How long after surgery before you can...Smoke marijuana?

Why so many people still believe that weed is something very dangerous.

When I had an operation, I decided to smoke a month after the procedure and after rehabilitation. Of course, the process was carried out without incisions. They pulled a stone out of my urinary tract without a scalpel. I guess I was lucky. I don't consider cannabis harmful to the body if you smoke it once a month. That's why I decided that after the operation, it's worth waiting one month before smoking. Many sources report that marijuana has an anti-inflammatory and soothing effect. And I believe in it.
