9. Cultivation of Opium
The staff of the Opium Department measure the fields, using a tape, shown here. 
Note that the peasant is standing in the row between two fields. 
The fields are check-measured with staff drawn from other states and districts. 
Those peasants growing more than the allowable are struck off the Opium rolls for future production, and the excess Poppy is pulled up and destroyed.

13. Cultivation of Opium
After the petals fall from the poppy, the pod, which is about the size of a golf ball, is lanced, and the opium latex is exuded.  What you see here is one lancing, made with a special knife which has four blades about 1/16th inch apart, clearly visible in the photo.  Initially the latex is pink; later it changes to black

PH103.77

14. Poppies are lanced  in the afternoon and the latex is scraped off the next morning.  Peasants hope for calm, dry days during lancing season.  Rain  washes the latex off the pod, while friction of pods in the wind  rubs the  latex off .  Pods ripen (soften) at different times in the field.  Each pod can be lanced from 4 to 7 times.  The lancing takes a great deal of time and attention.
On the left, a woman scrapes the pod;  the close-up on the right shows the wide, curved blade with a rim of pink opium.  Several pods can be scraped before the opium is placed into a container.

15. Harvesting of Opium

PH103.77

16. Preparation of Opium
So many pods to cut and scrape! On the right, the opium collected is weighed on a daily basis before an officer of the Narcotics Dept. 
After the latex has been collected, all the peasants from an area take their opium to a weighment center.  On the left, courtesy of the Central Bureau of Narcotics, are the peasants waiting their turn for weighment;  their opium has been scraped into standard containers of known weight.  One-tenth of a hectare produces small amounts of latex.

17. CHEMICAL CONSTITUENTS
Opium contains about 25 alkaloids which are largely combined with Meconic acid.
The alkaloids of Opium are divided into two classes Pharmacologically i.e. Narcotic and Non-narcotic alkaloids and chemically as Phenanthrene derivatives and Benzyl Isoquinoline derivatives.
PH103.77

18. CHEMICAL CONSTITUENTS
The important active constituent of Opium is an alkaloid
Morphine which constitutes 8 to 17% of drug.
The other alkaloids of Opium are Codeine (2.5 to 3.5%)
Noscopine or Norcotine (5.5 to7.5%), Thebaine (1 to 2%) and
Papaverine 1%.
Indian variety contains maximum Codeine content as compared to several varieties of Opium.
PH103.77

19. USES
The active constituent of Opium responsible for its action is Morphine.
Opium is an Narcotic Analgesic, Hypnotic
It acts mainly on sensory nerve cells of Cerebrum.
It checks excessive peristalsis and contracts the pupil of eye.
Codeine (methyl morphine) is an Expectorant.
The syrup of Codeine phosphate is used in cough and Bronchitis.
