189
Q

Controlled Substances Act– Schedule 1

A

The drug has a high potential for abuse

There is no currently accepted medical use in treatment in the US

Lack of accepted safety for use of the drug under medical supervision

Examples:
LSD
Marijuana
Methaqualone (Quaaludes)

190
Q

Controlled Substances Act– Schedule II

A

The drug has a high potential for abuse

The drug has a currently accepted medical use with severe restrictions

Abuse of the drug may lead to severe psychological or physical dependence

Examples:
Morphine
PCP
Cocaine
Methadone
Methamphetamine

191
Q

Controlled Substances Act– Schedule III

A

The drug has less potential for abuse than the drugs in Schedule 1 and II

The drug has a currently accepted medical use in the US

Abuse of the drug may lead to moderate or low physical dependence or high psychological dependence

Examples:
Anabolic steroids
Codeine/Hydrocodone with aspirin or Tylenol
Some barbiturates

192
Q

A

The drug or other substance has a low potential for abuse compared to drugs in Schedule III

194
Q

Two steps to identification of drugs with the forensic setting

A

Screening tests
Confirmation tests

195
Q

Screening tests

A

Non-specific, preliminary

Used to reduce possibilities of identification to a smaller number of substances

196
Q

Confirmation tests

A

Specific

Usually, a single test which will prove the chemical composition of the substance in question

197
Q

Screening test– Colorimetric tests

A

Five primary tests:

Marquis
Dillie-Koppanyi
Duquenois-Levine (plus solutions)
Van Urk
Scott Test (plus solutions)

198
Q

Marquis

A

Turns purple in the presence of opium derivatives

Turns orange-brown in the presence of amphetamines and methamphetamines

199
Q

Dillie-Koppanyi

A

Turns violet blue in the presence of barbituartes

200
Q

Duquenois-Levine

A

Turns purple in the presence of THC

201
Q

Van Urk

A

Turns blue in the presence of LSD

202
Q

Scott Test

A

Turns blue, pink, and then blue again in the presence of cocaine

203
Q

Screening tests– Microcrystalline Tests

A

A specific test which can help identify certain chemicals

A reactant is added which creates specific crystal formations, specific to the drug in question

204
Q

Screening tests– Chromatography

A

Thin-Layer Chromatography (TLC) or Gas Chromatography (GC) separates drugs from their diluents for a tentative identification

205
Q

What is chromatography usually run alongside?

A

Colorimetric screening tests and/or microcrystalline tests

206
Q

Confirmation tests– Spectrophotometry

A

Using the Ultraviolet (UV) or Infrared (IR) regions, the absorption of light by drugs can be graphed and pinpointed to a specific drug

UV is useful for identifying the probable identity and exclude other drugs

IR can specifically identify a substance, but there must be as pure of a composition as possible

207
Q

Confirmation tests– GC/MS

A

Combines the power of gas chromatography with the abilities of a mass spectrometer (GC/MS)

With few exceptions, no two substances fragment in the same fashion; therefore, it serves as a “fingerprint” of a chemical substance
