Quick answer: A THC drink is a beverage holding a measured dose of cannabis extract, blended into water with a food-grade emulsifier so the oil does not float on top. In Maine, one licensed serving holds 10 mg of THC or less. Most THC drinks in our St John Street cooler are seltzers between 2 mg and 10 mg.
Key takeaways:
-
A THC drink is cannabis extract emulsified into a beverage and dosed in milligrams.
-
Maine treats drinks as edibles: 10 mg per serving, 200 mg per package.
-
The types are seltzers, sodas, teas, coffees, shots, elixirs and drink mixes.
-
Start at 2.5 mg to 5 mg, then wait two hours before a second one.
What is a THC drink?
A THC drink is a beverage, or a powder you stir into one, that carries a measured dose of cannabis extract, printed in milligrams. Because the extract is oily, a maker must break it into droplets fine enough to stay mixed in water.
That last part is the whole engineering problem. The rest is a soft drink.
The printed dose is what separates a drink from a brownie. You read a number off the can, and in Maine it cannot top 10 mg per serving.
What is actually in a THC drink?
Five things, usually: water, cannabis extract, an emulsifier, flavoring, and something for taste. Add carbonation for a seltzer or soda.
-
Cannabis extract. Distillate or a full-spectrum oil. The part with the THC in it.
-
Emulsifier. A food-grade ingredient that keeps the oil droplets suspended. Gum arabic, sunflower lecithin, quillaja extract and modified food starch all turn up in the drinks industry.
-
Sweetener. Cane sugar, stevia, monk fruit, or nothing at all.
-
Flavor and acid. Natural flavors plus citric or malic acid, same as any seltzer.
-
Extras. Terpenes added back for aroma, or CBD, CBN or CBG blended alongside the THC.
Terpenes are the aroma compounds that give a strain its smell. CBN and CBG are minor cannabinoids, present in small amounts. Research on what each one does is early and mixed.
How is a THC drink made?
By force. Cannabis oil and water will not mix on their own, so a maker adds an emulsifier and then shears the oil into very small droplets.
Picture oil sitting on vinegar in a salad dressing. Shake it and it holds a minute, then splits again. An emulsifier stops the splitting. One end of each molecule grips water, the other grips oil, so it wraps every droplet and keeps it apart.
A machine does the breaking. A high-pressure homogenizer forces the mix through a tiny gap. An ultrasonic processor uses sound waves to tear the oil apart.
Droplet size is the number makers care about. A standard emulsion lands in the micron range and looks cloudy. A nano-emulsion gets droplets near 20 to 100 nanometers, small enough that the liquid can look clear.
Small droplets also last longer on a shelf. Nanogen Labs, an emulsion supplier, told Marijuana Business Daily its droplet size holds about three years. Shelf life is the least disputed benefit of going nano.
Does nano-emulsion really work faster?
Probably somewhat, though the evidence is thinner than the marketing. Smaller droplets give your digestive enzymes more surface to work on, a sound reason to expect quicker absorption. The human data is sparse.
The clearest recent test is a 2025 crossover study in the Journal of Cannabis Research, led by Vered Hermush. Fourteen adults took 8 mg of THC and 8 mg of CBD as a self-emulsifying powder, then the same dose as oil drops.
The powder hit a higher peak THC level. Peak timing for THC came earlier too, 2.89 hours against 4.25, but not significantly. The clear difference involved 11-OH-THC, the metabolite your liver makes: 0.86 hours against 4.54.
So there is a signal. There are also only 14 people, all taking the two formulations in the same order. The authors say larger studies are needed. Read "fast acting" as a hint, not a promise.
Our piece on how long THC drinks take to kick in covers what moves timing, and how long edibles take to kick in sets the baseline drinks are beating.
What types of THC drinks are there?
Seven categories cover nearly everything on a licensed Maine shelf. They differ in volume, dose, and how fast you tend to drink them.
| Type | Typical dose | Typical format | Who it suits |
|---|---|---|---|
| Seltzer | 2 to 10 mg | 12 oz can, low sugar | Beginners, beer swappers |
| Soda | 5 to 10 mg | 12 oz can or bottle | Sweet tooth, slow sipping |
| Iced tea or lemonade | 5 to 10 mg | 12 to 16 oz can | Daytime, outdoors |
| Coffee or cold brew | 5 to 10 mg | 8 to 11 oz can | Mornings, caffeine drinkers |
| Shot | 10 mg, or up to 200 mg | 2 to 4 oz bottle | Small volume, easy to overdo |
| Elixir or tonic | Up to 200 mg | Bottle with measuring cap | Your own pour size, sharing |
| Drink mix | 2.5 to 10 mg | Sachet or stick pack | A drink you already like |
Shots are where people overshoot: 2 oz goes down in a second. Elixirs carry the opposite risk: the cap is the only thing between you and a 40 mg pour. Choosing in person is its own job, and our guide to THC drinks in Portland, Maine walks through it.
How does Maine regulate THC drinks?
As edibles. Maine statute 28-B section 102-A(29) covers any cannabis product meant to be consumed orally, naming "any type of food, drink or pill" containing cannabis. A can is treated like a gummy.
| The rule | What it means for the can in your hand |
|---|---|
| 10 mg THC per serving (28-B §703) | No licensed Maine drink sells a 25 mg serving |
| 200 mg THC per package | Bottles top out here, up from 100 mg in October 2023 |
| Measuring device over 10 mg | Big bottles ship with a cap or dropper |
| Onset warning on every label | "Effects of this product may not be felt for up to 4 hours" |
| 21 and over, photo ID (28-B §504) | No residency rule, so visitors buy the same way |
The Maine Office of Cannabis Policy writes these rules under 18-691 CMR chapters 10 and 30. Our guide to reading a Maine cannabis label explains every field.
A hemp-derived seltzer from a grocery store is not a licensed cannabis drink, and the testing differs. We compare them in hemp THC drinks versus dispensary THC drinks.
What should a first-timer know?
Start at 2.5 mg to 5 mg, then wait. That is half a 5 mg can, or a whole one if edibles have gone fine before.
The wait rule matters more than the dose. Maine labels warn effects may take up to 4 hours. Give it two hours before you decide the drink did nothing. Most rough first nights we hear about involve a second drink, not a first.
-
Eat something first. Fat in your stomach changes how much gets absorbed.
-
Pour it into a glass. You cannot pace a can held to your mouth.
-
Skip the alcohol. The two stack more than people expect, and our comparison of THC drinks and alcohol covers why.
-
Write the number down. Next time's dose is built on this one.
-
Keep the can. The label is the only record of what you drank.
If you go past comfortable, it passes. Water, a quiet room, somebody with you. Our guide for when you are too high covers the rest, and the Maine edible dosage chart lines drinks up against gummies.

Two questions get you to the right can: how many milligrams, and how long you want to sip. The Portland store page has directions and parking.
Frequently asked questions
What is a THC drink made of?
Water, cannabis extract, a food-grade emulsifier, flavoring, and usually a sweetener or an acid. The emulsifier does the real work, because cannabis oil will not stay mixed in water on its own. Some makers add terpenes back for aroma, or blend in CBD, CBN or CBG. A seltzer adds carbonation.
How many mg of THC should a beginner drink?
Start at 2.5 mg to 5 mg, which is half of a 5 mg can. Finish it slowly, then wait two hours before you consider a second. Maine labels warn that effects may not be felt for up to 4 hours, so feeling nothing at 45 minutes tells you little.
Are THC drinks stronger than edibles?
No, not at the same milligram count. A 10 mg drink and a 10 mg gummy carry the same dose. Drinks feel different because the dose arrives sooner, and because a cold can is easy to finish fast. Maine caps both at 10 mg per serving, so the numbers compare directly.
What does nano-emulsion mean on a THC drink label?
It means the cannabis oil was broken into droplets of roughly 20 to 100 nanometers, small enough to stay suspended in water and often clear to the eye. A 2025 crossover study in the Journal of Cannabis Research supports faster absorption. Its sample was 14 adults, so read the claim as likely, not settled.
Why do some THC drinks look cloudy and others look clear?
Droplet size. A standard emulsion leaves droplets in the micron range, which scatter light and give the drink a milky look. A nano-emulsion gets them near 20 to 100 nanometers, too small to scatter much, so the liquid stays clear. Cloudy is not weaker. It tells you which process the maker used.
Before your first one
The useful thing about a THC drink is that somebody already decided the dose. Read the number, pick a small one, and give it longer than you think.
