Spectroscopy is a way of identifying substances by using ... Matter Light Prisms All of the above. None of the above.

LEARNING OBJECTIVE Identify controlled substances using laboratory procedures such as spectroscopy.

spectrophotometry Spectrophotometry (aka spectroscopy) is a way to identify substances by exposing them to electromagnetic radiation (light)

spectrophotometry Light is given off when electrons jump from one place to another within an atom.

spectrophotometry Since each atom has a unique arrangement of electrons, each atom emits a unique mixture of different colored lights.

I expect you to refrain from talking or asking about personal experiences involving drugs.

AGENDA FOR TODAY DO NOW: spectroscopy short video. Spectroscopy lab – one packet for you and your learning partner. Do the lab // Put away supplies. Formative blog post. ----------------------------- Direct teach: drug “scheduling” laws. Article: why is marijuana a schedule I drug? Socratic seminar.

FORMATIVE BLOG POST: 1. Post a picture of one spectrum that you drew in your packet. 2. Write a short paragraph that explains what spectroscopy is AND why it is important. ***You can link to your learning partner’s blog post if you want.

Learning objective Explain the Drug Enforcement Administration / Controlled Substances Act drug scheduling system.

SUMMATIVE QUIZ NEXT CLASS! Concepts on the quiz: FDA drug categories (hallucinogens, depressants, stimulants, narcotics, anabolic steroids) Color change tests – who poisoned the chili? Chromatography – who stole my dog? Spectroscopy – today… DEA drug schedules (we will learn this next).

Drug Control Laws There are varying levels and penalties based on manufacture, distribution, possession, or use of a drug, as well as the drug’s weight, type, and concentration The Controlled Substances Act – the federal law that establishes five classifications of controlled dangerous substances on the basis of a drug’s potential abuse, potential for physical and psychological dependence, and medical value; the U.S. Attorney General has the authority to add, delete, or reschedule a drug as needed

Drug Control Laws (continued) Schedule I High potential for abuse and no currently accepted medical use in the U.S. Examples: heroin, marijuana, methaqualone, LSD

Drug Control Laws (continued) Schedule II High potential for abuse, currently accepted medical use with severe restrictions, potential for severe physiological and psychological dependence Examples: opium and its derivatives, cocaine, methadone, PCP, most amphetamine preparations, most barbiturate preparations, and dronabinol (the synthetic equivalent of marijuana, prescribed for medical use)

Drug Control Laws (continued) Schedule III Less potential for abuse, currently accepted medical use, potential for low to moderate physiological and high psychological dependence All barbiturates not included in Schedule II, such as codeine preparations and anabolic steroids

Drug Control Laws (continued) Schedule IV Low potential for abuse, current medical use, limited dependence related to Schedule III Examples: tranquilizers

Drug Control Laws (continued) Schedule V Low abuse, medical use, less potential for dependence than Schedule IV Non-narcotic medicinal ingredients and some opiate drug mixtures

Drug Control Laws (continued) Criminal Penalties Under the Act The most severe penalties are associated with Schedule I and II The Controlled Substance Act controls substances such as analogs and designer drugs that are chemically similar or related to controlled substances Regulates the manufacture and distribution of precursors which are the chemical compounds used by clandestine labs to synthesize drugs

Choose your own learning partners Choose your own learning partners! - 4 or less people per table - Sit at a regular table, not a lab table DO NOW: 2 minutes to discuss with your table A man is returning from Oklahoma by train. He was in a train car where smoking was allowed. If he had been in a non-smoking car, he would have died. WHY?

An Answer: The man used to be blind -- he's returning from an eye operation which restored his sight. He spent all his money on the operation, so when the train (which had no internal lighting) goes through a tunnel, he thinks he's gone blind again and decides to kill himself. But before he could do it, he saw the light of the cigarettes people were smoking and realized he could still see.
