Has anyone successfully quit using marijuana and if so, how did that affect your OCD?

I ask this because I started smoking daily when I was 16 to cope with CPTSD/GAD, but found out at age 19 that I have OCD also. I'm deciding to quit for a variety of reasons, but ultimately to better my life. I have an upcoming appointment to discuss medication for OCD (mainly pure O), but I'm wondering if quitting smoking long-term will lessen the anxiety enough to not need medication... has anyone had experience with this kind of situation?
