I've had cause today to send an e-mail off to Drugscope, who describe themselves as "the UK's leading independent centre of expertise on drugs". Eventually the e-mail arrived in the inbox of their press officer and she's now kindly got back to me. This time, however, the electronic log-jam wasn't the fault of our occasionally wonky e-mail system.
"Apologies," says the press officer. "Our emails sometimes get blocked because they contain the word 'drug'."
