Even in states where cannabis is fully legalized, using it in public is forbidden. You can expect to receive at least a hefty fine, if not a criminal charge, depending on where you live. Therefore, you can only use it in a private residence.

Rules surrounding CBD are a little different. Like marijuana and specifically THC, CBD is not legal federally. Do NOT assume it is ‘legal in all 50 states’ because that isn’t true. When it comes to cannabidiol, each state has different laws regarding legality, and whether you can use it in public.


Therefore, we don’t encourage the use of cannabis in public and urge caution if you use CBD.

However, if you are intent on vaping on the go, discretion is essential. You need a vape device that is easily concealed and fits in your pocket or handbag. It should also only take a couple of seconds to have a hit before you ensure it is removed from the public’s view.

This guide will help you determine the best discreet vape pen, but remember, you use cannabis in public at your own risk. If you want to avoid getting into legal trouble, it is best to stick to CBD in states where its use is permitted.

1 – KandyPens C-Box Mini

You will struggle to find a more diminutive vape pen from a top-rated brand. The C-Box Mini stands just 68mm tall. It is a magnetic 510-threaded battery that works with CBD and THC cartridges. The hole is designed to fit the majority of popular vape cartridge types. Any cartridge or tank with a diameter of less than 11mm should work with the C-Box Mini.

Any cartridge or tank with a diameter of less than 11mm should work with the C-Box Mini.

It is also just 25mm wide, so you can easily hide it in your hand. The C-Box Mini also fits snugly in the pocket and doesn’t result in any weird bulges. Despite its size, this vape pen has a surprisingly powerful 390mAh battery. It is also straightforward to use:

  • Choose the magnetic adapter you wish to use.
  • Screw the cartridge into it.
  • Put the cartridge and adaptor into the battery’s cartridge receptacle.
  • Inhale from the mouthpiece to begin, as the C-Box Mini is draw activated.

With a heat-up time of just 2-5 seconds, you can enjoy a clandestine hit as you walk down the street. Even a 2-second draw provides decent flavor. If you are hidden from open view for a little longer, you can pull on the C-Box Mini for up to eight seconds. This vape pen also includes a micro-USB port for charging.

The only downside is that you can only use the C-Box Mini for liquids and oils. However, for $25, it is an absolute steal.

C-Box Mini Pros

  • Draw activated, so no need to fiddle with buttons.
  • Heats up in a handful of seconds.
  • Extremely small but versatile enough to fit most popular vape cartridges.

C-Box Mini Cons

  • You can’t use it for dry herb.
  • Not particularly powerful in a general sense.

2 – Vaporesso Renova ZERO

At 80.2mm high, the Vaporesso Renova ZERO is another tiny but mighty vape device. It is a little thicker than the C-Box Mini at 31mm but is still small enough to hide in your hand. The ZERO was the brand’s first all-in-one device and has some excellent features. It is ideal for newbies to the world of vaping and contains a condensed version of Vaporesso’s OMNI chip. As a result, it has three power settings, automatic temperature control, and various other safety features.

As it is a kit, the ZERO comes with the device, a refillable pod, an e-juice refilling bottle, and a charging cable. The three temperature settings are:

  • Low: 9W
  • Medium: 5W
  • High: 12W

Safety features include overtime protection, short circuit protection, and pass-through protection. The ZERO is leak-proof, and putting the oil into the device is really easy.

Please note: You must use the refill bottle provided as its spout is specifically designed for the pod. The ZERO has one button which you use to switch it on and off. It is draw activated, so wait a few seconds for the liquid to heat up and start using.

There are LED lights on the ZERO to inform you of the power setting, and also the battery level. The device has a 650mAh battery, so you get better flavor and clouds than with the KandyPen C-Box Mini. At just $30, the ZERO kit is outstanding value for money.


  • Relatively strong battery.
  • Only one button to worry about.
  • Excellent build quality.
  • Leak-proof.
  • Easy to switch pods.


  • Restrictive draw.
  • You’ll need to replace the pod coils after about five refills.

3 – BBTank Vape Key Box

The vape device looks like a car key, so no one will look twice when you take it out of your pocket. It is just 62mm high with a diameter of 11mm. The 510-threaded connection replaces where the key would usually go on a key fob. As a result, you can store your cartridge within the fob during travel.

The vape device looks like a car key, so no one will look twice when you take it out of your pocket.

To use, push the front-facing button, and the cartridge will immediately spring open. Press the ‘fire’ button on the side of the BBTank five times within two seconds to turn it on. Press and hold the ‘fire’ button to start heating the liquid. The battery cuts off power automatically after 15 seconds of continuous usage.

The 350mAh Li-ion battery gives you a surprisingly large amount of use on a single charge. However, it takes a considerable length of time for it to charge fully. While the BBTank isn’t the most sophisticated vape pen around, for less than $20, it does what is expected.

BBTank Pros

  • Cool car key fob design.
  • Useful safety features.
  • LED indicator to let you know when it is charged.

BBTank Cons

  • Requires pressing the power button five times, and pressing it again to activate.
  • Takes up to four hours to fully charge.

4 – Voopoo Drag Nano

At just 54.5mm, the Drag Nano is even smaller than the C-Box Mini! The one downside in terms of private use is the fact that the word ‘Drag’ is written on the side of the box! It looks like a tiny version of the Voopoo Drag Platinum but doesn’t have buttons or a screen. Despite its size, the Nano has a 750mAh battery, which is surprisingly powerful.

You get one pod with Nano, and it has a 1ml capacity. It is extremely well-constructed and has a cute necklace that you can wear as a lanyard. The pod clicks into the battery, and it is secure enough to withstand a fall. The overall performance is extremely reasonable when you consider it is a budget vape pen.

The LED lighting tells you the charge status of the battery. It is green when there is 61%+ power, blue when there is 21-60%, and red when it is below 20%. Most users get around 2.5 refills from a single charge. You should be able to buy the Nano for under $35 online.

Voopoo Drag Nano Pros

  • LEDs are easy to see.
  • Beautiful design.
  • Reasonable flavor and smooth hits.
  • Pods are securely held in.

Voopoo Drag Nano Cons

  • The vapor is potentially too cold for some users.
  • The 1ml capacity is relatively small.
  • The refill port isn’t wide enough.

5 – SMOK Novo 2

As you can guess, the Novo 2 is an upgrade on the original Novo. Its 800mAh battery is large for a device that is just 88.3mm high. It weighs only 43 grams, so you will hardly notice it in your pocket. The Novo 2 has a 1.0-Ohm pod for e-juices and a 1.4-ohm pod for nicotine salts. Both pods hold up to 2ml of liquid. With a total of 40 colors to choose from, you are sure to find a design that you love.

With a total of 40 colors to choose from, you are sure to find a design that you love.

As it is so light, the Novo 2 isn’t as durable as one might hope. The bottom is rounded, so it doesn’t stand up on its own. However, these are minor quibbles as it is an elegant vape device. It has a U-Shaped airflow, which means there is an airflow hole on each side of the pod. This design draws air in through the sides of the device. There is no way to adjust the airflow, but it works well for mouth-to-lung vapers.

The Novo 2 has impressive battery life; it can last up to two and a half days of heavy vaping. When the LED light is green, it means the device has at least 70% battery. It turns orange/yellow in the 30-69% range, and red when it has less than 30% battery. The pods take a while to break in but provide outstanding flavor when they do. You can expect consistently good flavor after several refills.

If you have $32 to spare, you will love the Novo 2.

Novo 2 Pros

  • Extremely easy to change pods.
  • Fantastic flavor.
  • Good draw.
  • Long battery life and pod longevity.

Novo 2 Cons

  • You have to lay the device flat because it doesn’t stand up.
  • The hole for refilling is small.
  • You can’t replace the coils.

Final Thoughts on the Best Discreet Vape Pens Ever

Although it is an ever-changing list, we believe that the vape pens outlined above will remain useful devices for a couple of years, at least. Each one is tiny and fits snugly in your pocket. You can also conceal them in your hand. They are all light, portable, and relatively affordable.

While none of these vape pens produce massive vapor clouds, that is kind of the point! Once again, we have to point out that using cannabis in public is illegal, even if adult-use marijuana isn’t.
