Some context to the story here; my friend just told me that they are now vaping in the morning and at night for their anxiety as their therapist prescribed. And what I thought was that they were vaping CBD or THC which I know is used to treat anxiety. But when they told me it was nicotine I was shocked. First off, the state that I live in made it illegal to sell nicotine products to people under the age of 21. I'm not a medical professional but I am knowledgeable enough to know that nicotine is one of the most addictive substances in the world. So what am I missing here? What is this doctor doing and is this a common thing to prescribe? And if this is not normal, is it illegal and could this doctor get in trouble? I don't know what to do and I do not want to see my friend get addicted due to an irresponsible doctor.
