have there been any studies on the effects of crystal meth on sperm? are any toxins passed on? my son is 6 and has always been very healthy. his father was heavily into meth when he was conceived. i can't find information about a father's meth use.

*i never used meth and this man and i are no longer speaking. my son has been adopted by my husband. i just wanted to say after reading the forum - i didn't know about the addiction, he hid it from me, called it stress and depression. i was young, he was a lot older; hindsight is 20/20.*

any info is appreciated.
