I was a little off - sedative-hyptnotics like benzos and barbiturates can also kill you through withdrawal. http://en.wikipedia.org/wiki/Delirium_tremens http://en.wikipedia.org/wiki/Delirium_tremens "Withdrawal from sedative-hypnotics other than alcohol, such as benzodiazepines or barbiturates can also result in seizures, delirium tremens and death if not properly managed. Withdrawal from other drugs which are not sedative-hypnotics such as opiods, marijuana, cocaine etc do not have major medical complications and withdrawal is therefore not life threatening."
