Who knows about drug detection times, just had an argument and need clarification???

[solidj55]

Just curious, me and a friend were talking about this the other night. We were arguing about detection lengths of time for certain drugs. He had to take a drug test not too long ago and was worried about passing it. He did of course but said he was just lucky. We were talking about things like GHB, Cocaine, Weed, Valium, and Lortabs. I told him Cocaine/Lortabs would be out of his system, as far as a urine test goes, witin 30 days give or take.
I told him the weed would be clear within 30-60days depending on how often/amount used. I was unsure about the GHB though.
He didnt agree and said the only reason he passed was because he used some over the counter bullshit to mask the drugs. Hell it had been about 8-10 months since he used Cocaine, Valium, and GHB. It had been about 3-4 months since he smoked week and at least 3-4 months since he used Lortabs.

Am I about right??? Also he tried to argue that they would test for ephedrine too lol. Just curious, I hate to be wrong in an argument.

I dont use this shit for obvious reasons but he does. I have researched this and this is what I came up with but he seems to think I am full of shit.

You are correct. Those OTC masking agents are bullshit.

Thanks bro I thought I was.

GBH and assorted benzodiazapenes (rufies, etc) have similar detection times, I believe. Depending on regularity of use, and amounts, I believe that detection time could be as short as 2-3 days, and as long as 2-3 weeks. Could be incorrect, but I seem to recall this from somewhere...

I know you are correct on the weed. The cocaine will be out of your system in about 5 day, sometimes 2 days.

Thanks for the replies, I told that asshole I was right lol.

[Use of gamma-hydroxybutyric acid (GHB) at rave parties and in date rape in France: myth of reality?]

Since many years gamma-hydroxybutyric acid (GHB) is presented as very popular in rave-parties and for bodybuilders. It seems to be a controversy between media coverage and the results of toxicological analysis done in high-level laboratories. In order to clarify this problem, we compiled the data of 6 laboratories. They used the same analytical method by GC/MS. Depending the laboratory, the limit of detection was 1-2 micrograms/mL and the limit of quantification was 2.5-5 micrograms/mL. Two labs where looking for GHB in each forensic case (100 and 150 cases a year). Others labs performed GHB analysis only on specific request (each 10 cases a year). Mean time between ingestion of GHB and blood/urine sampling was 12-48 h. Mean time between sampling and analysis was much higher (a few hours to a few month. All samples were stored at +4 degrees C. Only 3 cases were considered as positive (blood GHB: 165, 132 and 114 micrograms/mL, urine GHB: 7450 and 436 micrograms/mL) They were admitted in an hospital EU. Interpreting results remains very difficult because GHB is endogenous, present in blood and urine, and its half-life is very short. One has to report only "positive" GHB results when amounts are higher than 5 micrograms/mL in blood and 10 micrograms/mL in urine. Obviously, forensic toxicologists have to play a very important part in diagnosis of GHB intoxications and estimating its frequency. Actually, because the lack of data in France, it is not possible to answer the question asked in the title of this paper.
