oxy's are around most of the time...(my source for singles dissapeared...but i've been offered bulk amounts) $25-$30 for an oc80
percs are always around...$5 a pop or $300 for 100
benzos+other opiates...dunno really...wish i could find a source for benzos
probably the easiest way is to get a script for them
i know there's a methadone program in toronto (i don't have the phone number or address though...but you should be able to find them easily)
it's not very easy to get on the program though (at least that's what my friend who wanted to get in said....according to him (and his MD) you have to apply a couple of times for them to let you on it)
if you're into injecting your opiates (as you might end up being if you do get in the opiate scene) then make sure you check out the safe injection clinics (there's one on queen and carlaw i think)...they'll set you up with supplies and harm reduction info
