The most common method of drug testing in this country for narcotics, marijuana, and illicit substances is a urinalysis. Marijuana has been known to stay in one’s system for days or even weeks in high enough amounts to produce a positive urinalysis. The interesting thing here is that a positive drug test may therefore mean that the person is not under the influence of marijuana currently, and hasn’t been under it for days.If you’re interested and want to learn more about them, visit Buy Weed Online.
Medical marijuana is legal now in 15 states and commonly being utilized to alleviate problems from debilitating medical conditions such as glaucoma, nausea, vomiting, spasms, and pain.

Certain states, such as Arizona, have the ability to fire an employee if they test positive for marijuana while on the job and their job performance is being affected. But what methods are actually valid to know if someone is actively using? That would be a blood test, and the explanation is below.
What is being tested with a marijuana drug test? It is not actually THC, also known as tetra-hydro-cannabinol, which is a psychoactive component of marijuana.
What’s being tested for is one of the non-psychoactive cannabinoid metabolites called THC-COOH. This metabolite is produced by the liver, and is indicative of substantial metabolic degradation having already taken place. There is no correlation between a positive test and a current state of marijuana intoxication.
Unfortunately, this means urine tests are incapable of distinguishing between weekend use, regular use, or on-the-job impairment. So if you are on medicinal marijuana, working, and you undergo a urine drug test at work the result may be positive for “marijuana”. However, what’s being tested is the inactive metabolite which is not indicative of current real time use.
Blood testing for marijuana is the most accurate test available, as it measures the actual presence of THC in the bloodstream. It actually detects the current presence of the psychoactive component in the blood. After using medical marijuana, a blood test will register positive for a few hours. In the first 10 minutes of smoking marijuana, THC levels peak sharply and then drop off dramatically over the next few hours.
