A pre-rolled joint, or preroll, is what the name suggests – a joint that’s already been prepared for you. Nicely wrapped and available in a variety of sizes and strains, preroll joints are ideal for anyone looking to enjoy a quick smoke on the go without any of the leg work to set up.
Pre-rolled cones are a bit different and offer a solution for consumers who want the ease of a preroll without losing the ability to choose their favorite strain. The work is done by sealing the rolling paper into a cone shape, allowing you to fill the joint with your choice of flower, then simply twist the top before smoking. 
Prerolls have several nicknames, earning their monikers depending on the size, width, wrap texture, filling, and more.
Three of the most commonly known “prerolls” are joints, blunts, and spliffs. But let’s keep things simple and focus on traditional cannabis-only prerolls.
Preroll joints have plenty of positives to them, including:
Convenience: Rather than roll one yourself, preroll joints come ready-made for you to enjoy the moment you're ready to light up.
Instant: Not only can you light up and enjoy immediately, but smoking also allows you to begin feeling the effects within moments of your first puff.
Minimal materials needed: You just need a lighter or some sort of flame to ‘spark’ it.
More compact to bring around: Prerolls come in a variety of sizes: minis, dogwalkers, pinners, half grams, full grams, or almost any size you prefer. They are also easy to store and transport, often coming in their own portable tin so your prerolls are as mobile as you are.
Easy to share: Community has always been a core principle of the cannabis community. Prerolls are an easy-to-share consumption method whether you pass around a single or buy a package so everyone gets their own.
As easy as prerolls are to enjoy, they aren’t right for everyone. Here are a few potential drawbacks to consider:
Cost: The cost of labor and materials can make pre-rolls more expensive than loose buds sold in similar weights. You may also find that your favorite prerolls only come in packs of three, six or more. But now more and more dispensary use cone filling machine to make pre roll joint. such as Tebaoyi 100pcs pre roll cone filling machine, it can fill 100pcs joint in 2 minute,also it have dutch crown device will help you close the pre rolled cone soon.

No control over quality: Prerolls have developed a reputation for being made with lesser quality cannabis, often referred to as ‘trim’ or ‘shake’. While this has changed in recent years and high-quality prerolls are now widely available, consumers shouldn’t assume every preroll on the dispensary shelf is made with high-quality flower.
Less choice of strain and quality: The selection of strains you can find in prerolls can sometimes be limited.
