I truly don’t know if I should be concerned about this…

So long story short, my husband is a recovering alcoholic. He went to rehab and has been sober now for almost 1.5 years. The other day, he made a comment about “someday” wanting to go to a cannabis dispensary and get some gummies (it’s legal where I live).

It instantly kind of struck me as weird because I have always thought with addiction, anything that’s considered to be a “mind altering” substance is off limits. I know weed isn’t considered to be addictive, but I always thought since it alters your state of mind, people who have struggled with addiction should stay away from it because it can lead to relapse.

I asked if he thought that was a good idea and he said he didn’t see why it wouldn’t be. So I just mentioned what I said above - that I thought using another substance that alters your mind was counterintuitive to his recovery from alcohol addiction.

So what I’m wondering here is 1. Am I on track with my thinking that it can put someone as risk of relapsing? I obviously don’t know if that is something that would have been discussed in rehab, so I don’t know if I’m even right in thinking it wouldn’t be a good idea for him. 2. Am I justified in being concerned about him wanting to do this? His alcoholism had gotten pretty bad and I was on the verge of leaving when he finally had his realization and got help, so I’m terrified at the thought of him relapsing. But I also don’t want to feel like I’m telling him he can’t do something. Thoughts are much appreciated.

Two side notes - I am not against weed at all. So I don’t want anyone who uses it to think I have a problem with it. My issue is directly related to the situation with my husband and his history of alcohol dependency. Also, I’m very much appreciative if there’s someone who has first-hand experience, either themselves or a loved one, who knows directly whether using cannabis can be a factor in a person’s ability to stay sober. I truly don’t know and I refuse to ask Google 😂
