i have the same encounter lately. i got really anxious and angry. I did Bubba Dawg and Ghost OG. Both hybrids though. I couldn't trust anyone..i felt mad for no reason. weird. so i cut it down to one bowl a day instead of 2 or 3. I've been smoking for about 3 months straight. Now i just smoke sative (Green Crack) before working out. I read about the same reasons on Medical Marijuana Bootcamp site.
