How long do drugs stay in your system? This is a question that many people may want an answer to, especially before facing a drug test for an employer. How long drug stay in your system depends on the type of drugs and certain personal characteristics.

The person's age, weight, and health affect how long drugs stay in your system. The person's stress level and how much or how often the drug was taken affects how long it is detectable by drug testing.

Drugs that are detectable by urine tests for about eight hours after use include LSD and psilocybin, commonly referred to as mushrooms or shrooms. Methamphetamine, GHB, Ecstasy, nicotine, amphetamines, oxycodone, heroin, codeine, morphine, and opiates are examples of drugs that typically stay in a person's system for about two days.

Marijuana and hash can stay in the person's system and be detectable by urine tests for up to five weeks. Benxodiazepines such as Valium and Xanax can stay in the system for up to six weeks.

Alcohol usually stays in the system for six to ten hours. PCP, also known as angel dust, can be in the system for up to eight days. Breathalyzer testing is commonly used by law enforcement to detect alcohol on a person's breath.

Since a percentage of alcohol consumed is expelled in the breath, this method is accurate and not easily fooled like many myths claim. The only popular myth that has any validity is that mouthwash can affect breathalyzer results. However, mouthwash will raise the alcohol measurement of the breatalyzer test results.

Hair testing is another type of drug test. Most hair tests can indicate which drugs have been consumed in the last ninety days.

Blood tests are another type of drug testing, but they are not often used since they are more expensive. False positives can occur due to some prescription medications.

Prescription drugs vary greatly by how long they stay in a person's system. A measurement of the drug's half-life is often used to describe how long the prescription drug stays in the system. The drug's half-life is how long it takes for the drug concentration to be half of its original potency in the body.
