Oh right, I was never exactly sure how privatised healthcare systems worked regarding insurance etc; it sounds like you only need to pay for healthcare if your insurance rating is bad. (I was under the impression you had to pay through the nose for all healthcare, and if you had no money you wouldn't get any medical treatment).
I'm in the very fortunate position of receiving state-subsidised healthcare-I pay nothing for prescriptions and medical attention. It comes with a trade-off however; the quality of care I receive is probably lower than private healthcare, and the waiting lists are enormous-I could be waiting up to 4 weeks to see a doctor even in an emergency, and up to six months for hospital appointments, even for routine procedures. Also, I recieve minimal face time with NHS medical professionals-my last doctors appointment lasted a mere 3 minutes, and it was a pretty serious problem I had, too. I don't know if it's any different where you are, though?
So, I guess there a pros and cons to each: cost versus quality.
BTW over here, if you're not eligible for free scripts we pay £7.85 (roughly $12 US) per prescription, whether that's a one day 'script or a one month 'script, so maintaining a suboxone habit can still be quite costly even under our subsidised system.
