Hi all, this is my first post on this forum. I'm a 25 y/o male, been smoking since I was 17. So it's needless to say I am not a rookie, if I got duped I would realize it (happened lots of times on my early years). But I got this bag o' weed 3 days before, it smelled real nice, and looked real good too, sticky dank buds. But as soon as I gathered a bunch of friends and we rolled it, we all got a headache and we didn't get high, it brought us down if anything. I smoked some on my own yesterday, same thing, headaches and brought me down. I also woke up at night with a migrane and my head is really heavy today, like a bad hangover. The guy that sold me the bag is a trusted cousin, so he would never lace it with anything weird. Does anyone have any idea why this is happening? Hasn't happened to me before, my cousin proposed I let it dry so it's no longer sticky, but I find no reason as to why this is going to help the bud.
