THC vs CBD, what is the difference?

Updated July 2026 · 5 min read · GreenBox Canada

THC and CBD are the two best-known compounds in cannabis, and Canadian labels list both in milligrams. They come from the same plant but do very different things. Here is the difference in plain language, and how to use the two numbers to pick the right product.

Key takeaways
  • THC is the intoxicating one: euphoria, altered perception, the "high."
  • CBD is non-intoxicating: no high, often described as calming.
  • Together, CBD tends to smooth and soften THC's intensity.
  • Labels show both numbers, and ratios (like 1:1) tell you the balance.

THC, the intoxicating cannabinoid

Tetrahydrocannabinol is the compound responsible for the classic cannabis high: euphoria, relaxation, altered time perception, appetite, and at higher doses, impaired coordination and short-term memory. It is also the number that matters for dosing, which is why Canadian packaging caps and labels it precisely. All the dosing detail lives in the edibles dosing guide.

CBD, the non-intoxicating one

Cannabidiol does not produce a high at any normal dose. People commonly describe CBD products as calming or settling, and it is widely used by those who want the ritual without intoxication. Research into its effects is ongoing, so be wary of grand health claims; labels avoid medical promises for good reason.

How they work together

CBD appears to moderate some of THC's effects. In practice, many users find a product with both, say a 1:1 ratio, feels smoother and less edgy than THC alone at the same strength. That makes balanced products a popular choice for newer users who want gentler effects.

Reading the label

2 mg THC, 20 mg CBDCBD-forward, very mildMinimal intoxication
0 mg THC, 25 mg CBDNo high at allCBD-only users

Which should you choose?

If you want the classic experience, THC is the number to watch, start low per the dosing guide. If you want to stay clear-headed, go CBD-only. If you are new and curious, a balanced 1:1 edible at a low THC dose is the gentlest introduction. Whatever you choose, the timing rules still apply, see how long edibles take, and the full picture is in the complete edibles guide.

Quick answers

No. CBD is non-intoxicating at any normal dose. Products labelled CBD-only will not produce a high.

Equal milligrams of THC and CBD, for example 5 mg of each. Many people find the CBD softens the THC, making 1:1 products a gentle option.

Yes. CBD is widely available across Canada in gummies, oils and more, with the same age guidance as other cannabis products.
