Crystal Meth is NOT an anti-depressant. Crystal methamphetamine is a dangerous, very addictive substance. It is a drug classified as a synthetic stimulate or in other words, a man-made stimulant. Although users claim to experience euphoria, hyperactivity and a feeling of well-being etc. while using the drug, depression follows when the drug leaves the body's system or when the user is "coming down." Depression is actually one of the many negative long term effects that can result from using crystal methamphetamine.
About as long as it stays in your blood. "Spinal tap" drug tests, while feasible, are a myth. It's an overly invasive procedure for such a petty test when a blood or hair follicle test is as effective.
By crystal, i assume you mean methamphetamine. There is no way to escape the urine test for the day but, after the period of 24hours finishes, it will not be in your urine system anymore, only in your blood.*provided you dont smoke it someore.*drink lots of water.
Methamphetamine smoke is NOT detectable on blood urine or any other drug test if you are not inhaling this smoke. Second hand meth smoke. Please!
