delta-9-tetrahydrocannabinol – (THC, Mary Jane, weed, dope, pot, etc.) is a dry, shredded green and brown mix of leaves, flowers, stems, and seeds from the hemp plant Cannabis. This substance is one of the most commonly used illicit drugs in the United States. Marijuana has become legal for recreational purposes in some states (Washington, Oregon, Colorado, and Alaska) and even more states for medical use. While some states have legalized marijuana, the substance remains illegal at the federal level. Employers can still test for this drug. Marijuana is used in multiples forms. This substance is smoked in hand-rolled cigarettes (joints), in water pipes (bongs), and also in emptied cigars refilled with marijuana (blunts). THC is consumed through edibles as well.
The short terms effects of use include, but are not limited to, altered perception, changes in mood, impaired body movement, lack of concentration, increased appetite, and impaired memory. THC also has the capability to affect users in the long-term. Brain development is impacted by use of marijuana in terms of reducing thinking, memory, and learning functions. The drug is also linked to temporary hallucinations, paranoia, depression, anxiety, and suicidal thoughts in teenagers.
One of the most standard drug testing panel is a 10-panel urine drug screen. This test can detect THC going back about 1-3 days with occasional use and about 30 days with habitual use. AMC also offers hair follicle testing that can detect use going back 60-90 days.
