The Portman Group has slammed two more products it claims will encourage irresponsible drinking.
The watchdog has argued that a pub breathalyser and a new dietary supplement that says it can stave off a hangover are both sending out the wrong messages.
The breath test machine will be available in pubs from July and will tell drinkers whether they are "OK" to drive, "high" or "unsafe to drive".
The Portman Group spokesman Jim Minton said: "Our message is simple - don't drink and drive. If you do want to drink when you go out make sure you designate a non-drinking driver who can get you home safely."
Meanwhile RU-21, a US dietary supplement, hits UK shelves in June and has been hailed by some websites in the US as a miracle cure for a heavy night.
David Poley, director of policy and good practice at The Portman Group, said: "It sends the wrong message to the consumer and can encourage irresponsible drinking."
