Read a lot of different articles online and there doesn't appear to be any clarity on this. I've always avoided other substances on a day I have vaped herb to ensure nothing interacts badly with it. However, I have a coffee every morning and would love to be able to vape after but I'm wondering what the consensus is on this? Some say herb constricts blood vessels and because caffeine does the same, its not a good idea to do both within x amount of hours of each other, others say it doesn't matter? What's been your experience? Lastly, a big no no i was told was don't drink alcohol and vape herb. Do only one in the same day. Again what's your experience?
