Cancer screening is not available for many types of cancers. Even when tests are available, they may not be recommended for everyone. Universal screening or mass screening involves screening everyone.[129] Selective screening identifies people who are at higher risk, such as people with a family history.[129] Several factors are considered to determine whether the benefits of screening outweigh the risks and the costs of screening.[128] These factors include:

Right from the start, the Feds understood that resin content is the key factor that distinguishes marijuana from industrial hemp. Today, however, federal law includes a recently added caveat that officially characterizes industrial hemp as having no more than 0.3 percent THC by dry weight. Products containing such a tiny amount of THC should not have an intoxicating  effect.
CBD, short for cannabidiol, is the main non-psychoactive compound found in marijuana and hemp. It does not interact with the body the same way as THC and cannot get you high. At the same time, CBD has many of the plant’s most significant medical and medicinal benefits. CBD can reduce seizures in epilepsy patients and a growing body of research finds it useful for reducing pain, acne, anxiety, inflammation and more.
