I actually don’t think it matters what specific substance is being used as the idea is the same. I can’t say about literature because I didn’t pay attention if it mentioned other substances, but I know at the meetings there were always people whose family members smoked pot or did heavy drugs. It was quite a few years back when I needed it

Plus honestly many addicts use more than one substance. I know alcoholics who regularly smoke pot, periodically do hard core drugs etc many mix it with pills etc

Addicts are addicts. You didn’t cause it and you can’t cure it

Overall the whole idea is what can you do for your well being and safety regardless of what they are doing. It’s about you, not them
