Concentrates are highly-potent forms of cannabis that come in a variety of styles. Because concentrates are so strong, it is important to consume them with caution.

  • Kief
    Also referred to as dry sift or pollen, kief consists of the tiny, crystal-like growths covering cannabis flower.
  • Hash
    Also known as hashish, hash is made from the resin of cannabis plants. Its consistency is usually dry, crumbly, and brick-like.
  • Butane hash oil (BHO)
    This concentrate is produced by using butane to extract cannabinoids – chemical compounds like tetrahydrocannabinol (THC) and cannabidiol (CBD) – from cannabis plants. The consistency of BHO products can vary from a glasslike “shatter” to a soft wax.
  • CO2 oil
    A relatively new concentrate on the market, CO2 oil is produced by an extraction method that uses pressure and carbon dioxide to pull cannabinoids – chemical compounds like tetrahydrocannabinol (THC) and cannabidiol (CBD) – from cannabis plants. CO2 oil is usually consumed through portable vaporizer pens.

Edibles include products such as cookies, sodas, brownies, candies, and beverages that contain cannabis. It may take roughly one to four hours to feel the effects of an edible after consuming it, and those effects may last longer than expected. How they impact you depends on your metabolism, the amount you eat, and medications or alcohol used at the same time. The amount of cannabis in edibles also can differ product to product — for example, one cookie or brownie may contain multiple servings, so be sure to check the packaging for dosage information before consuming.

Compared to smoking or vaporizing, eating or drinking cannabis products may have delayed effects. As a rule of thumb, start low, go slow, and make sure you wait until you feel the full effects of the product before you have more.

Since marijuana-infused edibles look like regular food, it is especially important to keep them stored securely, locked and away from children and pets. If your child ingests cannabis, call the poison control hotline at (800) 222-1222, or dial 9-1-1 if the reaction seems serious. If you are worried about your pet, call your vet.

Topicals include marijuana-infused lotions, balms, oils, and other transdermal products that are absorbed through the skin. Some people may find that they help relieve pain and calm inflammation, though more scientific research is needed. Topical products may not be psychoactive, meaning they do not get consumers “high.” However, transdermal patches (which deliver cannabis to the bloodstream) containing high tetrahydrocannabinol (THC) content may cause mind-altering effects.
