I know all illegal drugs are bad, but are certain ones known to cause Rheumatoid Arthritis, or any type of bone deterioration, over others? I have used a few in the past, and now at 22, I am suffering from an advanced case of bone damage in my hands. I have also been diagnosed with Fibromyalgia. Please help with real facts, Rather than just “Drugs are bad”. I will be picking the best answer. Thanks!
