How can i find out if i have any experience with taking the drug xanax (alprazolam)?

Strange question: It sounds like you're wondering whether someone ever gave you Alprazolam without you knowing it or perhaps whether it was prescribed in the past and you don't remember. You can ask for past records from any treatment facility you may have been in or from any treatment provider that you had. You can also ask pharmacies that you used whether they have any record of you having been on xanax (alprazolam). Otherwise you can ask your doctor to do a hair analysis for xanax (alprazolam) but that will only answer the question as to whether you've been on xanax (alprazolam) in the last 90 days. Best wishes.
