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.

Can Past Allegations of Sex Crimes Be Used Against You in Minnesota?

One question people charged with a sex crime in Minneapolis, MN, ask is: Can past allegations of sex crimes be used against me? Under Minnesota Rules of Evidence, past sex crime allegations aren't admissible as evidence in court to prove a suspect's character and argue that it contributed to the commission of the current crime. However, there are circumstances in which the court may allow prior allegations or bad conduct as evidence. These circumstances include when the prosecution can demonstrate that prior allegations or acts are key to establishing intent, identity, or pattern of bad conduct related to the current crime.

What If The Alleged Victim Was Drunk? Minnesota Consent & Alcohol Laws

Under Minnesota consent & alcohol laws, it is unlawful to engage in sexual contact or intercourse with someone drunk or intoxicated to a degree that prevents that person from consenting, understanding, or keeping his or her actions in check. Simply put, you should avoid sexual contact with a person who visibly looks impaired by alcohol, drugs, or other intoxicating substances.
