how much cbd oil should i vape

How Much CBD Should I Take the First Time?

The safety and long-term health effects of using e-cigarettes or other vaping products still aren’t well known. In September 2019, federal and state health authorities began investigating an outbreak of a severe lung disease associated with e-cigarettes and other vaping products . We’re closely monitoring the situation and will update our content as soon as more information is available.

Figuring out how much CBD, or cannabidiol, to take is more complex than it sounds. While cannabis has been around for forever, CBD products are relatively new. As a result, there aren’t any evidence-based dosing guidelines yet.

Most experts agree that if it’s your first time using CBD, starting with the lowest dose and gradually working your way up is the best way to go.

Here’s a look at what you should know before trying CBD for the first time.

For starters, your body weight and individual body chemistry affect how you tolerate CBD.

Here are some other factors that play into how much CBD you should use.

How you take it

There are a few different ways to use CBD. The form matters when it comes to how much you should take, how it’s absorbed by your body, and how quickly it takes effect.

The different forms include:

  • oils and tinctures
  • edibles
  • pills and capsules
  • creams and lotions
  • vaping

Doses vary among forms. For instance, a standard dose in CBD gummies is around 5 milligrams (mg) per gummy, while tinctures and oils contain about 1 mg per drop.

Capsules and edibles can also take longer to kick in than a spray or tincture.

What you’re using it for

People use CBD to treat everything from nausea to arthritis pain. What you’re using it for matters when deciding how much you should take.

For instance, the Arthritis Foundation recommends starting slow with just a few milligrams of a sublingual form of CBD twice a day and increasing the dose by the same amount after a week if you don’t get enough pain relief.

That recommendation may not be the same if you’re using CBD for another condition.

Other medications

If you’re on any other medications, it’s important to know exactly how much, if any, CBD you should take.

CBD is usually well tolerated, but there’s still limited data on drug interactions. CBD could change the way a drug is metabolized, and there’s some evidence that it may interact with blood thinners, immune suppressant drugs, and antidepressants.

If you’re taking any other medications, speak to your doctor before using CBD.

It depends on how you take it.

Edibles, such as gummies, have to go through your digestive tract before they’re absorbed. By the time this happens, the actual amount of CBD that ends up in your system could be fairly low.

Another form, such as a tincture that you take sublingually, gets absorbed directly into your bloodstream, meaning it kicks in faster.

CBD onset time

Here’s a look at how long it generally takes to feel the effects of different forms of CBD:

  • Edibles: up to 2 hours
  • Tinctures sublingual sprays: 15 to 45 minutes
  • Topicals: 45 to 60 minutes
  • Vape products: 15 to 30 minutes

Re-dosing is one of the most common reasons why people end up taking too much of anything. If you take more too soon, you could end up with unwanted effects.

Again, CBD is generally well tolerated, even at high doses, but that doesn’t mean it’s harmless.

Taking too much could result in:

A recent animal study also showed that high doses of CBD may cause liver damage.

Start low and slow, and make sure you give the CBD ample time to work before taking more. The general rule of thumb seems to be sticking with a low dose for about a week before increasing it.

In general, the effects of CBD last from 2 to 6 hours, depending on how you use it, how much you use, and your tolerance.

To better understand how your body reacts to it, take some general notes when using CBD, including:

  • the amount you took and how you took it
  • when you started feeling the effects
  • how strong the effects were
  • how long the effects lasted

This information can help you decide how much to take next time, as well as when to take it.

Ready to dip a toe into the world of CBD? These tips will help to unsure your experience is as comfortable, safe, and effective as possible:

  • Shop smart. CBD products are largely unregulated in the United States. Mislabeling and poor quality control, including significant discrepancies in strength and undeclared THC, or tetrahydrocannabinol, are an issue. Only shop from trusted, licensed dispensaries.
  • Ask a professional. A healthcare provider who knows your medical history is the best person to go to for advice about how much CBD you take. As knowledgeable as sales staff may be when it comes to CBD products, they aren’t healthcare providers. Your best bet is to consult both.
  • Use it before bedtime.Drowsiness is one of the most common side effects of CBD. Unless your healthcare provider advises otherwise, using CBD at bedtime — or when you have time to chill if you need to — is a good idea, at least until you know how your body responds to it.
  • Avoid vaping. Vaping has been linked to serious lung infections and even death, though it’s not exactly clear how or why. While the Centers for Disease Control and Prevention (CDC) are investigating the risks of vaping, most government health agencies recommend avoiding vaping until we know more.

CBD is typically safe and well tolerated, but it’s not a one-size-fits-all solution. There are several factors that play into how much and how often you should use it.

Until experts come up with clinical guidelines, your best bet is to talk to your healthcare provider, especially if you’re using CBD to manage a specific condition or regularly take a medication for a specific condition.

Is CBD Legal? Hemp-derived CBD products (with less than 0.3 percent THC) are legal on the federal level, but are still illegal under some state laws. Marijuana-derived CBD products are illegal on the federal level, but are legal under some state laws. Check your state’s laws and those of anywhere you travel. Keep in mind that nonprescription CBD products are not FDA-approved, and may be inaccurately labeled.

How Much CBD Should I Vape?

The global interest in the food supplement Cannabidiol (CBD) is at an all time high, and while sublingual oils are the most common way to take CBD, vaping it is also becoming more commonplace with more users flocking to this method to consume CBD.

So why are vapes proving a popular way to use CBD?

Cannabinoids such as CBD have different absorption rates dependent on the way they are used. Vaping CBD offers the highest bioavailability (absorption rate) of all widely available methods and the shortest onset to feel the effects.

Using CBD hemp in a vape can be done in a few ways. You can either use vape e liquids (also called e-juice) or concentrates such as shatter/wax/crumble.

There is no pre-defined dosage when it comes to vaping CBD oil. Everyone is different when it comes to how much works for them.

However, the most common way to work this out is to start low and go slow.

Meaning, you begin with a small amount and increase the dose incrementally across time until you find your sweet spot, and this way you can work out if you are subject to any of the common side effects of CBD too.

In the simplest terms, you can inhale a puff, and wait 5 mins to assess how you feel and continue until you find what how much CBD works for you.

How does vaping CBD make you feel?

If you are thinking about trying a CBD vapouriser device for the first time, you probably wonder what the difference is between using CBD vape oil and CBD drops.

Regardless of consumption method most people find CBD feels lightly stimulating in small doses and relaxing in larger doses.

There are a few specific advantages should you decide to use a CBD vaporiser over sublingual drops:

  • Effects are felt near immediately, peaking within a minute or so.
  • Stealthy. If you use a pure CBD concentrate there is no smell (assuming no terpenes) and often little vapour.
  • Useful if you already vape as it’s a matter of changing cartridge or using a CBD additive.

Now if you’ve decided starting to use a CBD vapouriser is for you, it’s useful to work out how much CBD is in your vape and per puff. This way you can easily track dosage and should be able to quickly figure out how long a bottle of juice will last you.

You need to work backwards to do this, let’s run through an example below:

Working backwards

To do this, you need to work backwards to find out how much CBD will be in a millilitre (ml). Let’s start with CBD e-liquid as this is the most popular format of CBD vapes at the moment.

Look at your CBD vape oil bottle and read the ml in the bottle; usually these are between 10ml to 30ml. Once you have the bottle size, look at the amount of CBD in the container; given in mg (milligrams).

Now we have the two essential elements to figure out how much CBD is in each ml; this is helpful as vape pens, cartridges and tanks all hold different amounts of juice. For simplicity, we are going to assume the cartridge size is 1ml.

Let’s assume our vape juice is 30ml and contains 1000mg CBD. Doing some quick maths indicates we have 33.3mg CBD per ml (1000/30 = 33.3).

Can I vape CBD oil?

On the whole, no you cannot vapourise CBD oil used under your tongue. Most CBD oils used sublingually are not suitable for vapourisers due to the diluent used. Instead, there a specific CBD products developed for vaping such as concentrates, CBD e-liquid or a CBD vape pen.

Be careful as CBD oil could clog up your vape pen or worse damage your health, but any CBD products suitable for multi-use will state this quite clearly and will contain the same type of diluent found in CBD e-liquid such as propylene glycol (PG) or vegetable glycerin (VG).


Bioequivalence refers to the dose you would need for the same amount of CBD to enter your bloodstream for a different way to consume CBD than you are currently/have previously used. This makes it easy to figure out how much CBD you should take when first trying CBD e-liquid or concentrates.

If you are brand new to CBD and have no benchmarked dose to compare against, instead you can skip to the next step and look directly at how much CBD is in each puff, and use this information to work out your bioequivalent dose when you find your ‘sweet spot’.

Comparing absorption rates of 33.3mg vaped vs 33.3mg used in tinctures can give some pre-emptive guidance, especially if you already use CBD oils and are looking to try a vape pen.

On average, vaping is thought to have 56% bioavailability, whereas oils are assumed to be around between the 15%-30% mark. Using these figures it’s easy to work out the equivalent absorption rate (the equal amount absorbed in the bloodstream given an adjustment in consumption method).

33.3mg vaped gives 18.6mg absorbed into the bloodstream assuming 56% bioavailability.

33.3mg used sublingually gives 9.99mg absorbed into the bloodstream assuming 30% bioavailability.

1 – (18.6/9.99) = 0.86. Meaning on average, 86% more CBD is absorbed when vaped vs when used sublingually. Thus, you would need 62mg CBD sublingually to have a similar absorption rate as when vaped (33.3*1.83 = 62).

If you are already using CBD oils, checking much you dose can given quick insight into calibrating your ‘sweet spot’ for vaping! You can use the same method as described earlier to work out the CBD mg per ml in an oil bottle too for comparison if needed. All Nature & Bloom products have this information listed on the product detail pages.
