The Poison Act of 1919 aimed to regulate and control the import, possession, and sale of poisons in India. It granted powers to state governments to license and regulate the possession for sale and sale of specified poisons. It also allowed the state to specify the classes of people who could be licensed, the maximum quantities that could be sold to individuals, and requirements to maintain sales registers and safely store poisons. The central government was empowered to regulate the import of poisons. The act defined lists of poisonous substances that fell under its purview, including substances like aconite, arsenic, digitalis, and chloroform.
