Sadly, we are not insured from people with mental problems in society. You can meet them even in medical staff where people should be professional. So it's better to find out about a clinic or a rehab before sending there a person with addiction. I know what I am talking about because I had to experience few rehabs. My son got drug addicted about three years ago. Classic situation he got in a wrong company. Okay, he shared that with me and I was shocked but first thing that came into my mind was rehab. I told my son "Look, we will go through that but without your will and intention it will be very hard to get rid of your addiction. So first local rehab we tried I didn't like at all. Too much pills, not enough attention. So I changed the rehab to another one. This rehab is totally different. After few months my son has changed a lot. He got rid out of drug addiction and got stronger mentally. I am very thankful.
