  24. Who is addicted? Two people have been using morphine. Chris has been taking between 50 milligrams (mg) and 500 mg each day for a year. Pat has been taking 100 mg each day for six months. Only one of these individuals is addicted to morphine.

  25. Chris’s Story Twelve months ago, Chris was in an accident and received third degree burns over 30% of his body. While in the hospital undergoing treatment, the pain was very intense. The doctors prescribed morphine that Chris could self-administer to control the pain. After all, morphine is one of the most effective pain-relief medicines available. At first, 50 mg of morphine each day would ease the pain. Later, however, Chris needed as much as 500 mg a day to ease the pain.

  26. Pat’s Story A year ago, Pat lost her job. When her savings ran out, she couldn’t afford the rent for her apartment and couldn’t afford to keep her car, so she started living on the streets. Pat became really depressed. When another homeless person offered some morphine, Pat thought the drug might help make the problems of life go away. For the past six months, Pat and friends have been shooting up morphine once each day.
