  • Federal policies restricting marijuana research have made it difficult to study marijuana and produce cannabis-based drugs — but that isn’t stopping pharmaceutical companies from doing it.
  • Some are researching and developing drugs made with marijuana compounds in labs just north of the border. Others are growing the raw materials for their products in South America.
  • Although only a single cannabis-based drug is currently approved for use in the US, others are likely on their way.
