POT TV – MrTV18 reviews a Cold Creek Kush pre-roll from Seven Oaks.
A lot of pre-rolls have a bad wrap.
Once cannabis has been ground up the mono and sesquiterpenes, along with other resinous compounds, change and degrade at an accelerated rate. Rolling papers tend to suck out oils and dry even the best flowers after a few days. Unless stored with care (and, best, rolled with hash or cigar-like intent), even a great pre-roll can go stale quickly. However it should never been un-smokable.
MrTV18‘s review is, apparently, as harsh as the flower tested.
