Breathalyzers have long been used to determine someone suspected of drunk driving's blood alcohol level, but the recent legalization of marijuana in multiple states and escalating heroin and prescription opioid abuse epidemic in the U.S. Marijuana is currently the second most commonly detected drug (behind alcohol) in the blood of people involved in crashes, and a 2010 study showed that 47 percent of drivers involved in deadly accidents tested positive for a prescription drug, most often pain relievers. However, developing an effective drug breathalyzer isn't as simple as tweaking the existing alcohol-detecting models. This is because the substances are metabolized differently. To measure blood levels based on breath, you need to know the vapor pressure of the substance - which is how a compound behaves when it moves from being a liquid to a gas, such as when a molecule leaves your blood and is exhaled in your breath. Molecules with a high vapor pressures, like ethyl alcohol are always escaping.
That's why you can easily smell alcohol, whether on a person or an open bottle of rum. But THC (the chemical compound in marijuana that gives the "high") has a very low vapor pressure. It is so low that the technique used for measuring alcohol - putting the substance in a closed container and waiting for the pressure to equalize - doesn't work to measure THC. It would take too long. Recently, scientists determined they could use a technology called PLOT-cryo to analyze the few molecules of THC that make it into the vapor phase. This could pave the way for a marijuana breathalyzer. A small study published in a 2013 issue of Journal of Breath Research investigated whether drug intoxication could be identified through breath. Swedish researchers conducted tests looking for substances like marijuana, cocaine, methamphetamine, methadone and morphine. They used a method of chemical analysis called liquid chromatography-mass spectrometry for the breath and blood plasma tests. However, the researchers could not detect exactly when the person had last taken the drug, which is an issue when determining whether someone is driving under influence.
This is true of THC as well. Clare Waismann, certified addiction treatment counselor and founder of the Waissman Method of rapid detox adds another wrinkle, specific to opioid detection. Despite these obstacles, many companies are working on producing an accurate, reliable breath test for drugs. Dave Claflin, founder of Fastest Labs says that Lifeloc Technologies is one company that's in the research phase of breathalyzer technology for quick testing. Even once a breathalyzer is available, the machine would have to pass federal regulations for the department of transportation, as well as regulations for each particular state, Claflin notes. In 2017, the Dräger DrugTest 5000 started making the rounds by way of San Diego police. It can detect drugs like methadone, amphetamine, methamphetamine, opioids, marijuana and others using a rapid cheek swab test. The test can determine whether drugs are present in a driver's system but not intoxicated he or she is - a blood test must still be done to confirm that. A breathalyzer can detect the presence of alcohol in a person's breath.
Jedediah Sanger (February 28, 1751 - June 6, 1829) was the founder of the town of New Hartford, New York, United States. He was a native of Sherborn, Massachusetts, and the ninth child of Richard and Deborah Sanger, a prominent colonial New England family. During the Revolutionary War he attained the rank of 1st Lieutenant having fought in the Battles of Lexington and Concord, the Battle of Bunker Hill, the Siege of Boston (1776), and during the New York Campaign. After the war, he settled in Jaffrey, New Hampshire, where he began farming, trading, and running a tavern. He was involved in several civic activities and was appointed Lt. Colonel of the New Hampshire militia. After a fire destroyed his property, leaving him bankrupt, he started over in the frontier of New York. Sanger settled in what was then called Whitestown. He became a land agent or speculator, buying large tracts of land on both sides of Sauquoit Creek and reselling smaller lots.
He was involved in land transactions, one of which involved George Washington, for the area that would become New Hartford, New York. Between 1789 and 1820, he operated a paper mill, grist mill, and saw mill there. He also purchased land Sales at Sangerfield, Skaneateles, Chittenango, and Weedsport; He established mills in some of these towns. To facilitate travel between the settlements, Sanger was an investor in the Seneca and Chenango Turnpikes (now New York State Route 12). Sanger gave his name to a town, Sangerfield, New York, a Masonic lodge, and other places in New York. He is noted as the first settler and founder of New Hartford through two historical markers. Among his various business pursuits, he was engaged in agriculture and manufacturing. He was a town supervisor, county judge, and state assemblyman and senator. He helped establish churches and a school. 273 Deborah (née Morse) Sanger and Richard Sanger III (1706-1786), who married c. 1729.
