Drug - Answer - Any substance that enters the human boxy and can change either the
function or structure of the human organism. This includes such items as foods,
vitamins, nutrients, minerals and the like.
Psychoactive Drug - Answer - A chemical substance that not only can change the
function and structure of the body, but also changes one's thinking, feelings,
perceptions and behavior. These changes are the result of the drug's action on the
human brain.
Depressant - Answer - Psychoactive drugs that slow down central nervous system
function, relax or tranquilize the person, and may produce sleep.
Narcotics - Answer - Psychoactive drugs - powerful painkillers, analgesics that also
produce pleasurable feelings and generally induce sleep.
derived from naturally occurring substances or manufactured synthetically; cause
sedation and euphoria by causing depression of CNS; used to medically relieve pain,
suppress cough and control diarrhea
overdose can cause death by respiratory depression
can cause physical/psychological dependence; impairs ability to drive; damage
developing fetus; linked with the spread of AIDS due to the use of needles
Stimulants - Answer - Psychoactive drugs - chemical substances that generally speed
up central nervous system function, resulting in alertness and excitability.
Hallucinogens - Answer - Psychoactive drugs - also called mind expanders or
psychedelics, these drugs affect a person's perception, awareness and emotions, and
can cause hallucinations as well as misinterpretations of reality.
Inhalants - Answer - Psychoactive drugs - volatile non drug chemical solvents that have
drug-like effects when inhaled. It includes commercial solvents (gasoline, toluene,
acetone, carbon tetrachloride), aerosols (freon, amyl nitrite, butyl nitrite), and
anesthetics (chloroform, ether and nitrous oxide).
Addiction - Answer - A chronic, progressive, relapsing disorder characterized by
compulsive use of one or more substances that results in physical, psychological, or
social harm to the individual and continued use of the substance or substances despite
this harm
Alcoholism - Answer - A primary, chronic disease with genetic, psychosocial, and
environmental factors influencing its development and manifestations. It is often
,progressive and fatal. It is characterized by impaired control over drinking,
preoccupation with the drug alcohol, use of alcohol despite adverse consequences, and
distortions in thinking, most noticeable denial. Each of these symptoms may be
continuous or periodic.
Abstinence - Answer - Refraining from the use of alcohol or other drugs
Drug Use - Answer - The use or consumption of a drug within some socially prescribed
or ritualistic context
Drug Misuse - Answer - The unintentional or inappropriate use of prescribed or non-
prescribed drugs resulting in the impaired physical, mental, emotional or social well-
being of the individual
Drug Abuse - Answer - The deliberate use of chemical substance for reasons other than
their intended medical purposes which result in any degree of physical, mental,
emotional or social impairment of the user, user's family, or society in general. It
involves using illegal as well as legal, 'recreational' drugs that lead to problems.
Drug Dependence - Answer - Psychological and/or physical need for a drug,
characterized by compulsive use, tolerance to the drug, and physical dependence
manifest by withdrawal syndrome. Since some drugs do not show identifiable signs of
withdrawal (e.g. marijuana), or if the signs of withdrawal are often misinterpreted as
something else (e.g. cocaine, stimulants), a drug can be viewed as creating
dependence if it produces euphoria in the user, and if as a result of that euphoria, it
creates a pattern of self-reinforced use.
Tolerance - Answer - A state of progressively decreasing responsiveness to a drug's
effects. In other words, a condition that requires the user to take more and more of a
drug to get the same, desired effect.
Physical Dependence - Answer - A state in which the presence of the drug is required
for the user to function normally. The body has adapted to the presence of the drug and
the body views this as normal and necessary.
Withdrawal - Answer - Drastic and characteristic changes in physical functioning and
behavior (insomnia, tremors, nausea, vomiting, cramps, elevation of heart rate and
blood pressure, convulsions, anxiety, psychological depression) due to over-excitation
of the nervous system. These effects are observed or experienced when the user stops
taking, or the use of a drug is significantly decreased (in which physical dependence
upon the drug has developed). There is a craving for the drug when one is abstinent,
and these symptoms are relieved when the drug is again taken. Also referred to as the
Abstinence Syndrome or Withdrawal Syndrome.
Relapse - Answer - The return to substance use after a period of abstinence.
, Routes of Administration - Answer - This refers to the method a drug is taken; has a
direct impact on the intensity and speed in which a drug has its effect.
Oral - Answer - A drug is taken into the mouth, where it passes into the stomach. In the
stomach, absorption begins, with the process continuing in the small intestines. Once
absorbed into the bloodstream, the drug makes its way to all body parts. Drugs taken in
this way generally take 20 to 30 minutes to have their effect. Some of the drug's
effectiveness is lost by this route of administration.
Inhalation - Answer - A drug is inhaled (by smoking) directly into the lung. In the lung,
the alveoli (air sacs) absorb the drug and move into the capillary system in the lungs.
From there the drug passes into the heart and then to the brain. Drugs taken in this way
generally take only 7 seconds to have their effect.
Intravenous - Answer - A drug is injected directly into a vein, where it travels to the
lungs, heart and brain. No other absorption is required. Drugs taken in this way take
approximately 14 seconds to have their effects.
Intranasal - Answer - A drug is inhaled into the nasal cavity, where it is absorbed in the
mucous lining of the cavity. It is then absorbed by the capillary system in the nose,
travels through the veins, then to the lungs, heart and brain. Drugs taken in this way
take from one to three minutes to have their effect.
Instillation - Answer - A drug is absorbed directly through the skin, where it is eventually
reaches the bloodstream. The skin is designed to prevent such absorption, but a few
drugs, most notable LSD, are absolute enter the system in this way. Drugs absorbed in
this way may take up to 60 minutes to have their effect.
Drug Dose - Answer - Refers to the quantity or amount of a drug that is taken at any
particular time. The greater the dose, the greater the drug effect.
The Threshold Dose - Answer - Minimal dose; refers to the smallest amount of a given
drug which is capable of producing some detectable response.
The Median Effective Dose - Answer - Describes the dose required to proceed a
specific response in 50% of test subjects
The Lethal Dose - Answer - Is that dose which would result in death for the user, while
the lethal dose 50%, or the LD-50 is the level of use that would kill 50% of those who
took that amount. The potential danger of a drug is measured by its LD-50.
Half-Life - Answer - An indication of the time required for half of the dosage of a drug
taken to leave the body.
Drug Effects - Answer - When drugs are taken in combination, the drug effects can
result in unexpected or even dangerous chemical interactions inside the body. One drug
