Solution and Explanation
Step 1: Classify nicotine:
Nicotine is obtained from the tobacco plant, Nicotiana tabacum.
It is a nitrogen-containing, basic, plant-made compound. Such compounds are called alkaloids. So nicotine belongs to the class alkaloids.
Step 2: Another drug of the same class:
Morphine, obtained from the latex of the opium poppy Papaver somniferum, is an alkaloid.
Cocaine from the coca plant Erythroxylum coca is also an alkaloid.
Any one of these is a correct example.
Final Answer:
Nicotine is an alkaloid. Another drug of the same class is morphine (or cocaine).
