substances act). Penalties depend heavily on the substance, the amount, and the alleged intent—whether they claim it was for personal use or for distribution.
Marijuana is legal for adults 21+ in limited amounts in Montana. However, charges still frequently happen for: possessing amounts over the legal limit, possession in prohibited locations such as schools or other restricted areas, possession by minors, or distribution outside the licensed system.
Methamphetamine and fentanyl are Montana's absolute highest enforcement priorities right now. Prosecutors push hard on these cases, and the political pressure to convict is immense. You need aggressive representation immediately.
We file aggressive motions early. When the evidence gets suppressed, the case often goes away. Here is how we tear apart the prosecution's case:
If police searched your car, home, or pockets without proper consent, a valid warrant, or probable cause, the evidence obtained is fruit of the poisonous tree. It must be thrown out.
Drugs found in a shared apartment or a car with multiple passengers do not automatically belong to you. The state must prove you knew about them and had control over them.
From the crime scene to the evidence locker to the state crime lab. If evidence handlers make documentation mistakes, the substance cannot be used against you in court.
Many drug cases rely on CIs—often people working off their own charges by setting up others. Their stories frequently fall apart under aggressive cross-examination.
When undercover officers or informants push, harass, or coerce a defendant into committing a crime they would not have done otherwise, it is unlawful entrapment.
If you were subjected to custodial interrogation without being read your rights, your statements (and sometimes evidence found because of them) can be suppressed.
Article II, Section 10 of the Montana Constitution provides an explicit right to privacy that can give defendants meaningful protections in search-and-seizure cases.
"We use Montana's privacy protections aggressively. It's one of the most underutilized tools in drug defense."
Not every case needs to end in a trial. Many first-time and lower-level drug offenders qualify for pretrial diversion programs or specialized drug courts in Montana.
Diversion typically means: you complete an approved treatment program, stay clean for a set period, and the charges are dismissed entirely.
Most clients fear the conviction more than the jail time, because of how it follows them. A drug conviction can permanently affect:
