Among is being laced another things could be any medication you were on or started between those times? I was on zoloft for 2 years and smoked with no problem but a few weeks ago I started some bipolar meds and it gave me a really freaky high that I hated and was almost to trippy for me and made me nauseated a bit. Just somethin to think about also think about your diet if you had maybe to much caffeine? Just some thoughts man.
