Ive helped many friends and family members kick bad drug habits and one thing people usually dont realize or take in to account is that when someone is addicted to a drug its not them they are no longer who they where the choices they make the things they do the people they hurt the person drug free in all likelyhood would never do those things but when under the control of a drug the drug is making their choices for them and some people once hooked arent strong enough internally or mentally to take control and kick their habit its sad really.
