Drug testing is a common procedure for employers, parents, and law enforcement. Some people are required to take blood tests as part of their jobs or court cases; others may be curious about their own drug use. It's important that you know how long different drugs stay in your system before taking a blood test so that you can avoid being falsely accused of drug use.
Yes, some drugs can be detected in an average blood test. The time it takes for a drug to leave your system depends on the type of drug, how much you take, and how often you use it. It also depends on whether or not the drug is fat soluble or water soluble; fat-soluble substances take longer to leave the body than water-soluble ones do because they're stored in fat cells rather than being excreted through urine or sweat (which are water-based).
There are hundreds of different drugs that could be tested for during an employment screening--but most employers only test for five common ones: marijuana/THC; amphetamines including methamphetamine; cocaine/crack; opiates such as heroin and morphine; PCP (phencyclidine).
There are several reasons a drug test could come back positive. If you've taken drugs recently, it may be detectable in your system for weeks or even months after the last time you used them.
Drugs that are metabolized quickly by the body (in as little as two days) will generally clear out of your system within a few hours after use, so if your blood test was taken at any point during this window of time and showed no traces of drugs, chances are good that you weren't actually using anything illegal at all.
Hair follicle tests can also be unreliable because they don't take into account how long it takes for different substances to show up on different types of hair: some will appear sooner than others depending on where they're located on our bodies!
Drugs can be detected in an average blood test for weeks or even months after the last time you used them.
Drugs such as cocaine, meth and heroin are often detectable for up to 30 days after use. This is because they have a high fat solubility and are stored in your body's fat cells, which takes longer than other organs (such as the liver) to flush out of your system. They also stay longer in hair follicles than other drugs do--so if you've been doing drugs for awhile, it may even show up on a hair follicle test!
