How long do drugs of abuse stay in the human boday, for example Marijuana?
Dear mrvlsmrv, well i have a drug test for probation on the 29th the last time I smoked was on the 6th at 1am, and that was the second time in the past 3 days and those three days was the first time for a at least a month...then once before that like 2 months...Just looking for some confidence...the saliva test i take is sent to a lab...I should be good right? absolutely right?
Response, so you had some pot like a week ago and you are hoping you will come clean on a saliva drug test here in about two weeks from now, not to shink your confidence, but there's just NO guarantee of that. I'm actually surprised that your probation officer is using a saliva drug test instead of a urine drug test. Consider yourself very lucky, because if you were in my area, they would do a urine drug test and those go back 30 days on marijuana, sometimes longer for chronic users of pot. If what you are telling me is true, you are borderline, just make sure you do not smoke any more grass ever if you want to pass at last in two weeks or God forbidden it takes longer to work out of your system. Keep in mind, drugs are detected within your body mass per most instant and rapid drug test of most kinds. THC (marijuana): (THC) Tetrahydrocannibinol (THC) is an active component in marijuana. Marijuana, a hallucinogen, is oftten ingested by smoking (i.e. smoking a joint), but it may also be eaten. Marijuana may impair learning and coordination abilities. Marijuana is most commonly the drug of choice among teenagers and young adults. The hallucinogenic effect of Marijuana can lead to irrational behavior, disorientation, and paranoia. Low concentrations of THC persists in urine at a detectable concentration for many days after smoking pot in a pipe or joints, etc... Marijuana is the most common recreational drug of abuse.
  • Single Use: 14 days in a Urine Drug Test
  • Chronic Use: Up to 30 days, sometime longer
up to 90 days in Hair 2 days in Blood
Fact - We had a truck driver come through our office in the spring of 2008, the first time in, he said he hadden smoked pot in 2-3 weeks and that when he did, that was the first time he had done pot in 12-14 years. Well he was postive on the DOT required urine drug test our first try. He came back a week later per his DOT certified counselor and tested positive again. He bought some rapid drug test for himself and continually tested at home. He came back in 7 to 10 days and was postive again, this time it had been over the normal 30 days for urine metabolites to clear up. He said and I quote "man that must have been some really good stuff for me to still be positive after 30 days". Keep in mind, he hadden fooled with pot in 12-14 years and all of a sudden decided to try a joint or two with some so called freinds, this is an over the road truck driver, good thing he was self employed, because he could have been terminated by most employers. To shorten the true story of it all is, this John Doe did not come clean for nearly two months, he had to outsource someone to drive his truck to keep his customers during his trial of smoking pot and got caught up in a random drug test.
