I won't post the link as I have never had any luck breaking links on my IPad. There are a bunch of new headlines out of Yale university in regards to teens using E-pens to vape the unmentionable green leafy substance. Seems they are going for a panic inducing two for one, linking e-cig use with said unmentionable substance. They seem to leave out the fact that herbal vapes have been around for quite some time now and the fact that teens have been quite creative in finding ways to mask the oder of the illicit plant for generations, implying that using a vape pen is some new phenomenon. I had quite a debate with a doctor I'm acquainted with this morning on Facebook. I think I won the debate.
