Do not snort Xanax or any Benzo for that matter unless its Versed/Midazolam. Then you can shoot that if so inclined.
Here is a good article for yall.

Link above is about intranasal use of Benzos and interesting.

While there are no reports of nonenteral routes for buspirone, there are several benzodiazepines that can be administered intramuscularly or intravenously. There are a few reports on the use of sublingual benzodiazepines and many on rectal administration of benzodiazepines. Nasal administration of short-acting benzodiazepines (midazolam) are used for preanesthetic or anesthetic medication and can even be safely used in children.47 This route for psychiatric purposes is not reported.
A review paper on the rectal administration on diazepam concludes that this is an excellent alternative for the management of seizures.48 The author reviewed eight papers, which concluded that rectally administered intravenous diazepam reaches therapeutic levels in 5 to 10 minutes. Therapeutic levels were between 754 ng/mL and 98.5 ng/mL and were based on seizure control. According to this review, the recommended administration is undiluted diazepam intravenous solution inserted with a small syringe.
Sublingual administration is reported infrequently, but three papers on alprazolam and lorazepam indicate that this is an effective route. The pharmacokinetics of sublingual lorazepam were compared with intravenous, intramuscular, and oral lorazepam in 10 subjects.49 For sublingual and oral administration, patients were asked to fast overnight and then received two standard 1-milligram tablets that were held under the tongue for 15 minutes. Blood samples were drawn at 5 minutes and then at intervals up to 48 hours for the 10 subjects. The mean peak plasma concentration was 23.3 ng/mL for the sublingual dose vs. 24.9 ng/mL for the oral dose. Peak concentration occurred at 2.35 hours for the sublingual and 2.37 hours for the oral dose. The systemic availability was 94.1% sublingual and 99.8% oral. The authors conclude that sublingual lorazepam, given on an empty stomach, could be substituted for both oral and intramuscular lorazepam.
The kinetics of oral and sublingual alprazolam were studied in 13 fasting volunteers.50 A 1-milligram tablet was used for both the oral and sublingual administration, and blood samples were drawn at 5 minutes and then throughout a 48-hour period. The mean peak plasma concentration for the sublingual dose was 17.3 nanograms per milliliter and 14.4 nanograms per milliliter for the oral dose. Time of peak concentration was 1.17 hours sublingually and 1.73 hours orally. As with lorazepam, sublingual alprazolam is basically equivalent to the oral dose.
A third mention of sublingual lorazepam or alprazolam is from a letter to the editor and describes one author's experience.51 The author concludes that lorazepam or alprazolam tablets chewed or held under the tongue give patients relief from panic symptoms in as few as 2 minutes. There is no discussion of sample size or pharmacokinetics.
