Drug Testing and Drug Screening for Teens. Certain drugs such as progestins used for hormonal birth control Hormonal Methods of Contraception Contraceptive hormones can be Taken by mouth oral contraceptives Inserted into the vagina vaginal rings or barrier contraceptives Applied to the skin patch Implanted under the skin read more may be given by inserting plastic capsules under the skin implantation. Although this route of administration is rarely used, its main advantage is to provide a long-term therapeutic effect for example, etonogestrel that is implanted for contraception may last up to 3 years.
The intramuscular route is preferred to the subcutaneous route when larger volumes of a drug product are needed. Because the muscles lie below the skin and fatty tissues, a longer needle is used.
Drugs are usually injected into the muscle of the upper arm, thigh, or buttock. How quickly the drug is absorbed into the bloodstream depends, in part, on the blood supply to the muscle: The sparser the blood supply, the longer it takes for the drug to be absorbed. For the intravenous route, a needle is inserted directly into a vein. A solution containing the drug may be given in a single dose or by continuous infusion.
For infusion, the solution is moved by gravity from a collapsible plastic bag or, more commonly, by an infusion pump through thin flexible tubing to a tube catheter inserted in a vein, usually in the forearm. Intravenous administration is the best way to deliver a precise dose quickly and in a well-controlled manner throughout the body.
It is also used for irritating solutions, which would cause pain and damage tissues if given by subcutaneous or intramuscular injection. An intravenous injection can be more difficult to administer than a subcutaneous or intramuscular injection because inserting a needle or catheter into a vein may be difficult, especially if the person is obese. When given intravenously, a drug is delivered immediately to the bloodstream and tends to take effect more quickly than when given by any other route.
Consequently, health care practitioners closely monitor people who receive an intravenous injection for signs that the drug is working or is causing undesired side effects. Also, the effect of a drug given by this route tends to last for a shorter time.
Therefore, some drugs must be given by continuous infusion to keep their effect constant. For the intrathecal route, a needle is inserted between two vertebrae in the lower spine and into the space around the spinal cord.
The drug is then injected into the spinal canal. A small amount of local anesthetic is often used to numb the injection site. This route is used when a drug is needed to produce rapid or local effects on the brain, spinal cord, or the layers of tissue covering them meninges —for example, to treat infections of these structures. Anesthetics and analgesics such as morphine are sometimes given this way.
A few drugs are placed under the tongue taken sublingually or between the gums and teeth buccally so that they can dissolve and be absorbed directly into the small blood vessels that lie beneath the tongue. These drugs are not swallowed. The sublingual route is especially good for nitroglycerin , which is used to relieve angina, because absorption is rapid and the drug immediately enters the bloodstream without first passing through the intestinal wall and liver.
However, most drugs cannot be taken this way because they may be absorbed incompletely or erratically. Many drugs that are administered orally can also be administered rectally as a suppository. In this form, a drug is mixed with a waxy substance that dissolves or liquefies after it is inserted into the rectum. A suppository is prescribed for people who cannot take a drug orally because they have nausea, cannot swallow, or have restrictions on eating, as is required before and after many surgical operations.
Drugs that can be administered rectally include acetaminophen for fever , diazepam for seizures , and laxatives for constipation. Drugs that are irritating in suppository form may have to be given by injection. Some drugs may be administered vaginally to women as a solution, tablet, cream, gel, suppository, or ring. The drug is slowly absorbed through the vaginal wall.
This route is often used to give estrogen to women during menopause to relieve vaginal symptoms such as dryness, soreness, and redness. Drugs used to treat eye disorders such as glaucoma, conjunctivitis, and injuries can be mixed with inactive substances to make a liquid, gel, or ointment so that they can be applied to the eye.
Liquid eye drops are relatively easy to use but may run off the eye too quickly to be absorbed well. Gel and ointment formulations keep the drug in contact with the eye surface longer, but they may blur vision.
Solid inserts, which release the drug continuously and slowly, are also available, but they may be hard to put in and keep in place. Ocular drugs are almost always used for their local effects. For example, artificial tears are used to relieve dry eyes. Other drugs for example, those used to treat glaucoma [see table Drugs Used to Treat Glaucoma ], such as acetazolamide and betaxolol , and those used to dilate pupils, such as phenylephrine and tropicamide produce a local effect acting directly on the eyes after they are absorbed through the cornea and conjunctiva.
Some of these drugs then enter the bloodstream and may cause unwanted side effects on other parts of the body.
Drugs used to treat ear inflammation and infection can be applied directly to the affected ears. Ear drops containing solutions or suspensions are typically applied only to the outer ear canal. Before applying ear drops, people should thoroughly clean the ear with a moist cloth and dry it.
Unless the drugs are used for a long time or used too much, little of the drugs enter the bloodstream, so bodywide side effects are absent or minimal. Drugs that can be given by the otic route include hydrocortisone to relieve inflammation , ciprofloxacin to treat infection , and benzocaine to numb the ear.
If a drug is to be breathed in and absorbed through the thin mucous membrane that lines the nasal passages, it must be transformed into tiny droplets in air atomized. Once absorbed, the drug enters the bloodstream. Drugs administered by this route generally work quickly. Some of them irritate the nasal passages. Drugs that can be administered by the nasal route include nicotine for smoking cessation , calcitonin for osteoporosis , sumatriptan for migraine headaches , and corticosteroids for allergies.
Drugs administered by inhalation through the mouth must be atomized into smaller droplets than those administered by the nasal route, so that the drugs can pass through the windpipe trachea and into the lungs. Over 22 million Americans reported using Marijuana in the past month, making it the most commonly used illicit drug. In many states it has been legalized for recreational and medicinal use, and many others have only legalized medical Marijuana.
However, there are still states across the country where Marijuana is illegal, and employers or court systems may need to conduct a drug test. Tests for Marijuana are actually testing for the chemical tetrahydrocannabinol THC that makes people feel high. The results of a drug test depend on many factors, including how much body fat a person has, how often someone smokes, and how much they smoke.
First-time Marijuana users are more likely to pass a drug test, compared to a person who smokes Marijuana multiple times per week. The timeframe for detection depends on the drug test:. Synthetic Marijuana , also known as K2 or Spice, are man-made chemicals that are sprayed on dried plants to be smoked or sold as liquids to be vaporized.
The results of drug tests for Synthetic Marijuana greatly depend on how frequently the user inhales the drug. Opioids are a class of drugs that include Fentanyl , Heroin , and pain relievers such as Oxycodone , Hydrocodone , Codeine , and Morphine. The misuse of prescription Opioids and Heroin affects 2 million Americans each year and is steadily increasing. Living in the midst of an Opioid epidemic may require employers or judges to test people for drugs.
The timeframe for detection depends on the specific drug, the frequency and quantity of use, metabolism, and body fat. Make a Call Benzodiazepines are sedatives that are commonly prescribed for anxiety or insomnia. The number of adults misusing these drugs is increasing, with the largest group of people misusing being ages 50 to Common Benzodiazepines include Valium , Xanax , and Klonopin.
Benzodiazepines usually stay in your system for 2 to 7 days if being detected by a urine test but can be detected for longer if the use is repeated. Some Hallucinogens, like PCP and Ketamine , are man-made chemicals while others such as Psilocybin commonly called magic mushrooms are grown as plants and then consumed. Most of these drugs will be out of your system in a few days, but similar to other drugs, they can be found in hair follicles up to 90 days after use. Sixteen million American adults are prescribed Stimulants that are meant to treat attention-deficit hyperactivity disorder and narcolepsy.
Unfortunately, some people misuse prescription medications or use illicit drugs such as Cocaine or Methamphetamine. Barbiturates are drugs mainly used to treat insomnia and seizures disorders. They are not as commonly prescribed as they used to be because of better alternatives available today. However, the number of people abusing Barbiturates is on the rise, giving the user a high that makes them feel drowsy and intoxicated.
There are several factors that determine how long Barbiturates will stay in your system. First is if the drug is short acting or intermediate acting. Second is how much and how often the drug is taken, and third is the individuals body weight, hydration levels, metabolism, food intake, and sex. Alcohol is a Central Nervous System Depressant, and although it is legal for people over 21 in America, it is commonly abused and causes 88, deaths each year. Most standard drug tests do not include alcohol, but there are tests to confirm alcohol abstinence if need be.
There are hundreds of products that claim to help people pass drug tests, such as synthetic urine and detoxing cleanses, but the only guaranteed way to pass a test is to abstain from using drugs.
