I think that only China does that, and just for show purposes. I don't think they have any statistics available
China only executes the drug traffickers (as does most of the region: Malaysia, Indonesia, Philippines, Singapore, Taiwan & Thailand) and it hasn't helped a bit. In fact drug use is on the rise: an eight-fold increase over the last decade. Much the same as the net result of the outstandingly expensive War on Drugs: heroin is cheaper and more available than ever before.
BTW on Chinese Executions: Until 1996, execution in China was always by shooting - and often public. They now use lethal injections too and at prisons. Unless it's the SAR in which case there is no death penalty.
All in all the Vancouver trial seems like a sensible avenue of inquiry: you'll never get rid of drugs or drug users, so perhaps trying to reduce the crime associated with it by reducing the cost of the drugs is the way to go.
Arresting heroin addicts for drugs and the crimes many need to do to fund their habit is no doubt several magnitudes more expensive giving them free heroin, and all in all a big waste of police & correctional services' time and resources.
Will it increase the number of drug addicts? I think it's unlikely, if the government involved starts on a course of offering honest, believable information about both the pros and cons of drugs.
If it does we can take some solace in the following:
a) It's a personal choice of the individuals involved.
b) It'd have to increase the number of users several-fold before it starts to work out more expensive than the present system.
c) One can always go back to the present system.
