THC oil is a concentrated form of tetrahydrocannabinol, the main psychoactive compound found in the cannabis plant. It is typically extracted from the plant's flowers and leaves, resulting in a potent oil that can be used for various purposes, including medicinal and recreational use. THC oil can be consumed in different ways, such as through vaping, edibles, or sublingual drops. The effects of THC oil can vary depending on the dosage and individual tolerance. Users often report feelings of euphoria, relaxation, and altered perception. However, it can also cause side effects like anxiety or dizziness, especially in higher doses. As with any cannabis product, it's important to use THC oil responsibly and be aware of local laws regarding its use.
