Safety with THC concentrates

Concentrated THC Products (also known as hash oil, dabs, wax, earwax, honey, honey oil, resin, or shatter) are a product created by extracting THC from the Cannabis plant.

  • This product may contain up to 90 percent THC and is consumed by smoking, vaporizing, dabbing, or adding to food.
  • Consuming this highly concentrated form of THC increases the risk of an unpredictable high and negative physical and emotional reactions.
  • Since dabbing only recently became relatively common, there’s limited information on long-term health effects.
  • Using high THC products may cause psychosis — seeing or hearing things that aren't real.
  • Youth who use Cannabis with high THC concentrations are more likely to continue using Cannabis and to develop future mental health problems.
  • Making hash oil using flammable liquids is extremely dangerous and illegal. It has resulted in explosions, severe burns, and death. There are safer ways to make hash oil.
  • If you are of legal age and choose to use hash oil, we recommend buying it from a licensed Cannabis retail store.
