Or you can chew used coffee grounds. Used or spent coffee grounds still contain a significant amount of caffeine. A study conducted by The Department of Nutrition, Food Science and Physiology, School of Pharmacy, University of Navarra found that spent coffee grounds contained 3.59 to 8.09 milligrams of caffeine per gram of used coffee grounds. That's 41mg of caffeine in 7 grams of used coffee grounds.

There's also chocolate-covered coffee beans, such as Jitterbeans. The most potent of these is Crackheads 2, gourmet 60% cocoa dark chocolate covered espresso bean with a crunchy candy shell with a big caffeine boost added! 600mg of caffeine per box. Each box of Crackheads2 contains the same caffeine in approximately 6 cups of coffee, 7.5 Red Bull energy drinks, or 11 cans of Mountain Dew.

The raw numbers.

  2013 MRE - Modular Operational Ration Enhancement (MORE) Hot Weather Pack #2 Review Caffeine Gum https://youtu.be/qxsveIugJvo
Here is the menu & caloric breakdown of the Hot Climate Menu #2 Contents:
First Strike bar (chocolate), Zapplesauce®, Energy gel (lemon lime), Smoked almonds, Caffeinated gum (peppermint), Carbohydrate electrolyte beverage (×2)
Nutrition Facts: 910 calories, 168 grams carbohydrates, 7 grams protein, 23 grams fat
The Modular Operational Ration Enhancement (MORE) was developed to augment daily operational rations with additional components tailored to particular environments. There are two types of MORE, one targets high altitude and cold weather while the other is intended for hot weather operations.
PURPOSE
Warfighters in extreme environments, such as cold weather, high altitude, or elevated temperature, require extra calories beyond the standard operational rations in order to combat weight loss and decreased physical and cognitive abilities. The MORE provides the correct amount of extra calories for these specific environmental scenarios with the right balance of fat, carbohydrate, and protein. By augmenting the MRE™ or FSR™ with additional calories and nutrients, the Warfighter is capable of performing at maximum capacity in extreme environments. The MORE is not a replacement to the MRE™ or FSR™; it is a scientifically balanced addition that ensures peak performance in even the most austere battlefield locations.
TECHNOLOGY
MORE components are calorically dense and carry a balance of carbohydrates, caffeine, electrolytes, vitamins, antioxidants, and amino acids. The MORE includes food components that are essential to improving the mental and physical abilities of Warfighters in demanding, extreme conditions.
CHARACTERISTICS The MORE-High Altitude/Cold Weather and MORE-Hot Weather are composed of developmental and commercial items, including caffeinated pudding, energy gels, carbohydrate-enhanced beverages, First Strike™ bars, carbohydrate-dense nut mixes, crackers, caffeinated gum and Zapplesauce®. Drink powders are issued in easy-to-use pouches hour-glass pouches. The MORE has a shelf life of 2 years at 80°F. All components are lightweight, low cube, can be eaten on the move without preparation, and are easy to consume and digest. The MORE is lightweight and compact, providing only the enhancements most critical to maintaining Warfighter mental awareness and physical stamina.

The First Strike Ration (FSR) is a compact, eat-on-the move ration concept from the United States Army, designed to be consumed during the first 72 hours of conflict, created by the United States Army Soldier Systems Center in Natick, Massachusetts. The Army said the FSR substantially reduces weight and load and is intended to enhance a consumer's physical performance, mental acuity, and mobility.

The FSR is a new assault ration developed to provide mobile soldiers with a variety of foods that are lightweight, calorically dense, familiar, and which are "easy to consume" than intermediate moisture foods.

* Enhanced mobility – components are described as "familiar, performance-enhancing, eat-out-of-hand" foods that require little or no preparation by the soldier. The beverages are reconstituted (CamelBak compatible) and consumed right out of the pouch. No water is needed for food preparation, only for the beverage mix. The food takes the form of pocket sandwiches to be eaten by hand.
* Lightweight – when compared to three Meals, Ready-to-Eat, the FSR reduces the weight and volume of one day’s subsistence by approximately 50%.
* Characteristics – has a minimum two year shelf life at 80 °F (27 °C) and provides an average of 2,900 calories per day. The FSR has nine meals per shipping container consisting of three each of three different menus.

- The new First Strike Ration includes items such as the First Strike! Bar, beef jerky, nut and fruit mix, caffeinated gum, applesauce, tortillas, honey BBQ beef pocket sandwiches and filled French toast pockets. The ration is meant to provide Soldiers with three meals a day, is about the size of a single MRE, and contains only items that can be easily eaten with the hands. It is designed for Soldiers on the move. (original caption)

The Soldier Fuel bar, formerly known as Hooah! bar, is a dairy-based calcium-enriched energy bar created by the United States military in 1996. It was originally provided to military personnel packaged within a field ration, such as the Meal, Ready-to-Eat, Meal Cold Weather, or First Strike Ration.

The name comes from the word "hooah", an expression of high morale, strength and confidence. Commonly used by American soldiers, Marines tend to prefer the word "Oohrah!" on the packaging. The bar originally had "HOOAH!" and the US Army seal on one side and "OOH-RAH!" and the US Marine Corps seal on the other; newer wrappers had both logos on the same side. The commercial version features the United States roundel instead.

The original military HOOAH! Bar came in apple-cinnamon, chocolate, raspberry, cran-raspberry, and peanut butter flavors. The smaller First Strike bars (provided in the concentrated First Strike Ration) come in the same flavors, except peanut butter; mocha is used instead. https://en.wikipedia.org/wiki/Soldier_Fuel

Pure caffeine powder can be purchased by anyone to boost the caffeine content of food or beverages. However, this product is not recommended. Just 1 teaspoon of caffeine powder has about 4706mg of caffeine, which is enough to cause serious harm and severe overdose symptoms. This product is the most dangerous caffeine related product!
The FDA recently posted a warning, urging consumers not to purchase this powdered caffeine. More recently, the FDA sent warning letters to 5 distributers of powdered caffeine.
The only people who should consider this product are those that have a digital scale and can precisely measure out a safe dose of caffeine.
Using common measuring devices like measuring spoons etc. will likely result in too large of a dose.
Some caffeine powders also use an "anti-caking agent" but this doesn't change the caffeine content enough to justify being more generous with this type.
We feel that unless you are a food or beverage manufacturer, buying bulk caffeine powder isn't a wise decision unless you buy the necessary equipment needed to measure it accurately.
Those in possession of caffeine powder should keep the product in its original packaging and out of the reach of children.
At least two deaths have been officially reported from overdosing on caffeine powder when accidentally ingested 2 spoonfuls. http://www.caffeineinformer.com/caffeine-content/caffeine-powder

You can eat, drink and chew caffeine but apparently you can also inhale caffeine through a vaporizer. Example: Rush caffeine infused vapor sticks.
A caffeine infused vape stick is essentially similar to an electronic cigarette, but contains no nicotine.

Instead, it has a small amount of caffeine suspended in a flavored liquid that is vaporized when inhaled.

RUSH Energy Vapor is a new product like this and I was recently sent a couple vapor sticks by the company to try out.

What’s RUSH Like?

Using a RUSH Energy Stick is similar to smoking, minus the smoke and the awful smell of course.

Sucking on the stick draws out an energy drink flavored vapor and exhaling releases this vapor, which has the appearance of smoke but isn’t.

The end of this caffeine infused vapor stick glows red, which is a bit strange since since this isn’t supposed to be referred to as an electronic cigarette, but in all accounts resembles one. http://www.caffeineinformer.com/caffeine-infused-vapor-stick-rush

Caffeine Amount of these Vape Sticks
Determining the caffeine dose from caffeine infused vapor sticks is a bit tricky for a couple reasons.
First, we know there is a very small amount of caffeine in the device. 11mg to be precise and there are about 600 puffs per energy vapor stick.
However, not much research has been conducted on this method of caffeine absorption. In theory, it is thought that it would take a very small amount of caffeine to have have an effect since it’s entering the blood through the lungs and mucus membranes.
Other Ingredients
Besides caffeine, RUSH Energy Vapor Sticks contain: Distilled Water, Propylene Glycol, Vegetable Glycerin, Flavoring.

Do Caffeine Infused Vape Sticks Work?
What’s really strange to me is despite my knowledge of how little caffeine RUSH actually contains, after a few puffs of the vapor stick, I do actually feel more awake.
Is it the caffeine or the placebo effect? Not sure, but RUSH does seem to work as intended.
It’s certainly not a caffeine rush like I’ve experienced with highly caffeinated products, but just more of an alertness.

Is Energy Vape Safe?
Here is the million dollar question. Caffeine wise, absolutely. It would take about 300+ RUSH Energy Vapor Sticks to put a person at the daily safe limit for caffeine consumption.
There is no risk of caffeine overdose from this product.
However, what we don’t know are the long-term effects vapor sticks may have on the lungs or health. Lungs were designed to inhale air, not: Propylene Glycol, Vegetable Glycerin, Rush Energy Vapor Flavoring, and Caffeine.
Furthermore, I can see caffeine infused vapor sticks as being appealing to kids and teens because they are a novel and interesting product to use.

Most people here might be equipped to measure caffeine powder properly.

1/10th grain scale for handloading is accurate to 0.00648 grams, precise enough for dosing caffeine safely. The user should still be careful, as one coffee cup's worth will weigh around 1.5 grains. Do NOT mix up grams and grains.

It's probably not a good idea to go referring to your handloading manual for caffeine dosage, unless you frequently handload .25 ACP.

Damn, now I want powder loads of popular calibers represented in cups of coffee.

The powder loads for the big black powder cartridges and shotgun shells were sometimes measured in drams.
In the avoirdupois system, the dram is the mass of  1⁄256 pound or  1⁄16 ounce. The dram weighs  875⁄32 grains, or exactly 1.7718451953125 grams. https://en.wikipedia.org/wiki/Dram_(unit)
- Bartram & Co 2.5 drams black powder flask

Dram is used informally to mean a small amount of spirituous liquor, especially Scotch whisky. The unit is referenced by the phrase dram shop, the US legal term for an establishment that serves alcoholic beverages.
- A 'wee dram' being added to flavour the haggis at a Burns Supper
I actually tried a haggis (friend's parents were on a traditional Scottish cuisine kick until they realized how horrible that stuff is) and you would need to pound down a whole bottle of Scotch to steady your nerves and kill the taste in your mouth in order to stomach this stuff. Chopped up sheep's lungs, heart, and kidneys mixed with oatmeal and probably road sweepings and stuffed into a sheep's stomach. Sounds great, right? But it turned out revolting. The US government actually forbids people selling food with lung tissue in it, but you can serve it for free at dinner. Problem is, you can't even give this stuff away in America.
Anyone else tried haggis? With or without a wee dram?

  How to Make Haggis https://youtu.be/MuEmB7frgTI
Today is Burns day, Scotland's national holiday celebrating the life of the poet Robert Burns. This holiday isn't just an excuse to get blasted. It's also a culinary tribute where revelers toast to the Scottish wordsmith over clinked glasses of Scotch whiskey while feasting on haggis—a savory pudding stuffed with oats, spices, and sheep's rumen, lungs, heart, and liver. Robert Burns was a huge fan of haggis, so much so that he even wrote a poem about it that mentions something about stabbing the innards with a knife as they get pulled out like the steaming entrails of a beast. Mmm.

We had no idea how to make haggis from scratch, so we called up our friends at the Nordic Food Lab, a non-profit culinary research institute based in Copenhagen, Denmark, to get the full monty. Ben Reade, a native Scotsman and the head of culinary research and development at the Nordic Food Lab, walked us through the labor of lamb love in the Nordic Food Lab's houseboat kitchen.

After oats, spices, four-day-smoked blueberries soaked in alcohol, a couple of hearts, and sheep's rumen, liver, lungs, diaphragms, kidneys, tongues, fat, and blood were mixed together and cooked, the warm pudding was ready for some culinary poetry. Ben brought it over to the Mad Symposium—an annual gathering where international chefs and culinary minds meet to eat, drink, and discuss topics in food—and shared it with the symposium's participants.

No haggis can be consumed without the help of a sharp knife and a healthy carbon dioxide-blowing bagpiper to appease the ghost of Burns himself. Or in the words of Ben Reade, "Who wants to eat French balls? This is how we want it in Scotland."

Cheers to you, Robert Burns.

Back to caffeine stuff.
Here's a package of Wired Waffles, containing 200mg of caffeine per serving.

I used to be big into supplements since I knew my regular diet was pretty lacking. You can usually find some amount of caffeine in multi-vitamins that have words such as "active" or "energy" on the label.

Caffeine is also common in a lot of "pre-workout" supplements.

From my experience Red Bull is probably my favorite for staying up days at a time on harmfully low amounts of sleep.

You might also pay attention to the Vitamin B# content of these, as this is also used to give short term energy. You'll typically find large amount of B vitamins in most energy boosters these days.

I've never used to supplements explicitly for their caffeine content. After noticing the huge amount of B vitamins, in the bottle I got from the gym. I'll try and post a pic later, but I think it had upwards of 1000% of the daily value of 6 and 12, maybe more. I will take half of one when if I feel like crashing. The result usually gets me through the 2nd half of my day, often along with more coffee.

I've heard lack of sleep is one of the most common problems in America, and I'm guessing, a lot of the modern world.

I actually use a lot of the MEG gum/pills, since coffee fucks my stomach.

If you want the best price/caffeine ratio, just get pills. But the gum is great to have for driving. I can get really tired fairly suddenly while driving. Not like a narcoleptic episode, but more like head nodding and starting to wander in my lane. The gum is a great way to instantly restore my ability to focus and get to where I'm going when the only other alternative would be to pull over somewhere and close my eyes for 30-45min. It's also great to have on hand for meetings and shit. Just be aware about dose, and how late you take it and all that. I suspect that caffeine effects people differently, as I could chew a piece right before bed and be fine, but some people it would destroy their night.

The MEG gum has fairly haphazard flavor quality control. So expect to get the occasional "cinna-mint" piece from them switching production using the same equipment or something.

>>17926
The Military Energy Gum (MEG) spearmint flavor tastes... REVOLTING! After a minute or so, the taste gets even worse. The cinnamon flavor is not so bad, but still horrible. This is gum; those cretins can make it taste great. Did they make it taste like garbage so people would not chew up a lot and overdose on caffeine? You really have to chew it with regular gum to make it palatable. Did I get bad batches?

Black-Black caffeine gum from Japan has a strong menthol and peppermint taste (but only 5 mg per piece). It taste like chewing an Altoids. It actually clears your sinuses! As I stated before, I used it and Xylish to stay awake in boring classes and in long road trips. Keep chewing a fresh stick or piece of gum every hour when the effects start to wane.

Another good tip for staying awake for long road trips is to listen to radio plays, like Dragnet (1949-1957 377 episodes), audio books, radio Shakespeare plays, or mystery dramas (but they have to be interesting to you to keep your attention). You have to pay attention to what is being said and described, but you are not visually distracted in doing this.

>>17927
Dunno. I always hate spearimint no matter what it is so I've never tried it. That said, the flavor quality control is hilariously bad with this gum. In addition to the flavor mixing I mentioned (which should only show up in 1-2 packs out of a box), the strength of the flavor can vary quite a lot.
I get the blue "normal mint" is basically mint+the bitterness from concentrated caffeine. I actually like the bitterness.

Funny you mention Black-Black, I actually ordered some a week ago and it's headed my way. It's my absolute favorite gum.

>>17927
The bitterness might be intentional as the bitter taste can be a bit of an eye opener for a lot of people. This is why my go to is Red Bull: it's got enough bitter to wake me up, without being terribly unpleasant.

Cold for easy. Methylphenidate for medium. Dextroamphetamine to make hard/grueling easy.
