What is THC?
THC is one of the active substances in weed. It's the abbreviation of Δ9-Tetrahydrocannabinol - the cannabinoid making you high or stoned. High is a more mental effect, while stoned is a physical feeling. Depending on the strain, you feel more high or stoned.
The effect of THC works because THC mimics a body's own substance. That substance fits like a key in a lock, called the cannabinoid receptor. We have receptors throughout our body able to receive THC and other cannabinoids. For this reason, we can feel it in our bodies and in our heads. A high THC percentage in marijuana creates a tingling sensation in your head. Sometimes it stimulates the imagination, creativity or sexual excitement. If you combine it with other substances like CBD and terpenes, THC can give a heavy feeling in your arms or legs. The effect can differ per type of marijuana. Generally, we distinguish three types of weed, in which each strain can be divided.
