Now that there is a purpose to achievements in WS3 it seems due time someone made a full, updated guide to help players figure out what the requirements are for some of the finicky secret achievements.

NOTE
This guide is complete, I likely won't be updating it more, if you find large inaccuracies or vagueness add me to make me notice it. Otherwise, enjoy, happy hunting, and please do rate, favorite, or even drop an award if this guide helped you!

There are a couple of things to keep in mind when hunting for achievements in WS3:

• The Easy Street update has added a new set of sandbox settings. When an achievement completion of 80% is obtained, additional settings are unlocked that, when altered, will disable achievement progress.
  
  • The special settings are in green text (they are sometimes available before you have reached 80% due to bugs, so be mindful)
    
  • I do not know If a save file is permanently *dirty* after having these settings enabled
    
  • If you choose to start using Sandbox after you have gained enough achievements, I recommend duplicating your save file beforehand so that you still have the backup if you want to obtain more achievements. (just save it onto two save slots)
  
  
• Most Achievements progress and status update when you enter the menu (hitting ESC). Very few of the grind achievements will pop in real time. If you think you have finished one, open the menu!
  
  
• Achievement progress is save file specific, All individual achievement requirements must be completed in one save.
  
  
• There are three potentially miss-able achievements
  
  • King Arthur: This achievement is obtained for completion of the tutorial; if you have already started and do not have it yet it is either due to skipping the tutorial or completing it before it was implemented.
    
    
  • "It" Strain: Grow 100 plants in the turd. In the starter grow room there is a turd in which you will be growing your first weed, to get this achievement you will need to grow 100 plants in that turd, finish this before you upgrade the grow room.
    
    
    • If you missed either or both of these, I highly recommend making a new account and quickly obtaining both. They are rather quick to get.
    
    
  • Party Pooper: It's as simple as the description. Reach level 69 without completing a single trippy event. trippy events are challenges that appear when you are high; you activate them by walking into hallucinations (A bowling pin, a shovel, and a rocking horse are some examples). If you only want achievements for the additional settings, I recommend skipping this one as it requires you to avoid a core progression aid for the early and mid game. If you still want to get it but have already completed a trippy event, you will need to start fresh.

These achievements are basic and will likely be unlocked by anyone playing a regular game. There isn't much, if anything, that needs to be said about these beyond their descriptions.

• To Humble Beginnings!: Grow your first plant.
  Yes.
  
  
  
• King Arthur: Collect "poop"scalibur during the tutorial
  Make sure you complete the extended tutorial, you can make a new save file to do this if you missed it.
  
  
• "It" Strain: Grow 100 plants in the turd.
  Make sure you finish this before upgrading your grow room, the toilet is removed.
  
  
  
• Get To Work!: Serve 420 customers.
  Remember when handing out freebies you can tell customers to go to your shop
  Staff members serving customers also count for this achievement!
  
  
• Baller On A Budget: Spend $42,000 of your hard earned cash.
  Yes.
  
  
  
• The Grind Begins: Grow 420 plants.
  Yes.
  
  
  
• Mr. Shop Person: Serve 4200 customers
  Staff members serving customers also count for this achievement!
  
  
  
• Skunky Doobie Doo: Roll 420 joints with your own hands.
  Auto rollers can't do this. (Amazing how helpful reading is!)
  Highly recommend getting the metal rolling table before grinding this.
  
  
• Snitches get Stitches: Knock the snitch out 50 times.
  Having your guard do it also counts for this.
  
  
  
• Street Dealer:Make 420 deals on the streets.
  Street Deals are completed by handing out doobies and selling on the spot, not bringing them to the store.
  
  
• Lil' Farmer: Grow 420 plants in your grow field.
  This is unlocked after lvl 69 the grow field is purchased as an upgrade to the lab

These are your general endgame achievements, there is nothing complicated about them, just a lot of work. You probably shouldn't focus on any of these until you're well into the higher levels (around 70+ at least) I'll leave some notes on how you can make these a little less of a pain to complete.

• Heavy Toker: Use a bong to burn through a brick.
  A brick is one kilo of weed, use a bong to smoke 1000g of your weed.
  Higher lvl bongs burn more weed at once!
  
  
• Pot Head: Smoke 1k doinks
  doinks are any smokes (doobies, joints, blunts, etc.)
  this takes a LONG time due to animations but there is a way to optimise it.
  
  The amount of time you need to smoke a doobie to use it up depends on the quality of weed used to make it, so the lower quality the doobie, the quicker the smoke. so remove any supplements or components from your grow setups, and grow some OG kush, then once it is fully grown, leave it there and let it start to mold. continue to leave the weed until it reaches 0% quality, then harvest it, then use the 0% quality weed to roll 1000 doobies. You can smoke these in a couple seconds and save yourself hours on this achievement.
  
  
• Thrifty!: Spend a $100k at the pawn shop.
  make sure to visit the pawn shop everyday and buy anything you need/want (there are often counters, rare decor, and weed storage available)
  
  
• I'll Get You the Money: Sell 500k worth of stuff at the pawn shop.
  Make sure to sell your old equipment at the shop instead of online at dump yo junk and this one shouldn't be too bad.
  
  
• Trash King: Collect $42,000 dumpster diving
  Around the trash cans on the boardwalk, there will sometimes be money you can collect. The amount of money is related to your level, will likely come naturally.
  
  
• Charlie Work: Drink 420 gallons of paint.
  paint can be bought on the far left side (when facing your stores entrance) of the map, from a homeless man.
  
  When drinking paint, try to chug it as fast as possible, paint damages you when drinking it but if you drink multiple in quick succession they don't all apply damage.
  
  
• Universal Healthcare When?: Rack up $42,000 in hospital fees.
  hospital fees also seem to be related to your level
  Just doing the paint achievement will easily net you this one as well.
  
  
• Bud Scientist: Unlock all the Hybrid strains.
  Hybrids are unlocked in the lab, you can find the recipes for hybrids by maxing your respect with influencers then asking them about "dank hybrids"
  Or you can find spreadsheets of all the recipes on the community hub.

All these achievements are related to trippy events!
https://steamproxy-script.pipiskins.com/sharedfiles/filedetails/?id=2830610494 This is an awesome guide detailing all the tripping events!

• Party Pooper: Reach level 69 without completing a single trippy event.
  If you want to get this one make sure you don't start doing these till lvl 69.
  
  
  
• Do Be Tripping: complete 123 trippy events.
  everytime you complete a trippy event its cooldown time will increase, so doing one type of event for all of these is time-consuming.
  
  My recommended games (from quickest/easiest to worst) are Mad Munchies, The Maze, Bowling, Allen Event (endgame), Red Bong Green Bong, dolphin, Chubacubras , Crab Digger.
  
  
• Bad Trip!: Kill 69 food monsters
  These are in the mad munchies event.
  
  
  
• Sea, Man!: complete the dolphin trippy event.
  this event can be found when high on the waters edge

These are the unique challenge achievements

• Flute Virtuoso: Smoke weed out of a dildo.
  These operate the same as bongs, dildos drop from dead food monsters in mad munchies if you sold yours.
  
  
• Flat Earth
  Manage to fall out of the map, I did this on a much older version so how i did it no longer works.
  
  Riding a Skateboard or any other rideable object into the ocean for a time will allow you to reach the edge and fall off, huge thanks to SpecNeeds for telling me about this!
  
  
• High Prices: Make a sale on the street for exactly $420
  Watch what your selling prices are and try moving the slider to see if $420 is one of the options, and keep trying it whenever it pops up till it succeeds. This is easiest to do in the mid game before weeds get too expensive.
  
  
• And Stay Out!
  I got this one by running around on a fresh save, beating up customers on the streets. Having the achievement complete it has a progress slider reading 42/42. According to WetCrevice it does not need to be unique people.
  
  
• Balls Deep
  Kick volley balls and beach balls into the ocean, some people say kicking one in works, some say they need a lot, just keep doing it and checking the menu and it will come eventually.
  
  
• Hot Box, Going Up!
  smoke in the elevator while it is moving in hotel 69 (across from the strip club) Easiest to do by going up to the roof (level 69).
  
  
• Dumpster Capitalist: find over a $1000 in one pile.
  
  
  
  Trash piles cash rewards are based on your level, multiplied by a randomly selected integer multiplier. Single bills can have a multiplier of 1-4 while poo piles have multipliers of 4-9. This means that the minimum level to obtain this achievement is level 112 (111*9 = 999) so don't bother till then. One of the best ways to earn exp is delivering dxxber orders while high. If you are looking to maximise your levelling speed (Contains endgame content reveals! only works once you've unlocked the endgame content it refers to anyhow):
  Unlock the Allen content, with allen bongs you can smoke allen weed to reach cosmic blasted rating which awards a 2x multiplier to your exp gain. After this, constantly call the 4 dans ship, board it, and sell to every allen you can, eventually you will reach a reputation with the onboard allens at which they will activate signs above the room doors saying weed needed, in which allens will buy weed in up to the 1000's of grams, giving more exp than a dxxber order each.
  
  
• The Fast & the Dank: complete a Dxxber Delivery in under 30 seconds & above "♥♥♥♥♥ don't go under"
  
  
  The lower quality weed requests on Dxxber (sour diesel, early queen, etc) often have closer delivery points, so do those weeds. The max lvl cart has the highest speed so use it. Make sure you are high before starting deliveries. Beyond that, all I can really say is git gud lol.
  (and also good luck!)

These achievements all have the same requirement: Spend X amount of time in Y place
And yes, these are REAL LIFE times.
(You can AFK for all of these)
These are cumulative times and don't need to be completed in one session
Remember to open your menu to get these to pop!!

• Hobo Life: spend 20 mins in a tent (you can find these on the homeless street)
  
  
  
  
• Handicapped Mile: spend one hour in a wheelchair (you spawn in a wheelchair whenever you die, no other useable chairs)
  
  
  
• Sk8ter, Buoy!: Ride a skateboard for 420 minutes (7 HOURS). These have durability so you will need multiple skateboards.
  
  
  
• Life's A Beach: Sit in a beach chair for 2 hours.
  
  
  
  
• Naughty Stoner: Sit in the strip club for 30 minutes.

These Achievements require the final content of the game to unlock (it has to do with dans and Spanish kingpins, you'll know when you've unlocked it) That's your warning, I'm not putting the whole section in spoilers,

• If Looks Could Kill: Kill El Jefe, This is achieved through talking to Allen Dan, El Jefe's quests and not necessary.
  
  
  
• Flying Dutch, Man!: Complete Allen Dan's questline, this is completed on board the IWT ship, the final quest in Dan's questline gives the ticket.
  
  
  
• Big Brain Moment: Be Maxxed (or near) high (comic blasted tier), and crunked (drink crunk sodas till the face is filled with red) simultaneously.

I don't think I really need to explain.

• Mo Money, No Problems!: Save $420,000,000
  
  
  
  
• Look How We Grown!: Grow 420,000 plants.

These achievements were made with funny numbers in mind rather than realistic goals.

For earning $420M the best method for this is unfortunately dxxber, trust me, a maximized shop is not worth the effort, it will never even return your investment, take it from someone who tested with a fully maxed shop with a 5-star rating and all influencers promoting.
There IS an easier way, however, it involves save file manipulation which I would ordinarily not approve of, however, considering how these achievements were not intended to be realistic I make an exception and leave the decision up to you. (Available at the bottom of this section)

Leave the 420,000 plants for last. Get the max sized grow room, maxed grow setups, and at LEAST one lvl 10 farmer before starting the grind. Running this will likely ruin your reputation with customers and save file so I recommend duplicating your save file for this.

• Use weed storage boxes (or another item) to build a small, short (one box tall) fence around the grow room entrance, with a small area for 3-4 AI to stand. Place all your grow setups anywhere else in the room
  
• Equip the grow sets with maxxed out components, steel pots, and add hardcore grow boost to all pots.
  
• Purchase 100,000 OG kush seeds, and plenty of components, pots, and hardcore growboost (around 10,000 maybe) (you cant buy this many in one order but if you make a max order, then click on the first recent purchase button, you can click the add to cart option multiple times to order en masse.
  
• Dump all of this material into your first lvl 10 farmer, ensure they are set to do all jobs, and let them rip.
  
• If you have more farmers purchase another 100,000 seeds for them, along with pots and components if they are capable (still hire them if they are not capable).
  
• AFK but if you are near a level up or quest complete remember that this will pause the game, you may need a slow auto clicker for night time.

Farmers don't need to reach a field to operate it, they get as close as they can path and then service, if your farmer annoys you you can trap them in a corner any time as well. The farmer AI struggles working in teams, they will try to do the same jobs a lot but it's still faster with more farmers, if only slightly.

This guide is for windows, I don't know the things you need on other systems.
To Gain $420M easily:

• Purchase an item of high value (the best option being the designer leaf, but other highly expensive decor or the 420-inch TV works as well.
  
• Save you're game (note which save slot) and close the game.
  
• Go to the start menu, type %appdata% and open the folder. Navigate to the local low folder (will have to go backwards one folder first)
  
• Enter the weedgames folder, Open the weedshop3 folder and open the notepad that pertains to your save file (WS3 is auto-save, WS3_0 is the first slot, etc.)
  
• Press ctrl+F on the keyboard and type in the name of your item (the designer leaf's name is DecoDesignerLeaf, however just designer would be enough). Change the number next to quantity to a high number (a few hundred will be tons).
  
• I didn't bother to compile a list of other decors names but you can probably guess them or just scroll to find them.
  
• Save your changes, close the file, and relaunch the game, you will now have that many designer leaves, go to dump your junk and sell them off!
  
• Selling tons of the same item to the pawn shop will decrease its value rapidly so dump yo junk is more reliable on large scale... and quicker.

And that is all 42 of Weed Shop 3's achievements!

for 80% completion you only need 34 achievements. Personally, I would recommend these achievements as the ones to not bother with if you only want 80%:
Mo Money, No Problems
Look How we Grown!
Party Pooper
Dumpster Capitalist
The Fast & the Dank
Pothead
Sk8ter Bouy!
Do be Tripping
