Discussions of "big pharma" aside, this seems like a classic case of treating symptoms and not causes.
If you consider that the cases likely to present for vaccination are the more serious ones, you're going to be preventing people from taking one drug. If they have a serious need they will just take a different drug. Inoculate them against all the common drugs and they'll start mixing household chemicals and then you have a dramatically worse situation (google for the effects of 'krokodil' if you have a strong stomach).
It would probably be better to help these addicts work through their problems so they don't need drugs. Leaving them unable to fill a need through conventional means just forces them down unconventional paths.
Why do we have such an obviously backwards approach to drug abuse? :(

Because the intelligentsia have been taken over by a religion that says people are born pure and can be punished back into virtue if they get contaminated. Growing up in quiet high-IQ enclaves, their personal history is that unpleasant consequences teach better behavior. It is outside their life experience that there could be people who are too stupid to see logic, too distracted to notice lessons, too impulsive to act on logic, or too neglected in early childhood to develop susceptibility to social influences.
