Breathalyzer BAC tests measure the presence of methyl compounds in the subject's breath, using a ratio to estimate the level of alcohol in the blood. While a number of factors may influence this test and result in a false reading, most medications will have no initial effect on a BAC breath test. Xanax, a benzodiazepine, will not show up in a breath test, though it will show up in a toxicology blood test.
Can I drive on Xanax?
Benzodiazepines like Xanax are depressants, just like alcohol. Typically prescribed for anxiety, these drugs have the same effect as alcohol as it relates to the operation of a motor vehicle.
If you are prescribed to Xanax, consult your doctor about whether it is safe to drive when you're taking the drug. Always follow the prescribed dosage, and be aware of the potential side effects. If you are just starting your prescription, take your dosage for a few days before you drive or operate machinery so you can get used to how the drug will affect you.
Drinking while on Vicodin
Drinking while on a benzodiazepine will intensify the depressive effects of both drugs on your nervous system. Make sure to talk to your doctor about your drinking habits before you start taking a drug like Xanax, as mixing certain dosages of the pill with alcohol can be extremely dangerous.
Because Xanax and alcohol work in tandem on the nervous system, you may be heavily impaired after drinking only a small amount of alcohol. Police can arrest you for DUI if a number of physical checks indicate impairment, so even if your BAC test comes in well under .08, you can still be charged with a DUI.
If you don't have a prescription
Xanax is a controlled substance. If you don't have a prescription, it is illegal to ingest the drug, and because it is a powerful depressant in certain dosages, unregulated ingestion presents the possibility for overdose, especially if alcohol is involved.
How to take a breath test
DUI lawyers disagree on how and when it is best to take a breathalyzer test and when it is in your best legal interest to refuse a test. It's best to use as much caution as possible when assessing your ability to drive under the influence of alcohol or drugs, and proper planning and a self-imposed zero-tolerance rule will ensure that you never have to take a test at all.
If you are given a breathalyzer test, be forthcoming with officers to ensure that the test is administered fairly. If you have a cut in your mouth, have vomited recently or are a diabetic for instance, your breath test may produce a false positive.
