What is your height and weight, physical activity level, smoking history (how much, how often , how many times a day, quality, etc.)? Is this pre employment or for an accident? Do you have any head shops or such in your city? Do you have a possible clean donor to substitute with? It's Percocet and Lortab btw and they don't ask for a list of prescriptions like they did in the past. Positives are handled by a MRO and they will verify scripts for prescription meds.
