Answer:
The most common way people get vicodin is with a prescription from their doctor. If you have a regular doctor and have intense pain, your doctor will likely prescribe it for you.
An illicit way that "drug seekers" get this narcotic is by going to the emergency room and complaining of pain. Sometimes this works and sometimes it doesn't. If the doctor that sees you suspects you of drug seeking he or she may refuse to prescribe it.
Another illicit way I have heard about, but not verified, is that you can get vicodin online. As I said, I cannot verify this.
Dentists prescribe vicodin quite often for dental pain.
Vicodin comes under the generic name hydrocodone, or sometimes referred to as lortab by doctors. It costs about 50 cents a tablet from any pharmacy.
