Clonazepam .. Can You Tell Me How Long The Drug

Clonazepam .. can you tell me how long the drug is detectable in a saliva screen??? Haven't ever taken one and I ingested a 1 mg pill and I am always on guard for drug use as a rehabilitating addict but I slipped and I don't want a individual slip up to devour what life I've built over my past year of sobriety id prefer it to be a reminder of what I have to lose and how easy it can happen all over again
