It depends what kind of blood work ure talking about, they need to specifically test for drugs for the results to show drug taking, and you might just be ill, I've had shitloads of times when an illness is coming on and I'm hot as fuck and I feel almost delirious, have actually had pretty intense closed eye visuals and body sensations, and feel faint as fuck, deal with it for a week, and if you still not feeling good you're going to have to go to the doctors and talk it through with them, and they'll probly throw some pills in ure direction or a counsellor, maybe both, dunno how old u r and I'm not sure on the doctor patient confidentiality when you are below a certain age.
