"The story on these is that they were sold in American pharmacies for years. They date from 1880-1937. In 1937, when the Marihuana Tax Act was passed, they were removed from pharmacy shelves. Don has collected hundreds of these. About 150 of them have pills or liquid or weird gooey residue. He's giving us samples of all of these, so that we can try to extract DNA from any surviving plant matter in there and find out what kind of Cannabis went into these medicines and where it came from," said Mowgli Holmes.
