Weed vape cartridges at our California dispensaries
Facts checked Sep 2026
A cannabis vape is a cartridge or all-in-one pen filled with a lab-tested cannabis oil that a battery heats. The oil is a concentrate, so it counts against California's 8 gram daily concentrate limit, not the flower limit. The label carries the total THC and CBD in milligrams, the batch number and the packaging date.
Shop vapes on the live menu
Stock, strains and prices differ by store and change through the day; the menu is the only place on this site that says what is on a shelf right now.
The vape shelf holds two formats. A cartridge, usually half a gram or a gram of oil, that screws onto a rechargeable battery with a 510-thread connection, and an all-in-one pen with the battery built in and nothing to screw together. Both hold a concentrate: an oil made from cannabis by a licensed manufacturer, tested by a state-licensed lab and sealed with a batch number.
What differs between the products on the shelf is the oil inside. Distillate is a refined oil, often with terpenes added back. Live resin and rosin are less refined and keep more of the plant's own terpenes. The label names the type, and our label guide explains what those words mean on a box.
Cartridges, pods and all-in-ones
A 510-thread cartridge fits any 510 battery, which is nearly every battery sold on the accessories shelf. Pod systems use a brand's own shape and fit only that brand's battery; the box says so. An all-in-one pen is disposable in the sense that it is not refilled, though most models are rechargeable and are meant to be used to the end of the oil. If you do not own a battery, an all-in-one is the simplest first purchase.
What the label has to show
The box carries the universal symbol, the government warning, the net weight of oil, the batch number and the lab's figures for total THC and CBD, printed in milligrams per package. Oil potency is high compared with flower because it is a concentrate; the milligram figure is the honest comparison between two carts, not the percentage. Every cartridge is tested for the same contaminants as flower and concentrate, and the certificate of analysis is available at the counter.
Vapes and the daily limit
The oil in a cartridge is concentrate, so it counts toward California's 8 gram daily limit on concentrated cannabis, by the net weight of oil on the label. A one gram cartridge is one gram of that 8. It does not count toward the 28.5 gram flower limit at all, so a basket of flower and carts is measured against two separate figures. The purchase-limits guide works through an example.
Keeping a cartridge working
Store a cartridge upright, at room temperature, out of direct sun and never in a hot car; heat thins the oil and it leaks into the mouthpiece. Charge a battery with the cable it came with, and if a cart stops drawing, check the connection before assuming the oil is gone. Keep pens and carts in their child-resistant packaging and out of reach; they look like ordinary pens, which is the problem.
Questions people ask
- Do I need to buy a battery with a cartridge?
- For a 510-thread cartridge, yes, unless you already own one; the accessories shelf has them, and any 510 battery fits any 510 cart. A pod system needs that brand's battery. An all-in-one pen has the battery built in and needs nothing else.
- Does a vape cartridge count against the flower limit?
- No. The oil in a cartridge is a concentrate, so its net weight counts toward the 8 gram daily concentrate limit and not the 28.5 gram flower limit. A one gram cart is one gram of the 8.
- Why is the potency on a cart written in milligrams?
- Because the state labels concentrates by the amount of THC and CBD in the package, in milligrams, rather than by percentage alone. Milligrams per package is the like-for-like comparison between two cartridges of different sizes; the percentage tells you how concentrated the oil is, not how much is in the box.
