4mg is the most useful dose in hemp THC drinks and the hardest one to actually buy. Brands cluster at 2mg, 2.5mg, and 5mg, so the middle of the low-dose range is nearly empty. Among every brand we track, one can hits 4mg exactly: Just Chill. Below is why the tier matters, what 4mg feels like, and the closest alternatives on either side if you want options.
How we picked
- Exact dose. Does the label say 4mg THC per can, not 2mg, 2.5mg, 3mg or 5mg?
- CBD ratio. Check the CBD. A 1:1 ratio tends to feel calm. More CBD than THC feels calmer still.
- Price per can. Divide the pack price by the can count. Cans near 4mg run about $3.17 to $6.00.
- Format. Tonic, seltzer, lemonade or juice seltzer. Pick the one you'd drink anyway.
- Flavor range. Count the flavors. A thin lineup matters if you buy by the case.
Why 4mg Is the Sweet Spot
A 2mg microdose is often too light to register for anyone with tolerance, and two cans is a lot of liquid. A 5mg can is a real effect, and for some people it is slightly more than they wanted on a weeknight. 4mg sits in between: enough that one can is the whole serving, light enough that you are not planning your evening around it.
The other half of the story is CBD. The 4mg cans on the market pair THC with an equal 4mg of CBD, a 1:1 ratio that tends to make the effect read as calm rather than heady. That is a different experience from a 5mg seltzer with 10mg of CBD, or a 2.5mg can with none.
4mg THC Drinks and the Closest Alternatives
| Drink | THC / CBD | Format | Price per can | Notes |
|---|---|---|---|---|
| Just Chill ★ | 4mg / 4mg | 12 oz craft tonic | $4.38 to $5.00 | The only exact 4mg can |
| Dad Grass | 3mg / 6mg | 12 oz juice seltzer | About $5.00 | Closest below, CBD-heavy |
| Wynk 3mg Seltzer or Lemonade | 3mg / 3mg | 12 oz seltzer or lemonade | $4.00 | Closest below, 1:1 ratio |
| Cycling Frog THC Seltzer | 5mg / 10mg | Seltzer | About $3.17 to $3.33 | Closest above, best value |
| Wynk 5mg Seltzer | 5mg / 5mg | 12 oz seltzer | $5.42 to $6.00 | Closest above, 1:1 ratio |
Just Chill: The Only True 4mg Can
4mg THC and 4mg CBD in a 12 oz can, in Lemon Ginger and Rainier Cherry, at about $5 a can in 4-packs. The thing that separates it from the rest of the low-dose shelf is not the dose, it is the format: this is a flavored craft tonic rather than sparkling water with cannabinoids added, so it tastes like a drink you chose rather than a delivery method. Around 40 calories, caffeine-free. Read our full Just Chill review for taste notes and limitations. Both flavors are on Just Chill's 4mg THC drinks page.
Its narrow lineup is the honest downside. Two flavors is the whole catalog, so if you want variety across a case, a seltzer brand with five flavors will serve you better.
What 4mg of THC Feels Like
For someone new to THC drinks, 4mg reads as a clear but manageable shift: looser shoulders, easier conversation, a small lift in mood, starting 15 to 30 minutes in and peaking around 45 to 60 minutes. It is the dose most people describe as "one drink," in the sense that a glass of wine is one drink. It fades inside two to three hours.
For a regular cannabis user, 4mg is light. One can takes the edge off; two is closer to a real effect. That is worth knowing before you buy a case and conclude the brand is weak.
How 4mg Compares to 2mg and 5mg
Against 2mg: roughly double, and the difference is the point at which most people stop asking whether they feel anything. If you have been drinking two microdose cans to get comfortable, one 4mg can gets you there with less liquid and less money. See our 2mg THC drinks guide.
Against 5mg: the gap is small. One milligram is inside the range of how much a given can affects you on a given night, depending on food and tolerance. Format matters more than the number here: a 5mg seltzer with 10mg of CBD often feels calmer than a 5mg can with none. See our 5mg THC drinks guide.
The full range, from microdose to 5mg, is laid out in our low-dose THC drinks guide.
Considerations Before You Buy
The tier is thin. One exact 4mg option means limited flavor choice. If that is a dealbreaker, buy a 3mg or 5mg can from a brand with a deeper lineup.
4mg is not a starter dose for everyone. If you have never had a THC drink, a 2mg can lets you find your footing first.
Drug tests still apply. Hemp-derived THC is the same compound a test detects. 4mg can produce a positive result.
Legality varies by state, and brand shipping lists change without notice. Confirm before ordering. 21+ only, and none of this is medical advice.
Frequently Asked Questions
Is 4mg of THC a lot?
For most adults, no. It sits above a 2mg microdose and just under the 5mg most brands sell, well below a 10mg drink. Newer drinkers usually feel mild relaxation within 15 to 30 minutes.
What THC drink has exactly 4mg?
Just Chill, at 4mg THC and 4mg CBD per 12 oz can. Most brands stop at 2mg or 3mg, or jump to 5mg.
Is 4mg THC better than 5mg?
The difference is small enough that format and flavor matter more. 4mg is a useful step down if 5mg leaves you slightly more affected than you wanted.
How long does a 4mg THC drink take to work?
Usually 15 to 30 minutes, because most hemp THC drinks use nano-emulsion rather than relying on digestion. Expect a peak around 45 to 60 minutes.
Before you order, see where hemp drinks ship.
Who these are not for
- You're under 21. Every brand here is 21+.
- You live in a state that blocks them. As of September 2026, hemp THC drinks can't ship to 24 states, and 9 more only allow sellers licensed there. Check your state, then the brand's shipping page.
Skip Just Chill, the flavor-first 4mg pick if...
- You want more than two flavors. Wynk's 3mg line comes as a seltzer or a lemonade, at $4.00 a can.
- You want the lowest price per can. Cycling Frog THC Seltzer is 5mg THC and 10mg CBD at about $3.17 to $3.33 a can.
- You want more CBD than THC. Dad Grass is 3mg THC and 6mg CBD at about $5.00 a can.
- You're a regular cannabis user. 4mg will feel light. Wynk 5mg Seltzer (5mg THC, 5mg CBD, $5.42 to $6.00) is the next step up at a 1:1 ratio.
Who should pick what
| If you are... | Best fit |
|---|---|
| Want exactly 4mg in a flavor-forward tonic | Just Chill (4mg / 4mg, $4.38 to $5.00) |
| Want a little less THC with equal CBD | Wynk 3mg Seltzer or Lemonade (3mg / 3mg, $4.00) |

The bottom line
Just Chill is the only exact 4mg can we track, and it's the pick if you want a flavor-first tonic at that dose. Its limit is two flavors. If you want more CBD, a lower price or a slightly different dose, Dad Grass, Wynk and Cycling Frog sit just below or above 4mg. Decide the dose first, then the format.
