It's because pot isn't regulated like other industries are. If you want to sell kobe beef, you better get it authenticated and inspected. Unfortunately, since weed is not federally regulated, there's no one forcing the growers to call a strain what it actually is.

All that happens when a club buys weed, is they take it under a microscope, check the trichromes, make sure there is no diseases or mold on the bud, maybe take a sample toke to see effects, and they offer the buyer a price. If the strain name is never given, or it's an old one that doesn't appeal to the market, the club will change it.

Think of it this way. Say a grower brings in a batch of Northern Lights, that is absolutely tear your face off phenomenol. Well, the club can sell it at $55/eighth under the name Northern Lights, and people will bitch because they're selling a "generic" strain at such a high price. So instead, they slap the name Bling on it, charge $60/eighth, and are lauded for making the premium strains cheap in the market. Now, could you honestly tell me you could tell the difference between Northern Lights and Bling, just looking at two buds? Taste a difference? I know I couldn't, and I pride myself on smoking tons of different strains throughout the week.

So what you're smoking might not be Granddaddy Purple at all, but maybe some Skunk/Haze cross. As long as it tastes lip smacking good, and gives you a gentle yet firm punch in the face, then it doesn't really matter. A rose by any other name...
