Poisoned Items: A Word Scramble

If Miss Eyelesbarrow is feeding the family arsenic in their curry, she's doing it for a reason.
Agatha Christie, 4.50 from Paddington

Christie was notorious for her accurate portrayal of poisons and their side effects. But not all chemicals in her books are used to cause a fatal poisoning. Some are used to drug the victim, produce alterations in behaviour, cause addiction, or serve as medication.

Below are seven Aga-grams which when unscrambled, reveal various items that have been poisoned in Christie's stories. Once you have deciphered the words, type them into the table.

As an additional challenge, can you name a story in which each of these appear?
