Include it as an option in sentencing for petty crimes, maybe, like they’re doing with the Community Courts here in Vancouver: jail or treatment. Add a proviso that statutory release (at 2/3 of sentence) or any parole requires such a vaccination if there was any evidence of drug abuse. You could also include it as a precondition for the return of children that have been apprehended due to the parent’s drug problem.

Now they need to come up with the same thing for heroin, crystal meth, etc. Good luck with alcohol, though, since it always exists at low levels in the body it’s impossible to generate an immune response to it without causing autoimmune disorders.

I would never advocate mandatory shots of anything to anybody, but if it is kept optional or part of thier good behaviour for early release it could be benificial. No one can over come an addiction unless they really want to.
