Totally depends, so without my knowing anything about the place in question take this with a grain of salt: all of the inpatient rehabs I experienced were really overbearingly negative experiences except one, so that is 1/6. Those first five did much more to harm than help, other than perhaps getting me not to use for X amount of time. So unless you are worried about using in the very near future, I would say you would almost certainly better off with a quality outpatient program than quality inpatient program. Inpatient programs are more for people in crisis mode. Are you in crisis mode? If you are just trying to get apart from society for a while, go on a meditation retreat for a week somewhere, you will find it as a beginner even much more benefitial.
