Hello and welcome to Healthcare Magic. Thanks for your query.
I appreciate your concern for your relative. It is very difficult to treat someone with an addiction problem, if they don't have any motivation to change. Any treatment given without the person's knowledge or co-operation will not be effective.
However, this does not mean that there is no hope. The best way is for his family members to convince him to see professional help. There are many psychological techniques to improve motivation - called motivational enhancement therapy - which will help convince the person to take treatment. So, please get him to see a psychiatrist
for planning further treatment.
Wish you all the best.
Dr. Jonas Sundarakumar
