For the last few hours I've been experiencing shortness of breath, dizzyness, tingling in my extremities,and feel like I can't take a deep breath or finish a yawn, I assume I should go to the ER but I'm concerned that they will do a drug test and I have used cocaine today, I don't think its an overdose I have been sick/allergies not sure wich but I don't want the drugs to be discovered, will they test for that
