﻿ Employment and Preemployment Drug Testing

Drug Free is Healthy and Wealthy

Pre-employment Drug Screening

The pre-employment drug test is designed to eliminate substance-abusing job candidates from the pool of prospective employees. The mere fact that you require drug testing may discourage substance abusers from pursuing a position with your company. In addition, the Department of Transportation requires that employees in safety-sensitive positions be drug tested. By eliminating substance abusers from your company before they ever actually enter the workplace, you are protecting yourself from the dangers and hassles a drug-abusing employee presents.

Random Urine Drug Screen

Random drug screening is designed to discourage substance abuse among employees. This type of drug screening is most effective when accompanied by a clearly written drug abuse policy. Employees who know they may be tested for drugs are less likely to experiment with drugs of abuse, and employees with drug problems are more likely to seek help if they know their job is in jeopardy.

Implementing a Drug Testing Policy in your workplace

You can design a drug testing policy that satisfies not only your company's interest, but as well as the interest of your clients. Additionally, a drug testing program would also meet the requirements of various agencies such as the Bureau of Workers Compensation, etc.

In implementing a drug testing policy, suggestively, you can outline this by indicating the importance of drug testing, random drug testing, disciplinary action if positive for a drug test, etc. We would be glad to provide you with a pamphlet that describes further how to implement and enforce a drug testing policy.

Testing your employees or prospective employees for drugs is a simple process.  The following will explain the process such as specimen collection, reporting of results, etc.


1. Set-Up an account -  Please download the account set-up form, and submit to us via email at staydrugfree@toxassociates.com or mail to Toxassociates, Inc., 999 Bethel Rd., Columbus, OH 43214.

Click on this link to schedule an appointment.  Please bring with you a valid identification such as a driver's license, passport, current college id, or other government issued id's.  In addition, bring with you the drug testing form.


3.  Drug Testing Panel Options

You can choose an option for screening for drugs from hair and/or urine.  Hair is ideal for longer detection time for as long as the hair length, and for determining history of drug use if any.  Urine is ideal for recent drug use, within the past 1-3 days since most drugs can be detected in those time frames with marijuana being the longest, because it's fat soluble.


The most common option for drug screenings are a 5 Panel and 10 Panel Drugs of Abuse Screening.  Please choose the drugs that will conform to your policy, and either a 5 Panel or 10 Panel.


Benzodiazepines    Cocaine                                                  


Diacetylmorphine (Heroin)

 Drugs, Cause and Effect
& Detection Times



1. Alcohol

Alcohol is a general term that includes Methanol, Isopropanol, Ethylene Glycol, Ethanol, and many others.  Of interest is Ethanol that is found in alcoholic beverages such as beer, liquor, and wine.  These three types of alcoholic beverages will have different amounts or concentration of Ethanol.  It is notated by its proof, and in percentage it is half its proof.  For example, a Vodka with an 80 proof Ethanol will have a percentage of 40 % Ethanol.


Alcohol concentration may vary depending on body size and weight, age, consumption of food, and overall health. Additionally, elimination of alcohol in the body system decreases with age.  Interestingly, alcohol is highly drawn to water, and once absorbed in water it will be distributed evenly in all the fluids and tissues in the body, such that they contain equal concentration of alcohol. The effect of alcohol is determined by the total volume of water in the body. Thus, if two individuals having the same body compositions consumed the same amount of alcohol, the larger one will have less concentration of alcohol compared to the smaller individual. If the weights are similar, a physically fit (low body fat) compared to a heavier with more body fat, the alcohol will have a less significant effect. This is due to the fact that high body fat content will have reduced amounts of water in their body system, leading to less absorption of alcohol.

2. Barbiturates

The class of Barbiturates include Amobarbital, Butalbital, Pentobarbital, Secobarbital, Phenobarbital, and others.  The suffix "tal" is an indicator that is a Barbiturates.  These drugs are typically used as an anesthetic during surgery, and some such as Pentobarbital is used to induced coma in both humans and animals.  If the patient is terminal, the Pentobarbital concentration is monitored in blood until it is at 10 ng/ml or below.  The potential for abuse of Barbiturates still occurs, but not as often used as some of the more popular "get high" drugs such as Marijuana, Heroin, etc.  The detection times are between 2-4 days that can vary depending on the individual.


3. Benzodiazepines

These are another class of drugs with one the most popular is Valium (Diazepam) that is generally use for people who have trouble sleeping.  The Benzodiazepines class are also used for treatment as an anti-anxiety drug, traquillizer, depression, and others.  It has a rather longer detection times due to the fact that it is fat soluble, that are metabolized slowly. 


4. Cannabinoids (Marijuana)

This is probably the most popular drug of choice for getting "High", because it is easily obtainable, side effects are not as serious compare to Cocaine, or Heroin, and others.  Marijuana binds to the CB1 and CB2 receptors of the brain, and also affects the Hypothalamus part of the brain that controls hunger, thirst, and sex drives. 

The major active compound in Mariuana is called Delta-9-Tetrahydrocannabinol that is furter metabolized or broken down to 11-Hydroxy-Delta-9-THC, which is also active and finally broken down to 11-nor-Delta-9-THC, which is an inactive compound that is detected in urine in the drug screening process.


5. Cocaine

Cocaine is a stimulant drug with an effects of hyperactivity, loudness in voice volume, redness of the eyes, and others.  It has a very high potential for abuse, and addicition in that once a person is exposed to this drug it is difficult to stop using it.  It comes in many forms including "crack" Cocaine, "cut" or diluted with different substances such as lidocaine, acetaminophen, and others, or free base where the Cocaine compound is extracted in its almost pure form.  Cocaine is generally consumed through inhalation as it mixes readily with blood in a matter of a few seconds so that the "high" feeling is felt immediately.  Cocaine has a short detection period that vary between 1-3 days.
