Nah, I had only a few lit. At the time I was in Portland living in a small 1947 Spartan trailer. I had one lit in the front of the room, one by my laptop besides me, and one in my kitchen. Before long the whole trailer was hazy and when I stood up I almost collapsed from all the smoke. I had to catch myself on the wall reaching for the handle to open the front door. I ended up crawling out the front door panting for air HA HA.
