There are two main types of cannabis: sativa and indica. They have distinctive differences in their effects.


  • Sativas generally produce more energetic, uplifting, and cerebral effects.

  • They are a good choice if you need to medicate during the day and stay alert.

  • They provide pain relieving effects without making you tired.

  • For some people however, they can produce anxiety and may not be an effective treatment for those patients.




  • Indicas generally produce more sedating, calming, and bodily relaxation effects.

  • They are a good choice for those with strong chronic pain and insomnia.

  • The pain relieving properties are felt more directly in the body.

  • For some patients, Indicas can make them feel lazy and would not be recommended for day time use.


  • Hybrids are cannabis plants that have been cross bred with various combinations of indica, sativa, or other types of cannabis.

  • You could have an even 50% sativa/50% indica hybrid, or you could have plants that are sativa dominant or indica dominant. These hybrids combine effects between the two varieties.

  • For example, a sativa dominant hybrid might be uplifting and give a patient good focus, but still retain strong body relaxation effects like an indica.

  • Almost all common varieties of cannabis are a hybrid of some sort.

  • Especially difficult to find are pure sativas, as most of them have been hybridized to grow more easily indoors.

  • Sativas can reach 12 ft in height or more when grown outdoors.



THC (Tetrahydrocannabinol), CBD (Cannabidiol), and the Cannabinoid Family.

THC (Tetrahydrocannabinol)

THC is the main psychoactive compound found in cannabis. Almost all cannabis is dominated by this compound. THC has mild to moderate analgesic effects. Other effects include relaxation, alteration of visual, auditory, and olfactory senses, fatigue, and appetite stimulation. THC has marked anti-emetic (anti-nausea and vomiting) properties as well as mild antioxidant activity sufficient to protect neurons against oxidative stress.

CBD (Cannabidiol)

CBD is usually the second most common compound found in cannabis. This compound was discovered more recently than THC and shows great therapeutic promise. It has displayed a sedative effects in some animal tests and also conversely, other studies indicate that CBD can increase alertness. It has been shown to relieve convulsion, inflammation, anxiety, and nausea, as well as inhibit cancer cell growth. Recent studies have shown CBD to be as effective as atypical anti-psychotics in treating schizophrenia. Studies have also shown that it may relieve symptoms of dystonia. CBD has no psychoactive effect. In fact, it reduces the ‘high’ associated with the more common type of THC saturated cannabis. Medicine that is high in CBD, and low in THC is ideal for patients that are looking for therapeutic effects with little to no psychoactive properties!

Cannabinoid Family

There are at least 85 other types of cannabinoids. They each have a variety of effects that should be studied as they possibly offer different therapeutic effects. The illegality of the plant has made medical research very difficult for scientists and doctors, and the majority of studies that have been performed only test THC and CBD. We hope that science overcomes political obstacles when it comes to medical cannabis research and we will gain a better understanding of how cannabis works as medicine.
