Not anymore man. The only way you could ever truly verify you are actually smoking purple haze and not just some other purple strain, is to be at a cannabis cup of some kind were a breeder has had a haze parent from the original strain. From what I hear, most of the seeds sold online as purple haze aren't even the real thing. But I would give the strain a shot anyway, most purple strains are pretty potent. If it looks like purple shaw, dont buy it. if you aren;t growning the strain, what maters most is quality, not namebrand. Thers plenty of strains out there better than purple haze nowadays and most don't come with the inflated name price.
