Poison laboratory of the Soviet secret services

The Soviet Secret Services had a Poison Laboratory to create poisons. These poisons were used to harm people that the Secret Services thought were enemies of the Soviet Union. They created these poison chemicals in a laboratory so that they could find out how to make them as deadly as possible. Some of these poisons could make people very sick, or even kill them. The Soviet Union wanted to make sure that no one knew about the poisons, so they kept the laboratory a secret.
