When Minnesota field tests identify other substances as illegal drugs

In November, a Minnesota man was pulled over for leaving a grocery store parking lot without turning on his headlights. According to Raw Story, police ended up searching his vehicle and found a bag of white powder. Law enforcement conducted a field test, which revealed that the substance may have been an amphetamine. As a drug crime lawyer in Minneapolis may have seen, findings such as these can lead to felony drug charges.

This man, who claimed he had done nothing wrong, was charged with two felony counts of drug possession and was detained in jail for three months. However, in-depth testing revealed that the white powder was actually legally available vitamins, and not drugs. The man was released, but he will never get back those three months of his life.

Testing gone wrong

Unfortunately, field drug tests can often produce unreliable results. For example, the Star Tribune reported in 2011 that a Minnesota woman crossing into Canada was arrested when an old bottle of motor oil tested positive for heroin. After spending 12 days in jail, the woman was finally let go because a Canadian laboratory determined the bottle only contained old motor oil.

A recent report from Fox News details how unreliable field drug tests can be. One reason for a false positive, according to a toxicologist, is that the tests simply change color instead of actually identifying substances. Another report from StoptheDrugWar.org reveals the following:

  • Newspaper, chocolate and natural soap can test positive for marijuana.
  • Oregano can test positive for cocaine.
  • Poppy seeds can appear as opiates.

Ibuprofen, cold medicine, diet pills, sleep aids and a host of other items can trigger a positive field test. StoptheDrugWar.org notes that in one study, researchers found that 70 percent of field tests done in a controlled environment generated false positives.

Defending a false positive

Any drug crime lawyer in Minneapolis is aware that the use of faulty drug testing violates U.S. Supreme Court rulings that aim to protect citizens from experiencing wrongful prosecutions and conviction.

False positives are not restricted to field tests, as they can occur in urine and blood testing as well. People wishing to defend drug charges are wise to do so. Testing positive for drugs can prevent someone from obtaining employment and result in hefty fines and even time in prison.

Until law enforcement discontinue the use of such unreliable testing, many more people may be subjected to wrongful arrests and convictions that can haunt them for the rest of their lives. Anyone with questions on this matter should consult with a drug crime lawyer in Minneapolis.

What to Do If You Have Been Charged with a Criminal Offense

People facing drug crime charges who were victims of unlawful search or seizure may wonder, “What role does search and seizure law play in drug cases?” Under the Fourth Amendment, search and seizure law protects you from unreasonable searches and seizures by law enforcement officers. The Minnesota constitution provides similar protections.
One question that may linger on your mind upon discovering you are under drug crime investigation is: “What should I do if I’m arrested on drug charges?” The first thing you should do if you’re arrested on drug charges in Minneapolis is stay calm and cooperative. Then, document the arrest while the event is still fresh in your mind. Next, hire a lawyer who has built a successful practice around helping criminal defendants facing drug related charges.
If you are facing a sex crime charge or suspect the police are investigating you, you might wonder: “Can I be charged with a sex crime if the other party consents?” While you might have consensual sex with someone, sex crime charges can still be filed against you in Minnesota. Legal concerns, such as the complainant’s age, mental capacity, and legal authority, are usually considered during court proceedings for sex crime cases. All those issues can impact your case.
