Why do you get headaches when you smoke weed on vyvanse (lisdexamfetamine)?

Not worth it, is it?: Vyv can aggravate n/a's in some people, at some doses. Mj, along with possible contaminants in the mj, certainly can have unpredictable effects, esp w/ heavy doses.Both are mind-altering substances, so it's not too surprising(is it?) that brain function could be impacted.In any event, if you are getting headaches, i suggest you not persist. Also, it's a conflict of sorts to stimulate w/ v ;"fuzz" w/ mj.
