Sensory Nerves Nerves that carry messages to the brain, from various part of the body,
including notably the sense organs (eyes, ears, etc.) Sensory nerves are also known as afferent
nerves.
Sinsemilla The unpollinated female cannabis plant, with a relatively high concentration of
THC.
Snorting One method of ingesting certain drugs. Snorting requires that the drug be in
powdered form. The user rapidly draws the drug up into the nostril, usually via a paper or glass
tube. Snorting is also known as insufflation.
Spygmomanometer A medical device used to measure blood pressure. It consist of an arm
or leg cuff with an air bag attached to a tube and a bulb for pumping air into the bag, and a
gauge for showing the amount of air pressure being pressed against the artery.
Standardized Conforming to a model in comparative applications.
Standardized Field Sobriety Test (SFST) There are 3 SFTSs, namely Horizontal Gaze
Nystagmus (HGN), Walk and Turn (WAT), and One Leg Stand (OLS). Based on a series of
controlled laboratory studies, scientifically validated clues of impairment have been identified
,for each of these 3 test. They are the only Standardized Field Sobriety Tests for which validated
clues have been identified.
Stethoscope A medical instrument used, for drug evaluation and classification purposes, to
listen to the sounds produced by blood passing through an artery.
Stroke A medical condition that occurs when a blood vessel that carries oxygen and
nutrients to the brain is either blocked by a clot or a burst and may cause observable signs and
symptoms which may mimic drug and alcohol impairment.
Sympathetic Nerve An autonomic nerve that commands the body to react in response to
excitement, stress, fear, etc. The brain uses sympathetic nerves to send "wake up calls" and
"fire alarms" to the muscles, tissues and organs.
Sympathomimetic Drugs Drugs that mimic the neurotransmitter associated with
sympathetic nerves. These drugs artificially cause the transmission of messages that produce
elevated blood pressure, dilated pupils, etc.
Synapse ( or Synaptic Gap) The gap or space between two neurons (nerve cells).
Synesthesia A sensory perception disorder, in which an input via one sense is perceived by
the brain as an input via another sense. An example of this would be a person "hearing" a
phone ring and "seeing" the sound as a flash of light. Synesthesia sometimes occurs with
person under the influence of hallucinogens.
, Systematic Done or acting according to a fixed plan or system; Methodical.
Systolic The highest value of blood pressure. The blood reaches its systolic value when the
heart is fully contracted (systole), and blood is sent surging into the arteries.
Tachycardia abnormally rapid heart rate
Tachypnea abnormally rapid rate of breathing
Tetrahydrocannabinol (THC) The principal psychoactive ingredient in drugs belonging to the
cannabis category.
Tolerance An adjustment of the drug user's body and brain to the repeated presence of a
drug. As tolerance develop, the user will experience diminishing psychoactive effects from the
same dose of the drug. As a result, the user typically will steadily increase the dose he/she
takes, in an effort to achieve the same psychoactive effect.
Tracks Scar tissue usually produced by repeated injection of drugs, via hypodermic needle,
along a segment of a vein.
Vein A blood vessel that carries blood back to the heart from the body tissues.
