Hi, I'm brand new to vaping and know absolutely nothing. My son in law set me up with a vape, the smok Priv M17. I'm doing this for medical reasons and I had some CBD oil I figured I would try well it was tincture oil which I later read shouldn't be used because of the coconut oil and the lung problems it can cause. well, now I need to know about cleaning it out. I cleaned the tank but my concern is the cotton how do I clean it out of there or have I ruined it.
