This is probably pop psychology but it always struck me that if you legalize marijuana you go a long way to solving the problem. My thoughts are... 1. It is reportedly a better pain killer in some cases than opioids so it keeps people off of the prescription opioids 2. It is nowhere near as addictive (possibly not addictive at all) 3.

Well, Colorado tried that. Recreational weed has been fully legal in Colorado since January 1, 2014. You can walk down any major street in Denver or Boulder and pass multiple outlets selling marijuana. And they've sold lots of it, according to the tax receipts raised.
The result has not been the sudden reversal of opioid addiction that you had hoped for.
In 2015, opioid overdoses in Colorado continued to increase at the same rate as prior to legalization of marijuana. That year, opioid overdoses killed more Coloradans than homicide. [0]
In 2016, the total number of opioid deaths dropped 6%, but the number of heroin overdoses continued to increase. [1]
Personal experience in Portland Oregon suggests that in that city, legal marijuana has not made a dent in the meth and heroin issues that are still affecting the city.
Maybe recreational marijuana laws have helped. Nothing in this data can disprove that maybe more people would have died without it. But it hasn't been a magic bullet. It hasn't yet gone "a long way to" solving the problem of heroin overuse.
[FWIW, I'm in favor of recreational marijuana legalization, but the problems of heroin have different roots and we can't expect legal marijuana to immediately solve those issues.]
