Families
Families sometimes wonder about a loved one whom they think drinks too much or is using drugs.  Doesn't he/she care for us anymore? Why does he drink so much? Why do you say those hurtful things after you have been drinking/using drugs? 
These are some of the questions family members of problem drinkers, problem drug users ask.
When family members ask these questions about a loved one, it may be an indication that there is a developing problem.
