Why does my left arm keep going numb?

I am relatively healthy, I have never had a stroke and I am fully aware of what the symptoms of a stroke are.
But basically ever since I have stopped smoking weed and synthetic weed, I often get this tingling / numb feeling in my left arm, mainly in my ring finger. I still have feeling in it and I can move I perfectly, it just feels uncomfortable. It happens mostly when I think about it, otherwise it doesnt happen at all.
