Varies depending on if you're just trying to get high or want to get high and have a nice flavorful experience doing so. Just wanna get high, doesn't matter, smoke that shit and cough the whole way
Still fighting with insurance to get my work done and my dentist decides to go on vacation like I expect him to be a slave at his trade how dare he vacation without my approval
Nice experience, you generally would want to consume within 6 months or so from package date, or make sure it's kept out of light and with a ~60% humidity regulation pack (like Boveda) in the container. That keeps it supple and not dried out and flavorful. Kept that way you're probably in best case scenario for like a year
Stuff I'm vaping right now is 2 years old. It sucks. Some of the THC degrades into other less psychoactive cannabinoids at that age too so not even getting the full effect from it, mega lame lol.
I've heat pressed my own weed a few times with much lower cost heat presses and have had varying success with it. Some mediocre, some some of the best dabs I've had lol. But that's pressing flower, not hash even
