Clinically we have observed that some patients diagnosed with spinal cord injury pain, particularly neuropathic pain, report less pain intensity when they quit smoking. It was therefore postulated that nicotine might affect the levels of pain intensity. The purpose of this project is to determine in a randomized, crossover placebo controlled fashion whether nicotine affects pain intensity for various subtypes of spinal cord injury pain.
