There are hundreds of threads on the internet discussing whether or not "Purple Haze" was or is a real strain or if it still exists today.
The consensus seems to be that there was a strain of sativa called Purple Haze in the late seventies to mid eighties. Some say the CIA wiped it out and few people deny that the original strain no longer exists. If it had someone likely would have commercialized that, but on the seedbanks there are many varieties of Haze and Purple doesn't seem to be one of them.
Then you awlays have the person on a message board who claims to have obtained some real purple haze for some outrageous price, or knows somebody who smoked it before for real, or even grows it themselves. Right.
It is some what hard to believe these people really got Purple Haze or any Haze strain for that matter because Haze has a long flowering time and relatively low yield. It seems to me this would make commercial growing impractical.
You can also try to make your buds purple by lowering the temperature in the grow room.
