The only exceptions are THC (tetrahydrocannabinol) and benzodiazepines. Oral fluid will likely detect THC from ingestion up to a maximum period of 6–12 hours. This continues to cause difficulty in oral fluid detection of THC and benzodiazepines.
Long-acting benzodiazepines such as diazepam are not recommended for the elderly. [20] ... Diazepam was the most commonly detected benzodiazepine. [134] Legal status
[109] [112] This meta-analysis found that long-term use of benzodiazepines was associated with moderate to large adverse effects on all areas of cognition, with visuospatial memory being the most commonly detected impairment. Some of the other impairments reported were decreased IQ, visiomotor coordination, information processing, verbal ...
The benzodiazepines midazolam and temazepam were the two most common benzodiazepines utilized for date rape. [25] Benzodiazepines can be detected in urine through the use of drug tests administered by medical officials or sold at pharmacies and performed at home. Most tests will detect benzodiazepines for a maximum of 72 hours after it was taken.
Long-acting benzodiazepines with long-acting active metabolites, such as diazepam and chlordiazepoxide, are often prescribed for benzodiazepine or alcohol withdrawal as well as for anxiety if constant dose levels are required throughout the day. Shorter-acting benzodiazepines are often preferred for insomnia due to their lesser hangover effect.
In a Swedish (2003) study benzodiazepines were implicated in 39% of suicides by drug poisoning in the elderly 1992–1996. Nitrazepam and flunitrazepam accounted for 90% of benzodiazepine implicated suicides. In cases where benzodiazepines contributed to death, but were not the sole cause, drowning, typically in the bath, was a common method used.
Effects of long-term benzodiazepine use may include disinhibition, impaired concentration and memory, depression, [19] [20] as well as sexual dysfunction. [6] [21] The long-term effects of benzodiazepines may differ from the adverse effects seen after acute administration of benzodiazepines. [22]
Nitrazepam is a long-acting benzodiazepine with an elimination half-life of 15–38 hours (mean elimination half-life 26 hours). [12] Residual "hangover" effects after nighttime administration of nitrazepam such as sleepiness, impaired psychomotor and cognitive functions may persist into the next day, which may impair the ability of users to ...
