Doesn't confirm anything, it's just a reiteration of Sam's bullshit and if you knew that guy then you would know what a nasty piece of work he is.
Sam landed at Schiphol in 1985 with his DEA handler Michael Rich and a bagful of seeds, almost certainly he got busted along with all the other guys involved in Sacred Seeds (which Sam now claims was just him alone) and made a deal to avoid going to jail for a lengthy period, that makes him a rat and rats are the lowest forms of life, anyone who's sat in a jail cell after being ratted on will agree with me on that.
Haze existed in the 60s, all this tale of the Haze Bros and Santa Cruz is just bullshit to make Sam look like the guru of ganja. Sam claims they started with Mexican and Colombian seeds and added Thai and South Indian, well, it probably is true they started growing in 71 (only 5-6 years after Sam left high school) but to claim they then bred Haze from scratch is pure, unadulterated bullshit.
Sam mixed in just enough truth to make his story somewhat credible, but it's undeniable Haze existed before 1971 and whatever bullshit Sam likes to spread.
Let's apply a little logic, in early 65 the US Marines landed in 'Nam, so within a few months US servicemen were returning home injured or on RnR, we know for a fact they brought Thai dope back with them and it was mind-blowing. This was also the time people were getting back to the earth and starting to grow their own dope.
You can't grow a pure Thai in Cali, and if you did, it wouldn't give you much weight, remember that pure Thais never produced proper buds, hence the Thai Stick - they stripped the smokeable stuff off and bundled it together, otherwise you would just have a ton of sticks with a few calyxes, that is how pure Thais grow.
Grow a pure Thai in Cali and by January it still wouldn't be done and you wouldn't have much that was smokeable even if it did finish. However, they did have strains from south of the border that did finish, Mexicans mostly, a few Colombians too, grow a pure Mexican from Oaxaca or Michoacan in Cali and you get productive plants with nice big colitas, plenty of weight for your efforts. These growers weren't stupid, they would have crossed the Thai to their established strains. That is where Haze came from, beyond that, we will never know more details.
But to claim it happened in 1971 is pure bullshit. I expect some guys in Santa Cruz did start their work in 1971 but for them to then go on to claim they invented Haze is bullshit.
Bigherb says he loves incense, seems he prefers to indulge in nonsense.
Hey, bigherb, next time you communicate with Sam, ask him about Michael Rich, the Sacred Seeds bust and his DEA ties, you know, the things that really matter when it comes to that guy.
