Considering Choices that Affect How Long a Drug Stays in Your System

Drugs respond to your physical condition and the choices you make. For example, it takes longer if you already have other drugs or alcohol in your system. Your use of a particular drug and the amount you use makes a big difference. In addition, how often you use a drug can affect your tolerance for it.

Whether you engage in physical activity daily and drink enough water can significantly impact drug processing time. Of course, medical conditions that affect your kidneys or liver can make everything take longer. So a simple question turns out to have a complicated answer. A decision to use drugs can make you worry about addiction, especially when you want to beat a drug test. There are different types of test and testing methods: urine drug test, saliva test(oral fluid), hair drug testing, blood tests, etc. Drug screens only show non-negative test results and test a person’s urine for elevated levels of specific drug metabolites.

Understanding Why Age, Gender and Body Weight Matter

Blood flow to the liver where drugs get processed reduces by about 35 percent with age, and the liver gets smaller too. In addition, metabolizing drugs tend to take longer in women than men, and obesity can also influence the rate.

Staying Fit and Drinking Water

An upcoming drug test can give you one reason to wonder how long do drugs stay in your system. However, getting enough rest and sleep can help remove your concerns. In addition, eating a healthy diet and drinking six 8-ounce glasses of water daily help keep you fit and well-hydrated. Plenty of water gives your liver time to process alcohol so you can eliminate it. In addition, when you exercise for fitness, it increases your breathing rate and puts more oxygen in your bloodstream. Both help your liver metabolize the drugs in your system.

Making the Job Harder or Easier

It probably seems obvious that the harder you make it for the organ that processes drugs to do its job, the longer it takes. Your illicit drug of choice(benzodiazepines, barbiturates, opiates, codeine, fentanyl, oxycodone, phencyclidine(pcp), propoxyphene, adderall, etc.) and the amount you use can determine how long your liver needs to get rid of the substances. However, Chronic users’ bodies may get used to the presence of drug you use regularly and build up a tolerance for it. When that happens, it can make a drug stay with you longer than it may for someone who uses it once in a while. The greater the amount of a drug you use produces a similarly greater time to metabolize it.

Checking on Cause and Effect
