'Smack' is a drug obtained from the:
a. latex of Papaver somniferum
b. leaves of Cannabis sativa
c. flowers of Dhatura
d. fruits of Erythroxylum coca
The answer is the option (a) latex of Papaver somniferum
Heroin, commonly referred to as smack, is a potent narcotic derived from the milky latex exuded by the opium poppy (Papaver somniferum). This latex transforms to yield opium, a substance teeming with morphine, which is then subjected to chemical modification, ultimately giving rise to the powerful drug known as heroin, or smack. The leaves of Cannabis sativa are utilized in the production of substances such as marijuana and hashish, but they play no role in the creation of smack. Similarly, the flowers of Dhatura, a plant rich in toxic alkaloids like atropine, are not involved in smack production. On the other hand, the leaves—not the fruits—of Erythroxylum coca are processed to produce cocaine, which is entirely unrelated to the synthesis of smack.
