Ex-Abuser curious to find out if drug abuse is considered a strong risk for developing diseases such as Multiple Sclerosis? Thank you :)

Interesting question. At this time, answer is a definitive NO, as we do not find either legal or illegal drugs associated with MS risk factors. Some drugs, such as amphetamines, and cocaine, and METH, cause risk of stroke and/or heart attacks, and other drugs can cause Parkinson's like symptoms. But not MS.
