THC stands for delta-9-tetrahydrocannabinol. It is a cannabinoid molecule in marijuana (cannabis) that’s recognized as the main psychoactive ingredient that causes people to feel high. THC content is expressed as mg/g or as a percentage of mg per gram. This is often referred to as "potency." THC is intoxicating and can produce a variety of intended effects, but consuming too much or choosing a product with a high potency potential can produce harmful or negative effects. We always recommend to starting at low potency’s to see how your body reacts.
