What dose of clonazepalm leads to coma?

Too much: Benzodiazepines, of which Clonazepam (http://www.Drugs.Com/clonazepam.Html) is a member, can be sedating as well as addictive. One can get used to a small dose & gradually need/tolerate/handle larger doses that might cause a coma if taken the first time by someone who's never used this drug before. This dose can also be altered by amount of other drugs including alcohol in the system.
