Cannabis plants contain more than 60 unique compounds called cannabinoids. Two of the most common compounds are tetrahydrocannabinol (THC) - the psychoactive chemical that produces the cannabis high - and cannabidiol (CBD). Marijuana plants contain high levels of THC, classed as illegal in many countries and states, and hemp contains very little. While hemp contains higher levels of legal CDB. Hemp is legally refined in industrial factories for products such as hemp seed foods, hemp oil, wax, resin, rope, cloth,  paper, and fuel. As a result, its production and sale is legal in many countries and states including the UK. Hemp naturally contains compounds which affect the endocannabinoid system, an internal pathway found in mammals. Nearly every tissue contains receptors which respond to the components found in cannabis. Once triggered, these receptors activate a chemical reactions aimed at supporting the body's natural stress response mechanisms. Marijuana plants and leaves contain high levels of THC, classed as illegal in many countries and states, and hemp contains very little. While hemp contains higher levels of legal CDB.

Canna Companion, based in Sultan in Washington, uses hemp from the Cannabis sativa strain in its capsules and biscuits for both cats and dogs. It is run by vets Dr Greg Copas and Dr Sarah Brandon. 'The phytocannabinoid and terpenoid profiles work perfectly for pets,' explained the firm. 'Due in part to their small body size, dogs and cats can take advantage of small amounts of CBD, THC and other cannabinoids found in hemp and can therefore reap the benefits of this great plant.' 'We are not interested in, nor are we advocating the administration of, the well-known psychotropic compound THC, in concentrations sufficient to produce the 'high' or psychotropic effects which are normally associated with marijuana.

'It works best when admininstered under the direction of a veterinarian as part of a total health care regimen.' It advises pet owners never change prescribed medication doses or frequency of administration without advice from a vet.
