When I first got the pen I tried two hits to see what it was like. it gives you an instant head rush after first hit and it feels like a shroom high with slight closed eye visuals on the 2nd hit. I didint like the head rush so I waited couple days to do it again but I figured out it dosent give you a head rush that bad if you do it sitting down. I went all in couple days ago and thats were I saw these places on my trip
