To know the effects of alcohol and drugs on the body and be aware of the on-the-job
problems substance abuse can cause.
Review the case studies or create others. Divide the workers into two groups to
discuss scenarios. Identify the primary ways substance abuse can affect performance.
Drugs and alcohol have many detrimental effects on the body, and increases the possibility of accidents
in the workplace.
Alcohol, a drug, is a central nervous system depressant. With moderate drinking a person may
- dulling of senses
- impairment of coordination
- impairment of reflexes
- impairment of memory
- impairment of judgment.
When alcohol is consumed in larger quantities over a long period of time, death may occur due to
depression of the parts of the brain that control breathing and heart rate. Alcohol in large amounts,
or over a long period of time, may cause damage to the:
Drugs, which include Marijuana, Cocaine, Crack Cocaine, Heroin, LSD (Lysergic Acid Diethylamide), PCP (Phencyclidine), and many others, can last for several months in the body. They can cause:
- decreased long and short term memory
- decreased concentration
- distorted senses
- impaired perception of time and space
- slowed reaction time
- temporary blindness
Substance Abuse and Job Performance:
Case Study 1
- Alcohol can affect job performance for up to 14 hours.
- The combination of alcohol and drugs multiplies their effects and increases the risk of injury and death.
- Drug and alcohol use increases the possibility of an on-the-job accident.
Joe drank beer and wine in high school and started using other drugs as a young adult. While working
on the Miller farm, he started taking speed (amphetamines) to get going in the morning. The drugs
interfered with Joe's ability to make safe judgments and caused a series of on-the-job injuries to himself
Case Study 2
Molly, a forklift operator, drank alcohol during her lunch hour. During a 16 hour shift, she drank on
two occasions and then went back to work. Molly knew she was "high," but felt that she could
work. Before the shift ended, Molly struck a barrier with the forklift and was thrown from the
vehicle. She lost work as a result of the injury.
After each case study, discuss the following points:
- The immediate cause of the incident and/or series of incidents.
- Contributing factors that led to the incident and/or series of incidents.
- Similar situation(s) that could result in illness or injury.
- How these situations could be prevented.
True or False
- Alcohol is a drug.
- Even with moderate drinking a person experiences impairments.
- Drugs can last several months in the body.
- Working under the influence of drugs and/or alcohol can cause a serious accident.
- The effects of alcohol can last up to 14 hours.
- Using both alcohol and drugs increases the problem and can lead to a serious accident.
- If you have a problem, tell someone who can help.
|1. Drinking alcohol will affect job performance.
|2. Job performance may be impaired up to 14 hours after drinking alcohol.
|3. The combination of drugs and alcohol has little to no effect on working.
|4. If a co-worker is affected by drugs/alcohol, it is not a problem.
|5. With moderate drinking a person may experience impairments in coordination, reflexes, judgment., and memory.
