Good questions.

I have a couple of people who have terrible anxiety when they are around a lot of people, so doing things such as going to class in college can actually be stressful for them.  They take this pill and they say it nullifies their stress for the day, so I'd have to say yes.  Of course you would need to try it out (I'd suggest buying 1-2 pills when I put them up for sale) and decide for yourself. 

As for the second question it will not show up on a drug test.  Because this is a concoction of herbs and vitamins I am 100% transparent on what is in the capsule (I won't tell what form or what dosage), so you will be able to double-check that there isn't anything on the list that would raise a flag during your specific drug test.

Hope those answer your questions, if not let me know and I'll give it another shot!
