I agree with Zinco, that seems very unethical. Especially since cannabis is commonly used to treat PTSD. I don't live in a state where it's legal or medically available, but I know several people who truly benefit from the medicinal effects of cannabis. I know a 50-something war veteran who smokes heavily. He also has a PTSD dog. Anyway, that's ridiculous that you were refused treatment because you smoke cannabis, especially in this day and age. My pdoc knows and secretly encourages my use. If anything, quit smoking for a little bit so you'll get the treatment you need. Or don't, and lie. Either way, you're in the right. Good luck!
