This is a terrible article. It is sensationalist. It is undated. When it finally gets round to quoting a scientist, the quote undermines the certainty in the headline: “[cannabis] may offer a new road to therapy against lung cancer”. It is full of references to absent footnotes.

Much of the text is lifted directly from a “source” link at the bottom. That document is also full of references to absent footnotes.

This isn't even up to the low standards of the Daily Mail.
