I've got a friend that gets blazed after a single hit. It's pretty funny and saves me some serious money. He can barely make it through a single bowl. So weed lasts a long time between the two of us. I was pondering this a while back and realized that all he smoked through High School was swag and all I smoke is white widow or white rhino. I guess his body just never got use to the leap it quality between swag and the good stuff.
