Do certain illegal drugs cause early Rheumatoid Arthritis, or any type of bone deterioration more than others?

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!
What type of knee brace is good for someone who has arthritis in the knee?

My right knee has arthritis. The pain comes and goes. I love jogging and tennis but it just kills me. I hate to give those up but will if it gets too bad.
But is there any good knee braces on the market that might alleviate the pain and prevent more damage?
What type of mattress would be best for rheumatiod arthritis?

My fiance has rheumatiod arthritis in his feet and ankles and in the back. He tosses and turns almost every night to where it keeps him up and also me. We are going to look for a mattress this week. Should we look more deeply into firm or soft mattress’?
