Tramadol is a Schedule IV controlled opioid requiring a valid prescription from a licensed clinician, so "no Rx overnight free shipping" offers are illegal and pose life-threatening risks. DEA and FDA warn that such sites are rogue pharmacies selling counterfeit pills often laced with fentanyl, leading to overdose deaths and addiction. Consult a healthcare provider for proper evaluation and prescription if appropriate, then use only state-licensed pharmacies that verify prescriptions and follow safety standards—avoid all no-Rx free-shipping scams.
