The addict is not the only one affected by symptoms of addiction. There are clear signs that the pain that is caused by addiction is clearly experienced by the people around them, the people who care about them.
This undesirable situation springs by the abuser's unconscious manifestations of harmful behaviour to himself and his friends alike.
The situation goes downhill when the friendship starts to become turbulent and eventually degrades. This arrangement is about the diverse individuals who are influenced in the life of an addict.
Conformity to the group is expected from its members hence the pressure to participate in any of the circle's activities. Nonetheless, they can also find themselves addicted, due to pressure, on drug and substance abuse and this makes it harder for both of them to recover. This is the most infectious characteristics of compulsion.
Being shun by your sober friends, you tend to hang around with your new clique having the same habits as yourself. This should be able to fix your sense of belongingness only that you find yourself belonging to people who seem to head to oblivion.
New friends may be a part of the drug culture that made you addicted in the first place, which would be devastating for recovery, as it makes it much more hard to create new, more meaningful relationships that could actually help you.
