Yep, a buddy of mine used to call it 'greening out' only happened one time when i was still a lightweight, we had this shit called purple indigo and juicyfruit. we smoked like3-4 bowls sitting on a log in a forest, when we were done i needed help standing up i was so high. i didnt puke till like an hour later though but i was fuckin gettin the spins too so hardcore, only puked once but it was messed. that purple indigo was some good shit, thats pretty well the highest ive felt also.
