Best Strains for St. Patrick's Day: 17 Lucky Picks for March 17

Quick Answer: The best strains for St. Patrick's Day are uplifting sativas and social hybrids that keep the energy going across a full day of celebrating. Top picks include Green Crack, Green Goblin, Jack Herer, and Alaskan Thunderfuck for daytime fuel; Blue Dream, Zoap, AK-47, and Sundae Driver for the bar crawl; and Granddaddy Purple for the victory lap at the end of the night.

Look, St. Patrick's Day doesn't really need a reason to be great - but having the right strain in your pocket makes everything better. The parade hits different. The music sounds better. Your friends are suddenly hilarious. The entire day is a vibe, and these 17 St. Patrick's Day weed strains are here to help you ride it from sunrise to last call.

Whether you're deep in a bar crawl, hosting a backyard hang, or keeping it low-key on the couch with good snacks and a playlist that absolutely slaps, Mellow Fellow has pharmacist-formulated options for every phase of the holiday. Here's exactly what to smoke, when to smoke it, and why it works.

Key Takeaways

• Uplifting sativas like Green Crack, Green Goblin, and Alaskan Thunderfuck are the ideal fuel for morning celebrations and bar crawls.
• Balanced hybrids - Zoap, Blue Dream, Sundae Driver - keep social energy high without sending anyone to the couch early.
• Terpenes like limonene and terpinolene are consistently linked to mood elevation and social effects, making them ideal for festive cannabis strains on March 17.
• Granddaddy Purple and Blueberry OG are the designated nightcap strains - save them for after the chaos, not before.

What Makes a Strain Worth Bringing to St. Patrick's Day?

Not every strain belongs at a holiday party. Some will send you to sleep by 3pm. Others will have you reorganizing your closet when you're supposed to be socializing. The best festive cannabis strains for March 17 hit a specific sweet spot: euphoric enough to feel the occasion, balanced enough to last a full day, and social enough to keep conversations flowing instead of killing them.

Here's what actually matters when picking your St. Patrick's Day lineup:

• Mood-lifting onset that brings the energy up without pushing it into anxiety
• Manageable potency for multiple sessions across a long day
• Social, talkative effects that match the spirit of a holiday built for good company
• Flavor complexity that makes each session feel like part of the celebration

Research suggests that terpenes play a meaningful role in shaping how cannabinoids affect mood - meaning the strain choice matters as much as the THC content. 

Limonene, in particular, has been studied for its mood-elevating and anxiolytic properties, making it one of the best terpenes for a celebratory headspace. And if you want to understand why layered cannabinoid blends tend to outperform single-compound products for social occasions, the entourage effect is the key concept to know.

The 17 strains below are organized by time of day so you can build a proper St. Patrick's Day lineup from morning warm-up to nightcap.

The 17 Best St. Patrick's Day Weed Strains

Without further ado, let’s get to the 17 best St. Patrick’s Day weed strains to take your celebration to the next level. 

Daytime Sativas: The Morning Warm-Up

Get your day started the right way on St. Patrick’s Day with these great weed strains. 

1. Green Crack - The Most On-Theme Strain on the Whole List

Green Crack on St. Patrick's Day is almost too perfect. It's green in name, electric in energy, and built entirely for the kind of alert, happy, ready-for-anything mood you want on March 17. This pure sativa delivers a sharp citrusy buzz - mango-forward with a bright, clean mental lift that's focused enough to handle pre-party logistics and energetic enough to carry you through the first few hours without a crash.

According to a study on limonene's effects on dopamine and GABAergic function, the dominant terpene in strains like Green Crack is consistently associated with mood elevation and stress relief. In short: there's a real reason this one makes you feel good.

Mellow Fellow's Euphoria Blend Green Crack 2ml Disposable Vape is one of the brand's most popular options, blending THCp, HHC, Delta 8, H4CBD, CBD, and CBG around Green Crack's signature terpene profile. It consistently ranks at the top of our best-selling disposable vapes - and March 17 is exactly the kind of day it was made for.

2. Green Goblin - The Holiday's Designated Mischief Maker

A strain literally called Green Goblin showing up on the St. Patrick's Day list? Couldn't have planned it better. Green Goblin is a sativa-dominant hybrid - widely believed to be either a renamed version of Green Crack or a specific Northern Lights x Skunk #1 phenotype - that delivers up to 24% THC alongside a citrusy, earthy, pine-forward profile. 

Users consistently report feeling happy, dreamy, focused, and creative, with the kind of social, giggly energy that's absolutely perfect for a holiday that runs on good humor and better company.

The terpene mix of myrcene, limonene, and pinene creates what researchers describe as complementary mood-modulating effects - limonene for uplift, myrcene for smooth edges, pinene for mental clarity. Research on pinene's neuroprotective and cognitive-supporting properties adds some science to what Green Goblin fans already know from experience.

Mellow Fellow carries this legendary sativa in the THCh 0.5g Disposable Vape Green Goblin, which pairs the strain's citrus-pine character with THCh for a potency-forward experience suited to experienced users who want the holiday to hit properly. Browse the full THCh collection for additional formats.

3. Ghost Train Haze - Not for the Faint of Heart

Let's be clear: Ghost Train Haze is not a beginner strain. With THC levels regularly cresting 25%, this award-winning sativa from Rare Dankness Seeds is one of the most potent daytime options on this list - and one of the most rewarding for users who know how to pace themselves. Read the Ghost Train Haze strain review for the full breakdown of its piney citrus terpene profile and cerebral, high-energy buzz.

For experienced users, Ghost Train Haze is an absolute St. Patrick's Day standout - the kind of sativa that makes you feel genuinely alive and sharp while the party is just getting started. Mellow Fellow features it in the Charged Blend Ghost Train Haze 2ml Live Resin Disposable, a pharmacist-formulated blend with THCv, HHC, H4CBD, and CBG.

4. Alaskan Thunderfuck - A Legend With a Name That Writes Itself

If Green Crack is the energy drink of St. Patrick's Day strains, Alaskan Thunderfuck is the Irish breakfast: bold, legendary, and absolutely not messing around. 

Born in the Matanuska Valley of Alaska and shaped by Northern California sativa, Russian ruderalis, and Afghani genetics, ATF is celebrated for keeping the mental high clear, focused, and social without tipping into jitteriness. The Alaskan Thunderfuck strain review makes a strong case for why this strain has maintained cult status for decades.

Terpinolene's role in mood and alertness suggest it contributes to the clear-headed, focused energy the strain is known for. Bar crawl? Creative session? Parade? ATF handles all of it.

Mellow Fellow's Motivation Blend Alaskan Thunderfuck 4ml Live Resin Disposable is built for exactly this kind of full-day occasion. The 4ml format means you've got plenty to last from morning through early afternoon without needing a reload.

5. Jack Herer - Nine Cannabis Cup Wins and Still Going

Jack Herer is named after the man who literally wrote the book on cannabis legalization, and it's been winning awards ever since Sensi Seeds created it in the Netherlands in the 1990s. 

Northern Lights #5, Shiva Skunk, and Haze came together to produce a piney, citrus-forward sativa that delivers clear focus, gentle euphoria, and some of the most enjoyable daytime energy in cannabis. The Jack Herer strain review goes deep on the terpene science behind why this one keeps getting recommended.

For March 17, Jack Herer's terpinolene-dominant profile makes it excellent for daytime celebrations: you'll feel upbeat, social, and present - not foggy or wired. Mellow Fellow's Clarity Blend Jack Herer 2ml Live Resin Vape Cartridge pairs the strain's terpene character with THCv, HHC, Delta 8, CBD, and CBG for a pharmacist-formulated focus blend that's genuinely suited to keeping your head in the game.

6. Sunset Octane - Your High-Octane Holiday Starter

Sunset Octane is the strain you bring when you want something that bridges the gap between "energized morning" and "solid afternoon" without needing to switch products. Limonene leads the terpene profile, giving it that bright citrus-forward aroma and euphoric onset, while the hybrid balance keeps things smooth as the day builds. 

Read the full Sunset Octane strain review to understand why it earns a spot on every seasonal celebration list.

Mellow Fellow's Charged Blend Los Angeles Terp Sauce 5ml Disposable in Sunset Octane is a large-format option - which, for a day as long as St. Patrick's Day, is a genuinely smart call.

The Bar Crawl Strains: Social Hybrids That Actually Deliver

Let’s keep things rolling with the best St. Patrick’s Day strains for partying all day long. 

7. Blue Dream - The Crowd-Pleaser That Never Lets You Down

Blue Dream might be the most universally liked strain in cannabis, and for good reason. A Blueberry x Haze cross from Santa Cruz, California, it delivers sweet berry flavor, a gentle euphoric lift, and that rare combination of mental clarity plus physical ease that makes groups feel good and conversations flow naturally. The Blue Dream strain review covers why it's remained a best-seller across North American dispensaries for years.

Research on myrcene - a dominant terpene in Blue Dream - highlights its sedative-adjacent and relaxing properties at lower doses, which helps explain the smooth, non-anxious quality of the high. It's the kind of strain that makes everyone feel like they're having a good time, even the friend who "doesn't usually like weed."

Mellow Fellow offers it in the Creativity Blend Blue Dream 2ml Disposable Vape and across the Creativity Blends collection for additional formats.

8. AK-47 - Chill Name, Surprisingly Peaceful High

Despite the militant name, AK-47 is genuinely one of the most easygoing hybrids in the game. Multiple award-winner, balanced-to-the-bone, and famous for a smooth, sociable high that keeps you present and talkative without burning too hot. 

Read the AK-47 strain review for the full profile - including why this strain is consistently recommended for social settings over heavier options.

For a St. Patrick's Day bar crawl, AK-47's earthy-sweet terpene blend and manageable onset make it a reliable all-day companion. Mellow Fellow's Introvert Blend AK-47 2ml Live Resin Vape Cartridge is loaded with HHC, Delta 8, CBD, CBG, CBN, THCb, and THCp - a fully layered cannabinoid blend that performs well across the board for social use.

9. Zoap - The New Kid Making a Very Loud Case

Zoap is relatively new, but it's been making dispensaries sell out since day one. Bred by Deo Farms and Deep East from Pink Guava and Rainbow Sherbet, it brings tropical, floral sweetness and a clean, balanced high that leans social without getting sloppy. 

The Zoap strain review explains why limonene, caryophyllene, and myrcene together create something genuinely special for groups.

Caryophyllene - a dominant terpene in Zoap - is one of the most studied cannabinoid-adjacent compounds in the plant, with research pointing to its CB2-receptor interactions as a potential mechanism for its calming, anti-inflammatory effects. Translation: Zoap isn't just flavorful, it's structurally built for a smooth, enjoyable social experience.

Mellow Fellow's Recover Kyoto Zoap 1ml Live Resin Disposable is a compact, convenient format that fits easily in a pocket for a full day of celebrating.

10. Sundae Driver - Everyone's Favorite, Every Time

Sundae Driver is the strain that makes the whole group happy. Cannarado Genetics crossed Fruity Pebbles OG with Grape Pie and produced a 50/50 hybrid that delivers sweet, creamy, dessert-like flavor - grape, vanilla, chocolate, a hint of earth - with a genuinely enjoyable, mellow euphoria that keeps things fun without tipping into sedation. 

This is the strain for that stretch of the bar crawl where everyone's loosened up and the best conversations of the night are just starting. The Sundae Driver strain review covers the full terpene science behind why it consistently earns this kind of praise.

Mellow Fellow's Euphoria Blend Sundae Driver 2ml Live Resin Vape Cartridge actually won Best Vape at the Alternative Products Expo's 2024 Excellence Awards. For a holiday with high stakes on good vibes, that's exactly the kind of track record you want.

11. Double Dream - Creative Clarity for the Hours That Get Interesting

Double Dream is a sativa-forward hybrid that doesn't always get the attention it deserves, but it delivers consistently. 

Read the Double Dream strain review to understand its bright berry flavor, uplifting effects, and genuinely creative, clear-headed character that makes it a strong pick for the mid-afternoon phase of St. Patrick's Day - when you still want to be up and engaged but the morning energy has naturally peaked.

12. White Widow - The Amsterdam Classic That Never Gets Old

White Widow has been a bar menu staple in Amsterdam coffee shops since the 1990s, and it's never stopped earning its place. 

The White Widow strain review covers its Brazilian-South Indian genetics, 15-25% THC range, and the balanced creative uplift it's famous for - enough energy to stay social, enough body ease to keep things comfortable. It's a classic for a reason, and St. Patrick's Day is exactly the kind of occasion where you want something time-tested.

Mellow Fellow offers White Widow in both the Creativity Blend White Widow 2ml Disposable Vape and the Creativity Blend White Widow Live Resin Vape Cartridge for terpene-forward precision.

13. White Runtz - Candy Flavor, Award-Winning Energy

White Runtz came into the world in 2017 and immediately won Leafly's Strain of the Year (2020) and first place at the 2019 Emerald Cup. 

That's not a coincidence - this Gelato x Zkittlez cross delivers sweet candy and citrus flavor, a balanced hybrid high, and the kind of consistent, enjoyable experience that makes people come back to it repeatedly. The White Runtz strain review gets into the caryophyllene-limonene-linalool terpene science behind those effects.

For St. Patrick's Day, Mellow Fellow's THCp 0.5g Disposable Vape White Runtz delivers a potency-forward version of this award-winning profile. Browse the full THCp collection for more formats in this category.

14. Cali Gas - West Coast Swagger for the Evening Transition

Cali Gas is where the energy starts to shift from "let's go" to "let's actually settle in and enjoy this." This 60/40 indica-leaning hybrid is known for bold diesel-forward flavor, lemon and spice terpenes, and a strong body buzz that comes with enough head lift to stay engaged. 

The Cali Gas strain review explains why it's a top-shelf California staple. Best used in the afternoon-to-evening window when the crawl is winding down and the hangout is just beginning.

Mellow Fellow's Desire Blend Cali Gas 2ml Live Resin Disposable captures that Cali character in a full-spectrum live resin format.

The Nightcap Strains: End the Night Right

Here are a few more great strains to round off your St. Patrick’s Day and help you get a good night’s sleep. 

15. Northern Lights - The Classic Wind-Down

Northern Lights has been helping people end their nights well since the 1980s, and it's earned every bit of that reputation. A 95% indica hybrid with Afghani and Thai landrace genetics, it delivers earthy pine flavor and a genuinely sedating, full-body calm that's ideal for transitioning from a long day of celebrating into something much more restful. 

Read the Northern Lights strain review for the complete breakdown of its myrcene, pinene, and caryophyllene profile.

Research on myrcene's sedative-hypnotic properties explains why this terpene - dominant in Northern Lights - has been consistently linked to relaxation and sleep support. 

After a full St. Patrick's Day, that's exactly the vibe. Mellow Fellow carries Northern Lights in the THCp 0.5g Disposable Vape Northern Lights for experienced users wanting deeper potency and the Dream Blend 1ml Live Resin Cartridge Northern Lights for a more balanced evening experience.

16. Granddaddy Purple - The Legend That Ends the Night Properly

If you want to close out St. Patrick's Day with something truly iconic, Granddaddy Purple is it. Ken Estes created this California classic in 2003 by crossing Big Bud and Purple Urkle, and it's been the go-to nightcap strain ever since. 

Sweet grape and berry aroma, striking purple buds, and a two-phase experience - gentle cerebral euphoria followed by a slow, full-body calm - make GDP one of the most satisfying end-of-night picks in cannabis. The Granddaddy Purple strain review covers the myrcene, caryophyllene, and pinene science behind those effects in full.

Mellow Fellow's Dream Blend Granddaddy Purp 4ml Live Resin Disposable pairs the strain's signature profile with Delta 8, HHC, CBN, CBD, and THCp - a properly formulated nightcap option that earns its place after a big day. Browse the full Dream Blends collection for additional options in this family.

17. Blueberry OG - The Smooth Closer

Blueberry OG is the rare indica that gives you relaxation without making you feel like someone unplugged your brain. A DJ Short Blueberry x OG Kush cross, it delivers sweet blueberry flavor, gentle euphoria, and enough body ease to make a long day feel like it ended well. 

The Blueberry OG strain review explains why myrcene, caryophyllene, and linalool together create this uniquely smooth ride. Research on linalool's anxiety-reducing and sedative properties gives further backing to why Blueberry OG lands so gently.

Mellow Fellow's Introvert Blend Blueberry OG 4ml Live Resin Disposable is the perfect St. Patrick's Day closer - smooth, reliable, and exactly what a long day of celebrating deserves at the end.

Your St. Patrick's Day Strain Schedule at a Glance

Tips for Actually Making It Through the Whole Day

St. Patrick's Day is a marathon, not a sprint. Here's how to actually enjoy every phase of it:

• Structure Your Strains Like a Playlist - sativas and energizing hybrids early, indica-leaning options later; flipping this order is how good days turn into unplanned naps.
• Pace Yourself Between Sessions - give each product 15-20 minutes before deciding you need more; vapes and edibles hit differently and edibles especially need time.
• Hydrate Between Everything - cannabis and long celebrations both dehydrate; water is not optional.
• Time Your Edibles Carefully - if you plan to use edibles at any point, read our guide on the best time to take an edible so the timing actually works with your schedule.
• Check What’s in Your Products - Mellow Fellow publishes third-party lab results for every product, so there are no surprises.

If you've been using the same product for a while and feel like the effects have dialed back, our guide on why weed doesn't get you high anymore has some useful context. Sometimes a strain change or a short tolerance break is all it takes.
