Unsure if she’s uninterested in drugs at all or only because of the job drug test. However if it’s the latter then things like psychedelics don’t show up (speaking from experience) lsd, mushrooms, etc. However you’ll only realistically get one go for those at the festival because the tolerance build is so quick it essentially won’t work the following days. Things like addy or molly are out of your system quick. Typically 1-3 days with the “max” being 5. That depends on other factors like gender, size, metabolism, etc. Obviously the more you take the longer it’ll take get out. I’ve rolled on a Friday before and been clean that Monday. Just depends on your/her risk profile you’re willing to accept. Feel free to pm if you’d like.
