Tory peer could be refused entry to US after cannabis revelation in the Times

Daniel Finkelstein may fall foul of legal anomaly despite using drug in state where it was allowed, says lawyer

A Conservative peer may have damaged his chances of being allowed back into the US after legally smoking cannabis in Colorado, a leading immigration lawyer has said.

Daniel Finkelstein wrote in the Times on Monday of how he smoked marijuana for the first time at a friend's house in the state, where buying limited quantities of the drug for recreational use has been allowed for almost a decade.
