Seriously? You reference what is basically an ad, for a product which is derived from marijuana? I've read the studies on CBD, even tried it for pain relief. Other than a placebo effect, I think it's overrated. Vaping, on the other hand, helped me quit a 30 year tobacco habit. Cut down on my coughing, and has had no adverse effect on my health.
In addition, I can control the amount of nicotine in the niquid. I have come down from 25mg to 5, and I plan to continue to decrease until I stop completely.
Butt out. Your source is questionable at best.
