Easy Drug Rehabilitation

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!

lol before you say anything, this is not for me. I’m writing a novel, and one of the character’s recent memories are completely wiped clean. After she disappeared for several days, she was found in a car surround by illegal drug paraphanalia, which authorities chalked up to her having memory loss. Any suggestions??
Not to be a pain, but if you could please justify/support your answer or have resources cited so i can make sure that info is solid
thanks for everything =)
