Introduction
• Four principal routes drugs enter the body
Oral
Injection
Inhalation
Absorption through the skin or membranes
Copyright © 2016 by Pearson Education, Inc. All Rights Reserved
Drugs, Society, and Criminal Justice, Fourth Edition Charles F. Levinthal
Oral Administration
• Ingesting a drug by mouth leads to it being digested and absorbed into the bloodstream via the intestine.
• Advantages
Oldest and easiest way of taking a drug
Long absorption
• Disadvantages
Slow absorption time
No immediate effect continued on next slide

Drugs, Society, and Criminal Justice, Fourth Edition Charles F. Levinthal
Oral Administration
• Natural barriers in the stomach, intestines, and blood-brain barrier require that the dose be elevated to allow for the fact that a portion of the drug will be lost.
Copyright © 2016 by Pearson Education, Inc. All Rights Reserved
Drugs, Society, and Criminal Justice, Fourth Edition Charles F. Levinthal
Injection: Intravenous
• Injecting a drug with syringe and needle, directly into the bloodstream ("mainlining")
• Advantages
Fastest means of injection
Large amount of control
• Disadvantages
Intravenous is irreversible.
Veins can collapse, develop blood clots
Copyright © 2016 by Pearson Education, Inc. All Rights Reserved
Drugs, Society, and Criminal Justice, Fourth Edition Charles F. Levinthal
Injection: Intramuscular
• Injecting a drug into a large muscle, which is absorbed into the bloodstream
• Advantages
Slower absorption time
Administered rapidly in emergency
• Disadvantages
Slower absorption than intravenous
Risk of piercing a vein by accident
Copyright © 2016 by Pearson Education, Inc. All Rights Reserved
Drugs, Society, and Criminal Justice, Fourth Edition Charles F. Levinthal
Injection: Subcutaneous
• Injecting a drug into tissue under skin (skin-popping)
• Advantages
Slowest absorption time of all
Steady absorption, control
• Disadvantages
Skin easily irritated
Risk of irritation
Only small amounts can be injected.
Copyright © 2016 by Pearson Education, Inc. All Rights Reserved
Drugs, Society, and Criminal Justice, Fourth Edition Charles F. Levinthal
Inhalation
• Breathing in vapors from a drug
• Advantages
Extremely fast absorption time
Travels from lungs to brain in five to eight seconds
• Disadvantages
Effect limited to time drug is inhaled.
Lung and throat irritation
Copyright © 2016 by Pearson Education, Inc. All Rights Reserved
Drugs, Society, and Criminal Justice, Fourth Edition Charles F. Levinthal
Absorption (Skin or Membranes)
• A drug is sniffed, snorted, chewed, used as a suppository, placed under tongue (sublingual), or used as a transdermal patch.
• Advantages
Quick absorption time
Enhances skin penetration
• Disadvantages
Irritation of skin or membranes

How Drugs Exit the Body
• Biotransformation
Metabolic action in the liver (chemical breakdown) leads to urinary excretion.
• Water-soluble
Action in the liver and kidneys leads to excretion in the urine.
Most common

How Drugs Exit the Body
• Less water-soluble
Action in the intestines leads to excretion through defecation.
Copyright © 2016 by Pearson Education, Inc. All Rights Reserved
Drugs, Society, and Criminal Justice, Fourth Edition Charles F. Levinthal
Factors Affecting Drugs Exiting the Body
• Quantity of the drug
The larger the quantity of the drug the faster the body tries to get rid of it, except alcohol which is constant.
• Presence of other drugs
• Age of the user
Over 40 years old, people eliminate drugs slower.
continued on next slide
Copyright © 2016 by Pearson Education, Inc. All Rights Reserved
Drugs, Society, and Criminal Justice, Fourth Edition Charles F. Levinthal
Factors Affecting Drugs Exiting the Body
• Drug's chemical properties lead to different exiting rates.
• Elimination half-life is the amount of time it takes for the drug in the bloodstream to decline to 50 percent of its original equilibrium level.
Copyright © 2016 by Pearson Education, Inc. All Rights Reserved
Drugs, Society, and Criminal Justice, Fourth Edition Charles F. Levinthal
Factors Determining the Behavioral Impact of Drugs
• Type of delivery route can optimize or place constraints on the effect of the drug.
Timing of administration
Interaction of two drugs administered close together
Repeat administration can diminish the effect
The user himself
Copyright © 2016 by Pearson Education, Inc. All Rights Reserved
Drugs, Society, and Criminal Justice, Fourth Edition Charles F. Levinthal
Timing
• Latency period
Drug is increasing, yet not yet detected.
• Latency of the drug is related to the absorption time of the drug.
• Effect of the drug will attain maximum strength while the concentration in the blood continues to rise.
Time release keeps therapeutic dose without toxic effects.
Copyright © 2016 by Pearson Education, Inc. All Rights Reserved
Drugs, Society, and Criminal Justice, Fourth Edition Charles F. Levinthal
Drug Interactions
• Two drugs in combination may produce an acute effect that is greater than the effect if administered separately.
• Additive effect adds the two effects of the drugs together.
• Hyperadditive effect is an acute effect in which the combined effect exceeds the sum of the two drugs is administered separately.
continued on next slide
Copyright © 2016 by Pearson Education, Inc. All Rights Reserved
Drugs, Society, and Criminal Justice, Fourth Edition Charles F. Levinthal
Drug Interactions
• Synergism
Any hyperadditive effect produced by a combination of two or more drugs
• Potentiation
The possibility that one drug might have no effect at all unless it is taken simultaneously with another
continued on next slide

Drugs, Society, and Criminal Justice, Fourth Edition Charles F. Levinthal
Drug Interactions
• Antagonistic
The acute effect of one drug is diminished to some degree when administered with another.
Copyright © 2016 by Pearson Education, Inc. All Rights Reserved
Drugs, Society, and Criminal Justice, Fourth Edition Charles F. Levinthal
Tolerance
• The capacity of a specific dose of a drug to have a gradually diminished effect on the user as the drug is taken repeatedly.
continued on next slide
Copyright © 2016 by Pearson Education, Inc. All Rights Reserved
Drugs, Society, and Criminal Justice, Fourth Edition Charles F. Levinthal
Tolerance
• Behavioral tolerance (conditional tolerance)
Tolerance is maximized when the drug- taking behavior occurs consistently in the same surroundings or under the same set of circumstances.

Cross-Tolerance
• The chronic use of one drug inducing a tolerance effect with regard to a second drug that has never been used before.
• Example
An alcoholic will already developed a tolerance for a barbiturate, or a barbiturate abuser will need a greater amount of anesthetic when undergoing surgery.

• Differences in enzyme levels
Ethnic background
Patterns of the drug taking behavior
Copyright © 2016 by Pearson Education, Inc. All Rights Reserved

• Physical symptoms suggest that there is a physical need for continued drug use.
• Withdrawal symptoms are often the opposite of the effects the drug had on the body.
Copyright © 2016 by Pearson Education, Inc. All Rights Reserved
Drugs, Society, and Criminal Justice, Fourth Edition Charles F. Levinthal
Psychological Dependence

Why Do People Take Drugs?
• Moral model of drug abuse
Drug-taking behavior is a matter of choice.
Not a biological defect, abuse is a psychological dysfunction; or due to sociological circumstances.
Attributed to personal inadequacies, overindulgence, a weakness of will, or other serious character flaw
Copyright © 2016 by Pearson Education, Inc. All Rights Reserved
Drugs, Society, and Criminal Justice, Fourth Edition Charles F. Levinthal
Biological Perspectives
• Biological theories focus primarily on genetic factors, physiological factors, and neurochemical systems in the brain.
Copyright © 2016 by Pearson Education, Inc. All Rights Reserved
Drugs, Society, and Criminal Justice, Fourth Edition Charles F. Levinthal
Genetic Factors
• Genetic research has advanced.
• Genetic factors and environmental factors may play an equal role (or genetics slightly more so) in drug use and drug abuse.
• Genes play role in determining risk level
Genome mapping

Neurochemical Systems in the Brain
• Research on dopamine and drug dependence may show why some people are more prone to becoming drug dependent.
• Example
One study found men with a lower concentration of dopamine were the ones feeling the most pleasure from taking the drug.

Psychological Perspectives on Drug Abuse
• Some psychoanalytical theorists focus on getting high as an expression of power or drug dependence as a means of coming to terms of an unconscious death.
• A poorly functioning ego can lead to a self-destructive lifestyle, while a healthy ego should promote self-care, self-protection, and self-esteem.
