Bulletproof Cannabis Coffee, Dosed Your Way

A five-minute butter coffee where only part of the fat is infused, so you learn your dose before you scale up.

By the High Society team3 min read

Cannabis coffee in the bulletproof style is hot coffee blended with butter or ghee and coconut oil until creamy and foamy. THC dissolves in fat, so a measured spoon of canna-coconut oil or infused ghee blends right in, while the rest of the fat stays plain to keep the dose small.

Dosing and safety: start small, plan a slow day

If your canna-coconut oil works out to about 13 mg per teaspoon at most, a quarter teaspoon carries about 3 mg and an eighth about 1.6 mg. Infused food can take as long as 2 hours to register, and its effects can linger 4 to 12 hours, so a morning cup shapes your whole day. Make it a day-off drink, never one before work or driving. Our THC dosage guide walks through first doses.

What goes in cannabis coffee

Most of the fat is plain: a tablespoon of unsalted butter or ghee and a teaspoon or two of coconut or MCT oil. The infused part is just 1/8 to 1/4 teaspoon of canna-coconut oil or infused ghee, from our cannabutter recipe or canna oil recipe. Measure it with a real measuring spoon, and add a pinch of salt.

How to blend hot coffee safely

Warm the blender jar with hot tap water first. Fill it no more than halfway, since steam can push hot liquid past the lid, and vent the lid the way your blender's manual says for hot liquids. Hold a folded towel over the lid, start on the lowest speed, then raise it and blend for about 20 seconds, until foamy. A milk frother in a tall mug works too.

Storage and labeling

Drink it right away, before it separates and before anyone else can grab an infused cup. Keep the infused oil labeled with its strength and date, apart from the plain oil and out of children's and pets' reach. Homemade oils made with herbs belong in the fridge for no more than 4 days, so freeze small portions of what you won't use by then.

Variations

  • Dairy-free: plain coconut oil in place of the butter, with canna-coconut oil rather than infused ghee.
  • Iced: blend with room-temperature coffee, then pour over ice.
  • Spiced: a pinch of cinnamon and a drop of vanilla.
  • Sweet: maple syrup, or canna-honey with all-plain oils.

Frequently asked questions

How much canna-oil should go in coffee?

An eighth to a quarter teaspoon. With oil at about 13 mg per teaspoon at most, a quarter teaspoon is roughly 3 mg. Canada's chief medical officers of health set 2.5 mg as a sensible ceiling for a first edible, so an eighth is the cautious start.

Does caffeine change how THC feels?

Not much, according to the first controlled human study of the pair. In a 2025 Johns Hopkins trial with 20 adults, adding about 180 mg of caffeine to 7.5 mg of oral THC barely changed THC's effects, impairment or blood levels. It may have shifted how impaired people felt behind the wheel, and it won't cancel out THC.

Can I use cannabutter instead of coconut oil?

Yes. Butter coffee already calls for butter, so swapping part of it for cannabutter or infused ghee works the same way. Measure the infused portion by the teaspoon and keep the rest of the fat plain, so the dose stays small.
