What are the dangers in abusing drugs?
Lots of bad things, physical and emotional, happen to you when you abuse drugs. Different drugs cause different problems, and there are many, many different kinds of drugs. You need to specify what drug you are talking about; otherwise, this question is far too general to be answered. In fact, I was going to trash it into the “Not Enough Information to Answer” Catch-All question, but I have seen similar questions asked, so I thought it might be good to clear this up.
