Q

What is the Extraction/Sample Preparation for marijuana?

A

Marijuana samples were manicured and homogenized before being transferred to a 10 mL screw capped vial to which 1.0mL of extraction solution was added. Vortex the tube containing the extraction solution and the sample for 15 minutes to destroy glandular trichomes/plant tissue and allow soluble chemicals to be dissolved in the extraction solvent. Transfer the extract from the pipette into a micro centrifuge tube fitted with a filter and subject it to centrifugation for 15 minutes. Remove the filter and store at -20 degrees until GC/MS analysis.

Q

What is the analytical technique used to extract marijuana?

A

The GC/MS system consists of an Agilent Technology 7890A gas chromatograph interfaced to a 5975C VLDMSD mass Spectrometer. A 30-m DB-1 fused silica capillary column and 0.25mm OD,0.25μm film will be used to analyze the extract.

Q

What precautions must you take when using a GC/MS?

A

To ensure that the instrument is operating properly a QC sample will be injected after every ten test samples.

16
Q

What is heroin?

A

Heroin is a semisynthetic drug, produced from the morphine contained in the sap of the opium poppy.; Papaver somniferum.

17
Q

What are the natural derivatives from this opium poppy plant ?

A

morphine and codeine

18
Q

What is morphine?

A

Morphine is a powerful narcotic that produces psychological responses such as apathy and euphoria, and is highly addictive. Injection of morphine directly into the bloodstream was more effective in relieving pain, but increased the number of morphine addicts.

19
Q

What is codeine?

A

Codeine although it is less potent than morphine, codeine is one of the most potent cough suppressants known.

20
Q

What is the Heroin Production Process?

A

Heroin is derived from the opium poppy plant and involves adding two acetyl groups to the morphine molecule to make it easily penetrate the blood-brain barrier. The drug is usually a white powder with a bitter taste, but impurities or additives may cause variations in color.

21
Q

Why can heroin be directly injected into the bloodstream?

A

Heroin is less soluble in water than morphine, but more soluble in non-polar solvents. This means that it needs to be injected directly into the bloodstream to be effective, but once it passes through the blood-brain barrier, it can act quickly.

22
Q

Who synthesized heroin?

A

It is stated that heroin was originally synthesized by C.R. Alder Wright, an English chemist working at St. Mary’s Hospital Medical School in London, England in 1874.

23
Q

How is heroin administered?

A

Heroin is administered in several ways listed below:

  1. Snorting
  2. Smoking
  3. Subcutaneous Injection
  4. Intravenous Injection
24
Q

How did the Jamaican government and DEA find a way to resolve the heroine problem using heroine?

A

The heroin batch being trafficked (containing adulterating agents) can serve as tags and a profile of these agents can be made.

25
Q

How can adulterating agents help?

A

The profile of adulterating agents present can help law enforcement officers determine the location of the drug, allowing them to hold those responsible for its distribution and trafficking accountable. This would reduce the drug trafficking rate.

26
Q

What is adulteration?

A

Adulteration was defined as the introduction of a pharmacologically active substance to the illicit drug.

27
Q

What is an adulterating substance?

A

The adulterating substance may have a physiological effect resembling that of the active substance, thereby disguising the lower concentration of active substance that is present.

28
Q

What are diluents ?

A

Diluents were defined as substances without a pharmacological effect that were added to illicit drugs.

29
Q

Common adulterant which may be encountered in heroin samples:

A
  1. Paracetamol
  2. Griseofulvin
  3. Diazepam
  4. Phenobarbital
  5. Piracetam
  6. Methaqualone
  7. Procaine
  8. Barbital
  9. Ascorbic acid
  10. Salicylic acid
30
Q

Common diluents that may be encountered in heroin samples:

A
  1. Sucrose
  2. Glucose
  3. Lactose/maltose
  4. Mannitol
31
Q

How heroin is semi synthesized?

A

The most important details in this text are the steps taken to extract morphine from an empty 55-gallon oil drum. 30 gallons of water are added to the drum and brought to a boil. 10 to 15 kilograms of raw opium is added to the boiling water, while soil, leaves, twigs, and other non-soluble materials float in the solution. Slaked lime (calcium hydroxide) is then added to the solution, converting the water insoluble morphine into the water soluble calcium morphenate. Codeine and other alkaloids become part of the residual sediment ‘sludge’ that comes to rest on the bottom of the oil drum.

As the solution cools, the morphine solution is scooped from the drum and poured through a filter of some kind. Burlap rice sacks are often used as filters. Morphine hydrochloride is purified by boiling calcium morphenate, adding ammonium chloride, and filtering it through cloth filters. It is then dried in the sun and formed into small brick-sized blocks in a press and wrapped in paper or cloth. The bricks are then dried for transport to heroin processing laboratories.

32
Q

The process of making heroin?

A

The process of making heroin involves mixing crude base with hydrochloric acid to create heroin hydrochloride. Adulterants such as caffeine, quinine hydrochloride or strychnine hydrochloride are then added. The wet paste mixture is dried over a steam bath and crushed into coarse lumps, which are then sifted through a mesh sieve and packaged for sale. The process takes about eight hours and can be done by one person with minimal skill.

33
Q

What are the short term effects of heroin on the body?

A

Euphoria
A dry mouth
Warm, flushed skin
Arms and legs that feel heavy
Upset stomach and vomiting
Itching
A fuzzy brain
Switching in and out of drowsiness (this is often called being “on the nod”

34
Q

What can long term heroin use lead to?

A

Collapsed veins
Insomnia
Infections of your heart lining and valves
Skin infections like abscesses and cellulitis
A higher chance of getting HIV/AIDS, hepatitis B, and hepatitis C
Liver and kidney disease
Mental disorders
Lung diseases like pneumonia and tuberculosis
Menstrual problems and miscarriage
