My brother moved in with me six months ago, and I love him to pieces. A few months in I realized he had been smoking methamphetamines, and a few weeks ago I walked in on him smoking in his room which is adjacent to mine.

I have a very weak constitution and have been hospitalized four times in the last five months for various reasons; none of which are related to each other, and am very concerned that I have been exposed to the drugs. I am currently three months pregnant and it's hard enough dealing with the hormones let alone my brothers issues. I am afraid of confronting him about this problem as he has been known to be unstable in the past.

Any advice which can be offered I would be extremely grateful for.
