Morphine is the most abundant

Morphine is the most abundant opiate found in opium, the dried latex from unripe seedpods of Papaver somniferum (the opium poppy). Morphine was the first active ingredient purified from a plant source. It is one of at least fifty alkaloids of several different types present in opium, poppy straw concentrate, and other poppy derivatives. The primary source of morphine is chemical extraction from opium.
