Is medical cannabis safe and effective?

Is medical cannabis safe?
The most common uses of medical cannabis are pain management, body and mind relaxation and insomnia. Strains with a big CBD percentage or high on terpenes like linalool can do wonders in case of anxiety, nausea or inflammation.

While cannabis-based medicines are based on only two cannabinoids -THC and CBD- your home-grown medical cannabis has all the cannabinoids and terpenes of the plant. These work together in complete synergy to give you the best results.
In this article we will explore the effectiveness and safety of medical cannabis.
Medical cannabis effectiveness on cancer patients
Health practitioners in some countries prescribe cannabis for cancer patients. Amongst the benefits of medical cannabis, they highlight the treatment of:
- Nausea and vomiting related to chemotherapy
- Loss of appetite and loss of body weight in cancer patients
- Severe-refractory cancer-pain

There are +450 chemical compounds in cannabis plants. Amongst these, at least 113 are cannabinoids and over a 100 are terpenes. However, pharmaceuticals only count on two compounds: THC and CBD. Three cannabis-based medicines have been approved in several countries:
Dronabinol (MarinolⓇ) and Nabilone (CesametⓇ): based on synthetic cannabinoids. Used to prevent or reduce chemotherapy-induced nausea in cancer patients. In the US the FDA (Food and Drug Administration) has recently approved them both.
Nabiximols (SativexⓇ): developed as a treatment for multiple sclerosis but also used as a pain-reliever in cancer pain. Formulated from cannabis extracts. This oral spray has been in use for years in 21 countries.
Medical cannabis strains
Here is a quick description of the effects and possible therapeutic uses of the three types of cannabis varieties:
Sativa
The “head high” one, uplifting, stimulating. Medicinal Sativa strains are recommended to beat depressive states, for pain relief, muscle relaxation, to treat insomnia and to stimulate appetite. Our best Sativa-dominant medical cannabis strains are:
- CBD 1:1 Silver Lame Haze Auto (1:1 CBD:THC ratio, less psychoactive but strong body stone)
- Golden Lemon Haze Fem (High on THC, long-lasting effects, pain-relieving)
Indica
The relaxing one, with strong body effects. Your night time buddy. Its CBD ratio can be higher. CBD does not produce a high. Indica strains are also recommended for pain relief, muscle relaxation and insomnia. However, these babies come with an extra bonus: an anti-epileptic effect and an anti-anxiety one. Our best Indica-dominant medical strains are:
- CBG Zerodue Fem (up to 15% CBG, 0,1% THC. Anti-inflammatory, appetite inducing, anti-depressive. Not psychoactive)
- CBD Critical XXL Fem (10% CBD, 0,5% or lower THC. Winner of the medicinal category at the 2021 Highlife Cup. Very aromatic strain, not psychoactive, relaxing)
- Girl Scout Cookies Fem (High on THC. Anti-nausea, appetite stimulation. Happy high!)
- O.G. Kush Fem (Extremely high on THC, pain-relieving)
- Northern Lights Fem (Strong body stone, anti-anxiety, happy and long-lasting high). More info about Northern Lights Autoflower.
- Candy Dawg Auto (Very high on THC, best for relaxing)
- Sherbet Fem (High on THC, good against stress)
Hybrid
This is the blend of the two mentioned above. Hybrids are Indica-dominant or Sativa-dominant, so you get an idea of what to expect from them.

Medical cannabis side effects
More research on the actual amount and properties of the components of marijuana must be done in order to determine its long term side effects. These could vary depending on the way of consumption (smoking, vaping, edibles, etc) or on individuals (age, weight, tolerance, etc). Short-term known side effects can be:
- Impaired memory
- Difficulty with thinking and problem-solving
- Reduced coordination
- Dry mouth
- Altered sense of time
- Mood swings
- Altered senses
- Anxiety
- Dizziness
- Fatigue

NOTE: CBD-rich strains have proven to have less side effects than THC-rich ones.

As for its effects on animals, there are already CBD for pets are products available for them but there is no consensus amongst vets. More study needs to be done on our pets’ endocannabinoid system.
Why should medical cannabis be legalized?
The legalization of medical cannabis in several countries has led to more scientific research about both its therapeutic benefits and its potential side effects. Countries like the US, Canada, Uruguay, Luxembourg, Mexico or Morocco contribute to expanding the current limited research being done on medical cannabis.
Is medical cannabis legal? Unfortunately not everywhere, but it is steadily gaining space.
Legalization facts: In December of 2020, the UN voted to recognise the potential medical value of cannabis. There are 43 countries where medical cannabis is legalized. What states in the US allow medical cannabis? There are currently 36 and four territories.
