Question abt narcotics contract

So my pain management doctor finally put me on something stronger (low dose buprenorphine). She did not say anything about me having a contract now but I work in a clinic myself and know how it goes. Couple weeks later I get a call saying I will need to come in for a UA in 3 months. Again, not surprising.

However, was wondering ... I smoke quite a lot of weed, which is legal in my state. I'm a little afraid to call them and ask bc what if they immediately say I've already violated my contract ? I haven't signed anything but don't know if that matters.

Do you think it would be a problem to call them and ask ? If you live in a weed legal state in the US, are you allowed to have weed while on your pain contract ?

I have enough time to quit and it might be out of my system before the UA, but it helps me sleep and nothing else really does, so I rly don't want to.
