I have this problem with people who use OxyContin, marijuana, and relief in the same sentence. Alarm bells go off.
The level of pain relief wasn't quite the same. She did get a greater amount of pain relief with the oxycontin, but she would also remain in bed for about 16 to 18 hours a day when taking it. It was an effort for her to get up and use the bathroom. She couldn't cook anything because she would constantly doze off.
With MJ, she was more able to function normally, even though she didn't get quite the same level of pain relief.
