Understanding Dosage: What Does “Grams Per Day” Actually Mean?

Overview

If you’ve received a medical cannabis document, you’ve likely seen a prescription measured in grams per day. For many patients, this is one of the most confusing parts of medical cannabis.

MR. NICE GUY makes it simple—so you understand exactly what you’re allowed to purchase, possess, and use.

What Is “Grams Per Day”?

“Grams per day” is the amount of dried cannabis your healthcare provider authorizes you to use daily.

This measurement is required under the and is used to:

  • Determine your monthly purchase limit

  • Define your legal possession amount

  • Guide your overall consumption

How Does It Translate to Monthly Limits?

Your grams per day is multiplied over a 30-day period to determine how much cannabis you can legally purchase each month.

Simple Formula:

Grams per day × 30 = Monthly limit

Examples:

  • 1g/day → 30g/month

  • 2g/day → 60g/month

  • 3g/day → 90g/month

This is your maximum allowable purchase, not a requirement to use it all.

Does This Only Apply to Dried Flower?

No. Even though it’s called “grams,” this system applies to all cannabis formats, including:

  • Oils

  • Capsules

  • Vapes

Each product is converted into a dried cannabis equivalent, as regulated by .

Example:
A cannabis oil may state that 1 bottle = 5g of dried cannabis equivalent.

MR. NICE GUY clearly displays these equivalencies so patients always know how their purchases affect their limit.

How Much Can You Carry?

Your grams per day also determines how much cannabis you can legally carry in public.

Medical patients can carry:

  • Up to 150 grams OR a 30-day supply, whichever is less

This gives medical patients significantly more flexibility than recreational users.

Does “Grams Per Day” Mean You Must Use That Amount?

No. This is where many patients get it wrong.

Your prescription is:

  • A maximum allowance, not a required dose

  • Designed to give flexibility based on your needs

Some days you may use less. Some days you may not use any at all.

What If Your Dosage Isn’t Enough (or Is Too Much)?

Your needs can change over time.

You can:

  • Increase your grams per day if you’re not getting the desired effect

  • Reduce it if you find you’re using less

MR. NICE GUY allows patients to easily update their prescription through a new consultation.
