I would say no. Ambien is a Non Benzodiazepine, which means it offers similar effects of a Benzo, but is not classified as a Benzo it will not register as a Benzo on a drug test. Valium is a Benzo so it would come up positive for Benzo's regardless of it being Valium or Xanax.
yes
Valium and Xanax are both under the class of benzodiazepines which is what they both would show up as on a urine drug screen.
Short answer: Yes They only test for key chemicals in drug tests, this way they can get a larger common denominator. Benzodiazapam is found in Valium, Xanax, Librium, Serax, and Rohypnol, however it is unlikely that any person or party would need or want to know the specific drug you are taking. If you had a prescription for Xanax and took Valium recreationally, no drug test would be the wiser. However unless you are taking large doses of Xanax on a regular basis, expect the drug to be completely out of your system in 1-2 weeks.
No. Ambien is indicated for insomnia. Xanax is indicated for anxiety.
Any narcotic with a pure opiate base will show up on a drug screen. So, yes, it will be positive for opiates. Xanax is not a narcotic. However, it will show positive for benzodiazepines (Same family as valium.)
benzodiazepine (i.e. Lithium, Valium, etc.)
Loritab is an Opiate, Xanax is a Benzodiazapine. Xanax is in the same family as Valium, but has a shorter half life, this increases the euphoria assiciated with the drug.
Xanax isn't a narcotic, so no.
Librium is a benzodiazepine and therefore, like Xanax and Valium, will show up on most drug test kits (if they test for benzodiazepines.)
yes
Valium reacts slower, doesn't hit as hard, but lasts longer 20-100 hours. xanax reacts faster, hits harder, but lasts 6-12 hours.... .5mg of xanax is comparable to 10mg of Valium xanax imo is better for anxiety, sleep Valium more so for relaxation and muscle relaxation, especially after a hard workout. Valium stays in your system longer, xanax does not.
they both fall under the category "benzodiazepines" which is a category on most drug tests, but a lab can easily figure out what drug triggered the benzodiazepine reaction. most drug test will be testing for the ingredients of the benzodiazepines, not the drug it came from. a much more advance and expensive test would be required to determine if it came from xanax, koltipin or Valium because they are all benzodiazepines. This came from a doctor.
