Generic ones ive got on the street not so much. But these ones my buddy gets with his green card from a dispensary they come from phyto labs or some shit by way of colorado, it's really well done and legit. The flavour is very good and strong. Ive had about 6-7 different strains in the past few months and im pretty sure i could identify each and every one. I think it comes down to a couples aspects, if theyre using just herbs or a mix of herbs and trim. And how sophisticated their extraction technique is (ie highest quality butane, high tech vac purge etc.)
