& Answers for Quick Understanding
Define and describe Epidemiology. - Correct Answer ✔️✔️is the study (or
the science of the study) of the patterns, causes, and effects of health and disease
conditions in defined populations.
It is the cornerstone of public health, and informs policy decisions and evidence-
based medicine by identifying risk factors for disease and targets for preventive
medicine
Epidemiology: challenges to research substance use trends. - Correct Answer ✔
️✔️Underreporting and reluctance to disclose•Limited availability and
reporting of data on different aspects of illicit drug demand and supply-Lack of
data is particularly acute in Africa and parts of Asia•Difficulty accessing some
portions of populations•Variability in drug purity•Difficulty with standard
measurements, so quantity of use is often not captured for illicit
substances•Emergence of new drugs•Black markets are difficult to measure•Drug
,trafficking organizations continue to adapt their manufacturing strategies in order
to avoid detection
Chronic effect of long term use of stimulant - Correct Answer ✔️✔
️Dopamine receptors shut down due to the overstimulation of dopamine
stimulants and acute effects - Correct Answer ✔️✔️caffeine
nicotine
cocaine
amphetamine
methamphetamine
speeds up activity in CNS. Faster nerve activity, increased heart rate, high body
temp, blood pressure, feelings of exhilaration, heightened alertness
depressants and acute effects - Correct Answer ✔️✔️cannabis
alcohol
sedatives
,tranquilizers (drug meant for anxiety)
anxiolytics
opiates/opioides
slow down activity in CNS, slow nerve activity, muscle relaxation, lower alertness,
drowsiness, decrease heart breathing rate.
hallucinogens and acute effects - Correct Answer ✔️✔️LSD
psilocybin
mescaline
peyote
intensified sensation and synesthesia, illusions and delusions and hallucinations,
altered sense of time, impaired judgment and reasoning, bad trips
Caffeine - Correct Answer ✔️✔️Stimulant
antagonist
, adenosine
cannot overdose
Nicotine - Correct Answer ✔️✔️Stimulant
Agonist acetylcholine ~ mimics
releases dopamine GABA
Cocaine - Correct Answer ✔️✔️Stimulant
floods brain with dopamine then blocks the re-uptake of (agonist and antagonist)
of dopamine, serotonin,
overdose = hallucination/psychosis
Amphetamine - Correct Answer ✔️✔️Stimulant
releases dopamine, norepinephrine and serotonin
Methamphetamine - Correct Answer ✔️✔️Stimulant
How many neurotransmitters are involved with addicton? - Correct Answer ✔
️✔️8
