A pre-roll is another word for joint. In this case, one that is already “pre-rolled” when purchased.
They tend to be rolled in a cone style with a folded paper mouthpiece.
They are convenient. Easy to use. And come in many styles and colors. This is a good way to try out different strains without making a huge investment.
They come in different sizes: 1/3 gram, 1/2 gram, 3/4 gram and 1 gram.
Some are rolled in resin or hash. Some have flavor capsules in the mouthpiece.
There is a wide variety of options of strains, growers or manufacturers.
And if you are the DIY type, you can buy empty cones and fill your own pre-roll. Empty pre-rolls are sold in all sizes: from mini-dogwalker (1/3 gram), dog walkers (1/2 gram) or a full gram.
You can also purchase paraphernalia to roll your own cone. It’s kind of fun once you get the hang of it.
It’s a far cry from the pin joint or the spliff of days gone by, and frankly…. it’s a cool evolution.
