Creating homemade lye soap is a truly rewarding experience, as it allows for a personalized touch to the recipe. However, it is important to note that working with lye can be dangerous if not handled properly. This recipe is not recommended for beginners, but for those with experience in soap making, it offers a unique opportunity to incorporate cannabis oil. Before starting, ensure you have heat resistant gloves and safety goggles for your protection throughout the process.


  • 1 cup cannabis-infused oil
  • 8 ounces lye
  • 20 ounces water
  • Optional: Essential oils for fragrance (e.g., lavender, eucalyptus, or citrus)

Going Step by Step

  1. Safety first: Put on your heat resistant gloves and safety goggles.
  2. In a well-ventilated area, carefully add the lye to the water, stirring gently until dissolved. Be cautious as the mixture will become hot and release fumes.
  3. Allow the lye mixture to cool down to around 100°F (38°C).
  4. Gently heat the cannabis oil in a separate container until it reaches the same temperature as the lye mixture.

  6. Add any optional essential oils for fragrance, stirring gently to incorporate.
  7. Pour the soap mixture into molds of your choice. Silicone molds or lined wooden molds are popular options.
  8. Allow the soap to cool and harden for 24-48 hours.
