The best high I ever had? Hm... lets seee...
Weed wise = Blue cheese. Best weed hands down I ever smoked, dankest, freshest, potent weed that has ever entered my lungs
Bubba blue w/ Hash rolled in the blunt will have a niggggie tripping.
Pills - Oxy's 80mg 1/4 - that was so fucked up.
Vics - 4 Vicodin 7.5's will have your body feeling numb (along with smoking on them is better, but since i've started taking pills I haven't been able to smoke).
Xanax - That shit is pretty great, 3 1mg footballs will make you feel like a retard, but your body feel like Jello, and make your world turn upside down.
