Drugs and the Law
Federal Controlled Substances Act
• Regulation of drugs in these ways:
– Registration
– Record Keeping
– Manufacturing Quotas
– Distribution Restrictions
– Dispensing Limits
– Import/Export abilities
Federal Controlled Substances Act
– Manner (i.e.. Security) of drug storage
– Reports from Manufacturer/Distributor to DEA
– Penalties
Federal Penalties

NYS and Federal Laws
(Possession)
• See hand-out
Drug Busts
(Step 1)
Search/Seizure/Legal Issues
How do we justify searches?
• Search Warrant: Probable Cause (4th)
• Warrentless Search:
– Plain Site Doctrine
– Consent
– Incident to arrest
Clues that a moving vehicle is
driven by a drug-impaired driver?
Signs While Moving
• Slow reaction
• Takes risks
• Vision Impairment
(weaving)
• Coordination problem
(weaving)
Car Stopped, Now Personal
Contact
Slurred Speech
Eye Analysis
Odors
Manner exiting vehicle
Pre Arrest Screening: Field Tests
• Psychophysical Tests:
– Test balance (Stand on 1 leg) (Walk and
Turn)
– Test Coordination (Touch nose)
– Information processing (Alphabet)
– Gaze Nystagmus (jerking of eyes, alcoholrelated)
Pre Arrest Screening: Field Tests
– Lack of convergence of eyes when pen
brought closer to face
– Check pupils with light
– Temperature check
– Blood Pressure Check
– Check Pulse rate
(See Hand-out)
Screening Failure
Search
Drugs found in car
7 people in car
Who is charged with Possession?
Forensic Science and the Law
• Science used to determine the qualitative
and quantitative nature of drug
• 70% of evidence in crime lab is drugrelated
Problem!
• Soooooooooooo many drugs!
Step 1
• Screening Tests (Color Tests)
– Marquis (Heroine,Morphine,-phetamines)
– Dillie-Koppanyi (Barbiturates)
– Duquenois-Levine (Marijuana)
– Van Urk (LSD)
– Scott (Cocaine)
Step 2
• Microcrystalline
Tests=
– Chemical added to
drug on slide to
produce a crystal
– Examine crystal size,
shape
Cocaine
Step 3
• Chromatography
– Thin-Layer, Gas Chromatography
– Tentative Identification+Purification
• Infrared Spectrophotometry (Need Pure)
• Mass Spectrometry (Chemical Fingerprint)
Marijuana Identification
Most evidence in fragment form:
Microscopic analysis
See “bear claw” hooks on
underside of leaf
Thin layer chromatography
Duquenois-Levine color test
Evidence Collection
• Bag and Tag
• Prevent loss and cross contamination
• Need airtight containers for solvents
