When ingested or smoked, it produces euphoric effects. Users have impairment of short term memory and THC use slows learning. Also, it may cause transient episodes of confusion, anxiety, or even frank toxic delirium. Long term, relatively heavy use may be associated with behavioral disorders. Elevated levels of urinary metabolites are found within hours of exposure and remain detectable for 3-10 days after smoking.
Cocaine induces euphoria, confidence and a sense of increased energy in the user.
These psychological effects are accompanied by increased heart rate, dilation of the pupils, fever, tremors, and sweating. This test is based on the competition for the limited antibodies between immobilized drug conjugate on the membrane and drug or drug metabolite which may be present in the urine being tested. In the test procedure, a sample of urine is placed in the sample well and is allowed to migrate upward. When the drug is present in the urine sample, it competes with drug conjugates which are immobilized on the membrane for the limited amount of antibodies present in the dye-antibody conjugate. In addition to the Test line that may appear in the Test window, a Control line is added in the Control window to confirm the viability of the test.
