No more Marijuana

Sage

Went to my doctors appointment today and my OB said no more marijuana which I assume the tested in my pee. They tell me to take bullshit like Tums which doesn’t work for me at all and other over the counter stuff but it’s all bullshit for me. THC is what’s been helping me so I’m so conflicted right now. His reasoning was because they don’t know what Marijuana can do to the brain development. Advice ?
