I haven’t smoked cigarettes since the Surgeon General declared smoking a hazard to health, but I must admit to inhaling every now and then since. And because a friend went into a business associated with vaping, I’ve been able to try vaping “juice,” not with nicotine, but with herbals like menthol, eucalyptus and lavender. I might be exhaling steam, but it behaves like smoke, making it perfect for me to study the patterns and understand what smoke does as it drifts through the air…and to blow smoke rings. When I was sixteen, I must have thought it was the height of sophistication to be able to blow a perfect smoke ring; now, I think it would make a good painting.
