A British study by Oxford researchers found that people taking tranquilizers such as Valium were five times as likely to have a serious road accident as other people.

“There is good evidence of physical addiction with Valium . . . A lot of people don’t know that Valium, Darvon, and codeine are addictive, and these are the [drugs] now being far too widely prescribed.”​—Dr. Sidney Wolfe, Public Citizens Health Group.

‘Valium withdrawal is more intense than heroin withdrawal.’​—Testimony by a doctor before U.S. Senate.
