Due to the interest in drug screening in this newsgroup,
I'd like to share the following information provided by a local
(USA) drug screening laboratory:

Amphetamines		24 - 48 hours
Barbituates		Short-Acting (i.g. secobarbital) 1 day
			Long-Acting (i.g. phenobarbital) 2-3 weeks
Benzodiazepines		3 Days
Cannabinoids		Acute dosage of 1-2 'joints'   2-3 days
