Now is the time to help someone you love who has an addiction problem. You cannot let him just kill himself with drugs and alcohol, but if you allow him to continue on the path he is on, you know he will not survive. It is hard to convince someone they need help, so instead get help from others you know are his friend. You have to combine all his friends together to fight a force as strong as addiction. The best thing you can do is to not give up. Too many people give up on their drug addict friends and leave them to destroy their own lives, instead of destroying the lives of the people around them.
Once you have a group of friends to work together you have to consider professional intervention. This is best done through drug rehab clinics that have the experience and knowledge to get drug addicts on the right track. If you choose the right place you will find caring nurses who are there to help addicts, not just there to get a paycheck. That is a drastic turn around from the days of yesteryear and that is because the focus is more focused on the patient. There was a time that people were dropped off at these places because they were simply a menace to society.
Today the focus is on the individual in need of treatment and not the people that have been affected by their behavior. It used to be that in order for everyone to lead normal lives the deviants had to be removed from society. If they were drug addicts then they would be placed in a mental institution or similar. Now drug addicts get the help they need from people that know what it is like to be addicted. Society seems to have opened its eyes to the problems and helplessness that come with addiction.
Play your part with your friend or loved one and make sure you attempt to get them going in the right direction. If they have no one to guide them to the right path, they will surely have overdoses that could very well lead to the end of their lives. If you neglect your friend, he will neglect himself. Once your friend actually knows other people care about him, you may see a transformation in him, and that could lead to full recovery.
