DDT (Dichloro diphenyl trichloroethane) is a colourless, crystalline, tasteless and almost odourless organochloride known for its insecticidal properties. DDT is not derived from any plant rather it is prepared by the chemical reactions of some chemical compounds.
Opioids (opiates) are the analgesic drugs that are derived from latex of unripe fruits of poppy plant, Papaver somniferum. Similarly, cocaine and cannabinoids are the drugs derived from Erythroxylon coca (Coca plant) and Cannabis sativa (Hemp plant) respectively.
