Why do I need to know the dose?

Many people use cannabis to have a specific effect, including, but not limited to reducing chronic pain, managing anxiety, or feeling the euphoric effects. In order to understand how to reproduce desired effects while trying different products, you need to know how much Tetrahydrocannabinol (THC) and Cannabidiol (CBD) you took.

The general rule is to START LOW AND GO SLOW. Start with a small amount when you are trying a new product, strain, or potency for the first time, if it’s been a while since you used cannabis, or if you’re new to cannabis in general. After you try a small amount, you may decide that you want stronger effects for next time and from there you can easily increase the amount you take slowly over days or weeks. If you have ever over-consumed cannabis before, you can appreciate how unpleasant it is. It may be easier to have more cannabis but you cannot undo the amount you took! Given the stigma of smoking, many choose to use edibles or oils for their cannabis consumption; however, these products have the highest risk of over-consumption due to the delayed effects.

When you understand how to find the dose of CBD and THC you can use that information to get the most benefits from your cannabis use. If you are using cannabis to help alleviate a specific symptom or manage a chronic health issue, this information is essential. The state of clinical research on cannabis use and various health conditions is in the early stages of understanding. Due to the illegal status of cannabis, along with other concerns (i.e regulatory issues for research) for so many years in Canada and all over the world, cannabis studies are just now reflecting the positive outcomes of cannabis use. This means that when it comes to using cannabis for therapeutic reasons, the process is based on personal trial and error. Experimenting with different types of cannabis strains and gradually changing your dose over time is the only way to find out if a treatment is effective.

Please note that this calculator can only provide estimates based on the accuracy of your cannabis product label, therefore black/grey market or homegrown cannabis products without testing by Health Canada certified labs are difficult to calculate accurate dosages. Consumers are encouraged to be extra cautious and start low, go slow!

For edible cannabis products and cannabis oils, it can take 30 minutes to 2 hours after consumption to begin to feel the effects, but up to 4 hours to feel the full effects. Effects can last up to 12 hours, and some residual effects could last up to 24 hours after use. It’s best to wait at least 1 hour after your first dose before deciding to have more to avoid overconsumption.

For smoking and vaping, it can take seconds to minutes after consumption to begin to feel the effects, but 10 to 30 minutes to feel the full effects. Effects can last up to 6 hours, and some residual effects could last up to 24 hours after use.
