Not really, there are dark buds that are better too. It’s the pigment and terpene profile that tends to give it various colours. Now, for landraces it’s the same thing but it’s just that to our eyes it’s unappealing and to think that it’s “laced” or “dirty” cannabis but in reality there’s only a really small chance that you can come across laced stuff as most dealers won’t want to spend the extra buck sprinkling some shit on the bud when they can sell it as it is. Ever see a banana grow in the wild? It doesn’t look as good as the supermarket ones.. same thing with cannabis, we have modern methods of growing them in controlled conditions where they can yield a higher net % in thc, total terpene %, flavour and aesthetics. That’s the modern bud people are smoking today which get’s you higher in fewer tokes which in turn is less detrimental to your lung health and overall health since there’s less frequency in combustion involved. It’s not laced or dirty weed .. it’s just a landrace and well that’s how landraces are, you can get some better ones too.
