Are Full Spectrum CBD Oils More Likely to Cause Side Effects?
Full spectrum CBD oils contain a wider range of cannabinoids and terpenes from the hemp plant, including trace amounts of THC within compliant limits.
Some individuals may be more sensitive to these compounds, particularly THC, which may influence how the product feels or how side effects are experienced.
This does not necessarily mean full spectrum CBD oils are harmful, but product transparency and proper testing are important when choosing CBD products.
