Drug Addiction
- Effects are multiplied (enhanced)
- Expressed as 2+2=10
- Ex: alcohol and barbiturates

prevent the drug activation)
o Inhibition – the effects of one drug are eliminated or reduced by the presence of another drug
o Work at same receptor (mimic neurotransmitters)
o Ex: alcohol and antibiotics
Antagonistic effect
- Summation of effects of drugs taken concurrently
- Expressed as 1 + 1 = 2
- Ex. Aspirin and codeine (opioid agonist)
Additive effects
- Outcomes of self-directed or interpersonal violence
- Examples: Assaults, rapes, suicides, homicides

- A major community health problem
- Overall, fifth leading cause of death in the U.S
Unintentional injuries

Understand prevention and control of drug abuse Part 2
• Primary prevention
o Aims at those who have never used drugs
• Secondary prevention
o Aims at those who have used, but are not chronic abusers
• Tertiary prevention
o Aims at drug abuse treatment and aftercare, including relapse prevention

Aim to reduce either the supply or demand for drugs
Include a multitude of federal, state, and local agencies
Policies of drug prevention & control
- Drug users are found anywhere – occupations, income levels, social class, any age
- No one is immune to drug use which can lead to dependence
- Use us is not abuse
- Most users of any given substance don’t abuse or depend on it
- Abuse happens with legal drug as much as illegal drugs
- Misuse can lead to addiction
- Drug and alcohol abuse contribute to over 120,000 death in US a year
- Illegal drug use has huge financial burden on economy (181bil)
- Drug and alcohol is on of US most expensive community health issues
- Although drug use in US fallen 50% in last 20 years, the last 10 have shown increase of certain drugs by adolescents
General Principles of Drug Use
• Education
o Process of changing people’s health-directed behavior
o (e.g., speeding, aggressive driving, alcohol us, etc.)
• Automatic protection
o Modifying products or environments to reduce risk
• Regulation
o Enacting and enforcing laws to control behavior
• Litigation
o Seeking justice for injury through courts
Understand community approaches to injury prevention
o Leading type of unintentional injury death (e.g., 33,700 deaths in 2015) o Leading cause of nonfatal unintentional injury o Majority of those killed (2015) are Drivers Passengers Motorcycle riders Pedestrians Pedal cyclists
75% of the crashes occur within 25 miles of home at speeds less than 40 miles per hours
Teens are involved in 15% of all fatal crashes
Driver inexperience is the main reason for these vehicle crashes
Most motor crashes are a result of human error. The 5 most common reasons are:
• Excessive speed – 2/3rd of all crashes
• Aggressive driving – most are due to bad habit
• Driver distraction – caused by fatigue and sleepiness, cellular phones, passengers in the car, performing other task at the same time as driving, etc.
• Alcohol and other drugs use
• Nonuse of safety equipment – seat belts, front/side airbags
Motor Vehicle Crashes - Identify the type of unintentional injury and understand the summary
o Second leading cause of unintentional injury death
Unintentional ingestion of fatal doses of medicines and drugs
Consumption of toxic foods
o Exposure to toxic substances in the workplace or elsewhere
o Most cases occur in the home
o Ingestion is the most common route of poisoning exposure (77% of cases)
o Approximately 50% of cases involve nondrug substances, such as common household products (e.g., cosmetics, personal care items, cleaning solutions, foreign bodies, etc.)
Poisoning - Identify the type of unintentional injury and understand the summary
o Third leading cause of unintentional injury death
o Leading cause of injury-related ED visits
o Most cases occur in the home
o Disproportionately affect elders
Incidence
Mortality
Of those who are hospitalized, about 50% will not be alive a year later
In 2000, traumatic brain injury accounted for 46% of fatal falls
Cost
Fall-related injuries are among the most expensive health conditions
In 2000, $179 million were spent on fatal falls and $19 billion were spent on injuries from non-fatal falls
Falls - Identify the type of unintentional injury and understand the summary
