St Patrick's Day THC drinks
Quick answer
For a green, alcohol-free St Patrick's Day, pour a Little Rick Mojito, our green can, over crushed ice with plenty of fresh mint and lime: 40 calories and 5mg THC per can. St Patrick's Day is March 17 every year (a Wednesday in 2027). If you're going to a parade or a long afternoon out, have one can, wait about two hours, and plan your ride home before you start.
- The green drink: Mojito, the lime-and-mint can, with a pile of fresh mint.
- The dose: 5mg cans for a day of celebrating; one at a time.
- The rule: no alcohol on top, no driving after.

Three green THC mocktails
The Little Rick Mojito
Muddle 8 mint leaves with ½ oz lime juice in a tall glass, fill with crushed ice and pour over one can of Mojito 5mg. Garnish with mint. 5mg THC per glass.
Cucumber Mojito Cooler
Muddle 3 slices of cucumber with ¼ oz lime juice, add ice and a can of Mojito 5mg, and finish with a cucumber ribbon. Cucumber and mint make it the greenest-looking drink at the party.
Shamrock Spritz
Fill a wine glass with ice, add 1 oz fresh green apple juice, top with a can of Mojito 5mg and garnish with a thin apple slice and a mint leaf. Crisp and tart, with green garnishes.

Pacing a long St Patrick's Day
St Patrick's Day often means an early start and a long day. THC drinks don't suit "keeping up" the way rounds of beer do: they take 30 minutes to 2 hours to kick in and peak around 1.5 to 3 hours. A simple plan:
| When | What |
|---|---|
| Late morning or the parade | Water, coffee, food |
| Afternoon | One 5mg Mojito |
| Two hours later | A second can or a half can, if you want it |
| Evening | Alcohol-free drinks and a ride home |
See how long THC drinks take to kick in for the details, and our strength guide if you're choosing between 5mg and 10mg.
Swapping the green beer
A 12oz regular beer is about 150 calories, according to the CDC, and a St Patrick's Day can mean several. A Mojito can is 40 calories, and there's no alcohol hangover the next morning, which helps when March 17 lands midweek. For the full comparison, read THC drinks vs alcohol.

- Keep THC cans labeled and separate from regular sodas.
- Have plenty of alcohol-free, THC-free options too.
- Nobody drives after a THC drink.
