We frequently get asked about CBD doses so we’ve comprised a handy guide to answer all these questions. We’ve included everything you need to know about which dose to start with, how long you can expect before feeling the effects of CBD, how long CBD will be effective for, whether it’s working, and if it’s possible to overdose.
How much CBD should I take?
The basic answer is, it varies for each person and depends on a number of factors including age, weight, lifestyle, and genetics.
An effective dose for one person could be a few mg of CBD whilst another person may find a higher dose works better for them.
With CBD less is always more!
We recommend that you always start off with a small dose of CBD, particularly if it’s your first time taking any CBD products. Take a few small doses throughout the day and maintain the same dose for a few days. Observe the effects it has on your mind and body and then gradually adjust if needed.
How long will it take for CBD to start working?
You won’t feel the effects of the CBD immediately after taking a CBD edible. Instead, the CBD will take approximately 30 to 90 minutes to start working.
It’s important not to take more CBD in the meantime as it won’t speed-up or enhance the absorption process. Always start sparingly and build up your dose gradually because you can’t undo the amount of CBD in your system once you’ve already taken an edible.
CBD edibles might take longer to absorb but this results in a sustained effect that lasts longer than other types of CBD products. This is because the CBD is slowly released over a longer period of time as your body digests the food.
Can you overdose?
You can’t overdose on CBD. CBD is considered safe, isn’t toxic and doesn’t have any documented fatal overdose levels. A 2011 scientific study indicated that CBD doses of 1,500 mg per day were well tolerated in humans. Whilst the Department of Health and Human Services states, "no signs of toxicity or serious side effects have been observed following chronic administration of cannabidiol to healthy volunteers (Cunha et al., Pharmacology 21:127-185, 1980), even in large acute doses of 700 mg/day (Consroe et al., Pharmacol, Biochem, Behav. 40:701-708, 1991)."
In fact, according to the National Cancer Institue "Because cannabinoid receptors, unlike opioid receptors, are not located in the brainstem areas controlling respiration, lethal overdoses from Cannabis and cannabinoids do not occur."
CBD isn’t addictive either so your body won’t become dependent on taking it. This is why some people often prefer to take CBD over other potentially addictive supplements.
Can you build a tolerance to CBD?
You build a tolerance when the standard dose you’re taking no longer works so you have to increase the dose to get the same desired effects. THC is known for building up a tolerance but this isn’t the case with CBD.
With CBD you sometimes get reverse tolerance where the dose required will become smaller with time. CBD doesn’t cause tolerance because it binds to the cannabinoid receptors in our bodies in a different way to THC. Over time, THC will reduce cannabinoid receptors whereas CBD will promote increased cannabinoid receptor activity.
How long will the effects of a CBD edible last?
CBD edibles work by passing through the digestive system to be absorbed into your bloodstream. Science dictates that food can take between 6 to 8 hours to be broken down and its nutrients absorbed.
It’s possible that the CBD effects will last this long, after the initial 30 to 90 minutes for the food to hit the stomach.
There are certain factors that can influence how long the CBD effects will last for though.
If you recently ate a big meal, your stomach will need to breakdown that food before starting to absorb the CBD. This will impact on when the CBD starts to work and how long it lasts for.
The speed of your metabolism will also determine how quickly your body absorbs the nutrients from the edible. A faster metabolism will result in the CBD being processed quicker and the effects will be felt sooner.
I don’t feel a high. Is it working?
When you take a CBD edible, you won’t feel a high or a buzz that lets you know when it’s kicked in. This is because CBD edibles contain no THC. THC is the component in Cannabis that has psychoactive properties and is responsible for the "high" people experience.
Instead, people often feel a sense of calm and relaxation, whilst noticing certain things that they don’t feel such as anxiety, depression, and insomnia, amongst other things.
Why do I feel different effects to my friends?
Everyone’s mind and body is different and everyone will process CBD differently. There are numerous factors that will determine how long and how well you’ll feel the effects. These range from genetics, to physical health, age, and lifestyle.
Dosage also matters. The dose that works for one person might not work for another. Rather than comparing doses and experiences to friends it’s best to just listen to your body and find out what works best for you.
CBD quality is also an important factor as CBD quality can vary across brands and products. It’s also important to ensure you’re taking full-spectrum CBD rather than CBD isolate to get the full benefits.
