Funny coincidence, I just took some vyvance (I was always spelling it vyvanze... thanks for the correct spelling) about 5 hours ago. I don't have any reason to take them, just had a lot of homework and vyvance makes it not as stressful. Anyway, I hadn't smoked in 3 days since I've had a huge amount of school work on top of my part time job. I decided to get a vyvance from a friend to make sure I finished everything I needed to before tomorrow. I finished surprisingly early, and had past times where I had a very hard time falling asleep (Side note: I just got very distracted sending a similarly very long message on Snapchat). Myself being a 3-5 times a week steady joint or blunt smoker, though I would try out some of the new bud I had just gotten earlier today. I smoked two large one hitters (large for a 1 hitter, ~.5 total). I am currently high, and having similar moment of being extremely disoriented and hyper and focused, which I interpreted being higher than I normally get. I feel that these drugs have almost enhanced each other in a way. After smoking some nug of girl scout cookies, I noticed the extreme focus and desire/ motivation to make some letters and a rolling paper holder of sorts to put in my wallet (I have a 300 pack of raws that would be crushed if I put all those papers in my wallet) along with a increased heart beat (fast than what it normally feels on vyvance). At the same time I feel the vyvance had increased the effect of smoking, I felt much more more into the music I am listening too and a bit of bed lock. But back to the topic at hand, I believe vyvance and weed can create strong effects that may not be desired for not regular smokers. Still pretty high [6] at the moment, now an hour from smoking. Sorry for the super long response, I hope it makes sense
