Can You Vape Too Much CBD? Effects of Excessive CBD Vaping


Too Many Puffs of CBD? What are the Effects?

OK, you’ve got your CBD vape pen already to go.

You take a few puffs and start to feel relief. Then you take a few more puffs and feel even better.

Then before you know it, you are reaching for your CBD vape every 10 minutes.

And you think “Hey, can I vape too much CBD?  Am I going to overdose?”

Well, can you vape too much CBD?

Of course.

But relax – it’s not a big deal.

You Can’t Overdose on CBD

You can definitely take too much CBD, but you can’t overdose.

Some people shouldn’t vape CBD. But for everyone else, there is no danger of an OD.

CBD Won’t Shut Down You Brain

When you drink alcohol or take opioids, they go right to your brain stem and slow it down. That’s the part of your brain that regulates your breathing and heart rate. If you take too much, you pass out – or die.

CBD – no matter how much you take, does not effect your brain stem. There is absolutely no danger of respiratory depression from CBD – or THC for that matter.

That’s why there just aren’t any deaths directly related to too much cannabis.

“No recorded cases of overdose deaths from cannabis have been found in extensive literature reviews” – 

CBD is Not Toxic

Did you know acetaminophen causes more liver failure than anything else? 

It is highly toxic to your liver. So are a lot of other things.

Not CBD, though.

They just haven’t been able to find CBD levels high enough to be toxic. 

You probably would have to take 500,000 mg all at once to hurt yourself.

Vaping CBD gives you 1 mg -2 mg per puff. It would take 250,000 puffs in 15 minutes to kill you.

It is impossible to OD on CBD by vaping.

OK, vaping excessive amounts of  CBD won’t kill you. But can you do it too much?

The Consequences of Too Much CBD Vape

The worst thing that happens when you take too much CBD is that you waste perfectly good CBD.

After your CB2 receptors are filled up, they close shop temporarily. All the excess CBD in your system gets metabolized and excreted. So you are just flushing expensive CBD hemp extract down the toilet.

Biphasic Effect

We are just starting to learn about how the body tolerates CBD. One issue is that CBD seems to have a biphasic (two phase) effect.  In other words, your body reacts a certain way to a normal dose, but reacts differently at higher doses.

Generally, at very high doses, you start to lose the benefits of CBD and the initial problems that you were trying to address may start to reappear.

So one consequence of vaping too much is that you might come full circle and your symptoms may start to come back.

This is very important to be aware of since you might conclude that CBD is not working – but it may just be the dosage.


CBD vaping is a wellness tool. It’s not like vaping nicotine products for recreation.

Vaping CBD safe. But it is not 100% risk free. There is no reason to vape CBD all day long – especially if you are at all concerned about any adverse effects of vaping.

Sleepiness or stimulation

Some people feel slightly sleepy or stimulated if they have taken more CBD then they need.

The effects are mild and can be compared to that of herbal teas or supplements.

Throat Irritation

Some CBD vape products are a bit hard on the back of the throat. Vaping too much can give you a slight cough or scratchy throat.

Neck Tingle

For myself and other people I’ve spoken to, a gentle tingle on the back of your neck let’s you know when you’ve had a sufficient amount of CBD.
