could the weed hav been laced w/somthin?
i am from a weed freindly state and have smoked weed since 1976, pretty much daily (was a grower)unless serving time, & i can tell you weed only lasts a couple hours at best,
now if it was laced with somthing (the only thing ive seen it lace with was PCP, or coke on top)
it could last while longer, (not coke though).
if this is first time , it can be like cigarettes the first time & make u nausious,
but if this persists & gets worse i would get it checked out by doctor.
If you're having trouble breathing,go to the ER. That's an emergency.
I don't know how long it will last. Try to relax,have someone with you,start dring water and cranberry juice,and if you begin to feel worse consider Urgent Care. I think you'll be fine...just don't be alone.
Keep posting here if that helps...
Forgot to mention a little trouble breathing
