Just to name a few similar threads from the past, I can mention the...freediving while being high on drugs
I no longer do drugs. In the past I did them because they did a wonderful job of killing anxiety/panic. But I have since discovered, that there are other ways to get rid of stress that are just as effective (Reminding myself that the voice in my head telling me to freak out is simply my reptilian brain talking and should not be listened to, for instance. I read a great book called "Why Zebras Don't Have Ulcers")
(But before anyone gets confused by what I just said, this particular thread was never about drugs. I only asked my pot-vaping friends for info because, I don't know anyone who vapes normal plants.)
