Hair drug test kits detect the presence of various illicit substances in an individual's hair. These kits typically analyze the hair for the metabolites of the substances, which are the byproducts of the body's breakdown of the drugs. Here are some common drugs and their metabolites that can be detected in hair using a hair drug test kit:
1. **Cocaine**: Benzoylecgonine and ecgonine methyl ester
2. **Marijuana** (Cannabis): THC (tetrahydrocannabinol), THCA (tetrahydrocannabinolic acid), and CBN (cannabinol)
3. **Opiates**: Morphine, codeine, and 6-monoacetylmorphine (6-MAM)
4. **Methamphetamine**: Methamphetamine and amphetamine
5. **Amphetamines**: Amphetamine and methamphetamine
6. **Ecstasy** (MDMA): Methylenedioxyamphetamine (MDA) and hydroxymethylenedioxyamphetamine (HMMA)
7. **PCP** (Phencyclidine): PCP and norphencyclidine
8. **LSD** (Lysergic acid diethylamide): Lysergic acid and 2-oxo-3-hydroxy-LSD
9. **Ketamine**: Norketamine and norketamine-glucuronide
10. **Barbiturates**: Phenobarbital, amobarbital, and butalbital
11. **Benzodiazepines**: Alprazolam, clonazepam, diazepam, and lorazepam
12. **Carboxyhemoglobin**: Can indicate cocaine or benzene exposure
**Detectable time frames**:
- Cocaine: 1-3 weeks
- Marijuana: 1-3 weeks
- Opiates: 1-2 weeks
- Methamphetamine: 4-6 weeks
- Amphetamines: 3-4 weeks
- Ecstasy: 1-3 weeks
- PCP: 1-2 weeks
- LSD: 1-2 days
- Ketamine: 1-3 weeks
- Barbiturates: 2-4 weeks
- Benzodiazepines: 2-4 weeks
**Important note**: The detectable time frames may vary depending on several factors, including the individual's hair growth rate, hair length, exposure level, and metabolic rate.
Hair drug test kits can provide a window into an individual's past substance use, which can be useful in a variety of contexts, such as employment screening, court cases, and substance abuse treatment programs.
