Doesn't forcing someone into drug rehab just creat an opportunity for them to make new drug connections?

My friend was threatened with the option of going into drug rehab or jail.

Like jail, isn't drug rehab just exposing you to more unsavory characters?

The only reason he was sent to rehab was because he was drug-tested and they found weed in his system. I know some doctors/lawyers who smoke pot often.
