nah its not laced with anything... I know that for sure... and I do smoke mids to... its just been recently for the past month or so... I have been smoking more though so thats probably got something to do with it.... went from smoking once everyday to smokin like 5-6 times a day... gota love summer... but for some reason I am starting to have the same wierd head ache even when I dont smoke... just not as intense...
