The dose, worked

4 tbsp infused olive oil × 9.87 mg per tbsp = 39.5 mg THC (theoretical) ÷ 8 portions = 4.93 mg per portion.

Theoretical maximum: it assumes complete decarboxylation (THCA × 0.877) and that every milligram ends up in the food. Real yield is usually lower, which is why you start with one portion and wait. Re-run the maths for your flower →

per portion
2.5510 mg
Start with one. Wait two hours.

Ingredients

  • 60 g basil leaves
  • 30 g pine nuts or sunflower seeds, toasted
  • 1 small garlic clove
  • 30 g Parmesan, finely grated
  • 4 tbsp infused olive oil
  • 4 tbsp plain extra-virgin olive oil
  • Juice of ½ lemon
  • Salt and pepper

Dosing notes

  • Stir into pasta off the heat. Boiling pesto degrades THC and makes the dose unpredictable.
  • One portion per person per meal; do not free-pour from the jar.

Why not all infused oil?

Eight tablespoons of infused oil would double every portion. Halving it keeps a first-timer's serving near 5 mg.

Educational content, not medical advice. Effects vary with body weight, tolerance and what else you have eaten. Label infused food with the milligrams per portion and the date, and keep it away from children and pets.
