with some of the new vapes on the market and the ones coming out it's OK to use shake so long as there is mostly undamaged trichomes and not a bunch of floor sweepings.. things are changing, smoking is on the way out but some habits die hard so milled bud will only be of consequence for those who 'need' to smoke calyxes.. in the future I think we will see a lot of producers freeze their buds and run them through a closed loop extractor, cut out the drying and trimming and just offer live resins for folks to toot in their e-pipes or blend in their edibles..
