Different Types of Drug Testing, Drug Detox Tips
In: News
30 May 2007The following chart gives approximate detection periods for each substance by test type. Data for urinalysis are reproduced from LabCorp’s . The ranges depend on amount and frequency of use, metabolic rate, body mass, age, overall health, and urine pH. For ease of use, the detection times of metabolites have been incorporated into each parent drug. For example, heroin and cocaine can only be detected for a few hours after use, but their metabolites can be detected for several days in urine. In this type of situation, we will report the detection times of the metabolites.
Drug Detection Periods
| Substance | Urine | Hair | Blood |
| Alcohol | 3-5 days via Ethyl Gluconoride (EtG) metabolite or 10-12 hours via traditional method | 12 hours | |
| Amphetamines (except meth) | 1 to 2 days | up to 90 days | 12 hours |
| Barbiturates (except phenobarbital) | 2 to 3 days | up to 90 days | 1 to 2 days |
| Benzodiazepines | Therapeutic use: 3 days. Chronic use (over one year): 4 to 6 weeks | up to 90 days | 6 to 48 hours |
| Cannabis |
|
up to 90 days | 2 days |
| Cocaine | 2 to 4 days | up to 90 days | 24 hours |
| Codeine | 2 days | up to 90 days | 12 hours |
| Cotinine | 2 to 4 days | up to 90 days | 2 to 4 days |
| Heroin | 2 days | up to 90 days | 6 hours |
| LSD | 2 to 24 hours | Up to 3 days | 0 to 3 hours |
| Methamphetamine | 1 to 2 days | up to 90 days | 24 hours |
| Morphine | 2 days | up to 90 days | 6 hours |
| Methadone | 3 days | Up to 30 days | 24 hours |
| PCP | 14 days; up to 30 days in chronic users | up to 90 days | 24 hours |
| Phenobarbital | 7 to 14 days | up to 90 days | 4 to 7 days |
* Oral fluid or saliva testing results for the most part mimic that of blood. The only exception is THC. Oral fluid will likely detect THC from ingestion up to a maximum period of 18–24 hours.
* Urine can not detect current drug use. It takes approximately 6–8 hrs. post-consumption for drug to be metabolized and excreted in urine. Similarly, hair requires two weeks, and sweat, seven days.

Some say that the main purpose of random school drug testing is not to catch kids using drugs, but to prevent them from ever using drugs, illegal or not. Once teenagers are using drugs it is much harder for them to break their addiction. Maybe it’s the issue of peer pressure, which is the greatest cause of kids trying drugs. If by testing the athletes or other school leaders, we can get them to say no to drugs, it will be easier for other kids to say no

The figures are at best an average over multiple testing methods; at worst they are highly inaccurate.

Its good to see such kind of information here.Are services or referrals offered to family members to ensure they understand drug addiction and the drug recovery process to help them support the recovering individual?

I smoked Marijuana occasionally (maybe every other day or so) for a few months, then I stopped for 2 and a half weeks and smoked a gram and then stopped again for 2 and a half weeks and took two bong rips and then stopped for two weeks and five days and was tested… Will I most likely pass or fail?
I Weight 180 I’m about 6′4 i’ve been excersizing every other day and even when i’m not “excersizing” i’m reasonabley active
