Speaking of pot smokers in strange places, my cousin lives in Colorado, where they've made pot legal, and he opened up the door one cool mountain morning to find some guy passed out on their lawn with a spliff in either hand.
Turns out the nutcase had used a stronger brand that his standard (as he explained once he came around in the ambulance) and gave himself some kind of heart palpitation or asthma attack or something like that. Apparently, this isn't the first time the smoker had done this.
So, yeah, not to say that pot's bad, but my cousin has had about five insanely stoned people wandering around his property before. He has a pool, so if he doesn't lock the back door, he ends up with a stoned party in his back yard in their skivvies.
