I recently found out that my school (A state university in the US, I am not naming for confidentiality) has free programs and counseling for drug addiction. I don't' know how comprehensive it is, but it is a good start for those looking for help and those who don't want to pay for an expensive program. I looked online, and many other universities and community colleges have counseling centers that offer similar services. To those looking for free/low cost options, look into what is offered by your school! If you are already paying tuition, you might as well take advantage of the resources available to you.
