Sam was pretty self-destructive: He drank alcohol heavily and smoked marijuana and tobacco frequently. He would steal sedatives from the medicine cabinets of his friends and family for his own pleasure, too. What reproductive system problem is he more
likely to have than other men of the same age? What can Sam possibly do about that situation?

It is important to follow the directions for using these medications.
