Several sources claim that given the prolonged elimination
half-
life, tolerance does not develop. This is a lie, as the prolonged
half-
life pertains only to the "active metabolites" produced by the hydroxylation of Diazepam (Desmethyldiazepam, Oxazepam and Temazepam). The former is stored chiefly in fat, while the latter two are conjugated and rapidly excreted via kidney. Therefore, they aren't very "active". Diazepam itself carries a half-life of about 20 hours.
