Adderall and DMT

So my husband is prescribed adderall, he truly does need it so he does take it daily, I have done some research but am getting conflicting information, what is everyone’s thoughts on smoking dmt while taking adderall? He has been smoking for a while now and never had any issues but here recently he hasn’t been able to breakthrough…I’m not sure if the adderall had anything to do with that if this issue is a recent issue. I’m just trying to help him figure out why he can’t get in. I know dmt has a “mind of its own” and there’s multiple things that could be happening but I wanted to attempt to rule this out. Thank you!
