I have a low tolerance, and yet I can keep up with my heavy stoner friends if necessary. Depending on the weed, it takes a LOT of weed to get me acting stoned; I'm one of those people who has the odd personality in my group anyway, so it's not much different, but more amplified.

My friend built a rather impressive hookah last week, and I lifted some oxygen masks from the hospital I work at, and we hooked those up to the hookah... DAMN. That was a good show!
