What is a weed pen?
A weed pen is a battery-powered vape for cannabis. You will also see it sold as a THC vape pen, a THC pen or a weed vape. A small battery heats a coil, the coil turns the oil into vapour, and you breathe it in through the mouthpiece.
Nothing burns, so there is no ash and no smouldering end. The oil inside is far more concentrated than bud: our pens and carts list 88 to 90% THC, against 27 to 36% for the flower in our pre-rolls. That is why one slow puff goes a long way.
The 4 types of weed pens
Every weed pen falls into one of four groups. The difference is what goes inside and how much setup it takes:
| Type | What goes in it | Setup | Suits |
|---|---|---|---|
| Disposable pen | THC oil, sealed in with the battery | None: inhale, and it fires | Anyone who wants zero fuss |
| 510 cart and battery | A screw-on cartridge of THC oil | Charge, screw on, click | Regular users who rotate strains |
| Wax pen | Wax, shatter or rosin you load yourself | Load, heat, clean the coil | Dabbers who want a pocket rig |
| Dry herb vape | Ground bud | Grind, pack, wait to heat | Flower smokers who want vapour |
Disposable weed pens
A disposable is the whole kit in one body: battery, coil and oil, sealed together. Ours have no buttons and no settings. You draw on the mouthpiece and the pen heats on its own.
"Disposable" means you do not refill it, not that the battery dies early. Our 2g disposables recharge through a USB-C port (bring your own cord), so the battery keeps up until the oil runs out. The Cherry OG 2g pen is one of them: sweet cherry first, then an earthy OG finish as you breathe out.
510 carts and batteries
A 510 cart is a small glass tank of oil with a coil in its base. It screws onto a separate battery, and "510" is simply the thread size, so almost any cart fits almost any battery. When the cart runs dry, you keep the battery and buy another cart, which is why people call the pair a cart pen.
Our carts, like the candy-sweet Grape Ape cart, hold 1ml of 90% THC distillate with strain terpenes. The 510 battery comes in three sizes with three heat settings. Screwing one on, picking a voltage and fixing a cart that will not hit are all in our guide on how to use a 510 cart.
Dab pens and wax pens
This is where the names get muddled. In most Canadian online shops, "dab pen" means a disposable oil pen like ours. A true wax pen is different: it has an open chamber that you pack with wax, shatter or another concentrate, and it needs cleaning between sessions.
We do not sell refillable wax pens. For concentrate flavour in pen form, the Frumpz live rosin dab pen holds 1g of solventless live rosin over a postless ceramic coil, a design that lets thick oil reach the coil with less clogging. The same rosin comes as a Frumpz live rosin cart for 510 batteries.
Rigs, nails and dabbing itself are covered in what dabs are and how to dab.
Dry herb vapes
A dry herb vape heats ground flower until it gives off vapour, without setting it alight. It is the closest thing to smoking bud, but the device is bigger, takes a minute to heat up and needs regular cleaning. We do not carry them.
Disposable vs rechargeable weed pens: how to choose
For most people it comes down to a disposable or a cart on a battery. Three questions settle it:
- How often do you vape? A few puffs a week suits a disposable, since there is nothing to set up or keep track of. Daily users tend to settle on one battery and swap carts as they empty.
- Do you like switching strains? A 1ml cart holds half the oil of a 2g pen, so carts let you rotate through more flavours before committing to one.
- Do you want control? Our battery has three voltage settings and a two-click pre-heat for thick oil. Our disposables run at one fixed heat, which is simpler but leaves nothing to adjust.
On cost, a 2g disposable works out slightly cheaper per gram than a 1g cart, and carts need a battery up front. Carts leave less behind, though: the battery stays, and only the small glass tank is used up.
How to tell a good cart from a bad one
You cannot see inside the coil, but the label, the oil and the first few pulls tell you most of what you need to know:
- The label names the maker, strain and THC. A cart with only a flavour name and no maker or THC figure tells you nothing about what is inside.
- The oil looks clean. Distillate should be clear and golden. Murky oil, floating specks or oil that has split into layers are bad signs.
- It moves slowly. Turn the cart upside down at room temperature and the air bubble should crawl, not race. Oil that sloshes like juice may have been thinned, though this is a rough check, not proof.
- The hardware is tight. There should be no oil around the mouthpiece or threads, nothing rattling, and the first pull should taste of the strain rather than hot metal or burnt sugar.
- The seller says what is in it. Our distillate carts are THC distillate refined in-house in BC, blended with strain terpenes, with no cutting agents or fillers. Any seller should answer that question plainly.
Packaging that copies a famous American brand, or a box with no maker named at all, is the usual sign of a cart to skip.
How to use a weed pen
A disposable needs no setup. Take off any cap, draw slowly for two or three seconds, and the pen fires by itself. With a cart, charge the battery, screw the cart on until it is snug, and hold the button as you pull.
Start with one or two small puffs, then give it a few minutes before deciding on more. If a disposable stops making vapour while there is still oil in the window, it needs a charge.
