Yes, there is a difference between CBD and hash oil. CBD, or cannabidiol, is a compound derived from the hemp plant and is often used for various purposes, including therapeutic benefits. CBD does not cause a 'high' and is different from hash oil, which is a concentrated form of THC derived from the cannabis plant. Hash oil typically has higher levels of THC and is used for its psychoactive effects. It is important to be aware of the differences and choose the appropriate product based on your needs and preferences.
