2. Narcotic Drug and Psychotropic
Substances
• Narcotic drug and Psychotropic substances(NDPS)
are all chemical that have an effect upon the body
and central nervous system (CNS), there use may
lead to physical and psychological dependence. Or
narcotic drugs are those substances, which give
relief from pain and induce sleep.
• Narcotics drug and Psychotropic substances(NDPS)
are of natural (opium alkaloids), semi-synthetics
(Heroin) and synthetic (Ecstasy) in nature.

4. CLASSIFICATION ACCORDING TO MODE OF ACTION
DEPRESSANTS Act on the central nervous system, which
slow down mental activity
STIMULANTS Act on the central nervous system, which
cause state of excitement.
HALLUCINOGENS Which produce hallucinations or illusions,
i.e. distortions of the senses.
CANNABIS Which in small amounts acts as a
depressant, but in larger doses has effects
similar to those of a hallucinogen.
OTHERS Steroids and solvents

5. Solvents
• In antiquity, human beings inhaled mind
altering gases like nitrous oxide and chloroform.
• A variety of common household products can be
used such as adhesives , aerosols spray, dry
cleaners and stains removers, cigarette lighter
fuel, typewriter correcting fluid, thinners, petrol,
paint and nail polish removers.

6. Drug Identification
The general principles that are followed when developing
an Analytical Scheme are as follows.
1. Visual examinations remain the first method employed.
2. Examinations must move from general to specific.
3.The schemes and processes must adhere to generally
accepted processes and tests accepted in the field.
4. Whenever possible perform at least one specific test.
5. Pay attention to the possibility that the sample may be
needed as an exhibit in court.
6.If there is not enough material for a complete series of
tests those that do not destroy the sample should be
performed first.
7. Use the tests that have the most telling results.

7. Drug Identification tests
1. Preliminary Test or Screening test:
• Physical appearance- colour, texture, smell etc
• Colour Test- Perform in chemical laboratory or
by the use of field test Kits.
2. Confirmatory Test:
• Chromatography- TLC
• Spectrophotometry- UV-Vis Spectrophotometer,
IR Spectrophotometer, FTIR
• Mass spectrometry
