Finding your most effective CBD to THC ratio will aid in maximizing the potential medicinal benefits cannabis can provide.  Whether you’re an experienced cannabis user or embarking on a new treatment regimen that involves cannabis, a fundamental understanding of how to find your ideal ratio can help you achieve your desired results.

What is a CBD:THC ratio?

This refers to the amount of CBD and THC that is contained in any form of cannabis, including smokable flower, edibles, cartridges, tinctures, sublingual sprays, creams/salves, tablets, capsules and concentrates. The optimal CBD:THC ratio will vary depending on one’s individual physiology, medical conditions, and cannabis tolerance.  

How to find your ideal ratio.

THC dominant options (0:1) will provide varying degrees of psychoactivity.  THC also induces appetite, reduces inflammation, and can provide relaxing and/or cerebral effects.  Adverse effects may include tachycardia, anxiety, and paranoia. These can be reduced by introducing CBD into the equation.

A 1:3 ratio of CBD to THC results in a some psychoactivity while minimizing THC’s unwanted side effects, producing a calming sensation with reduced anxiety, stress relief and exhibiting anti-inflammatory properties.  This ratio can act an as advanced pain reliever with the synergistic benefits CBD and THC provide.

A ratio of equal parts CBD to THC (1:1) is considered highly effective for pain relief, anxiety, spasticity, fibromyalgia, insomnia, nausea and appetite stimulation. This ratio shows promise in relieving symptoms associated with Multiple Sclerosis and may be able to kill certain cancer cells and inhibit tumor growth.  A 1:1 can be a good starting point for many due to the multitude of conditions it may treat with minimal impairment.

Higher CBD options, such as 2:1 or 3:1, may be an ideal ratio for combating autoimmune disorders, gastrointestinal issues such as Crohn’s and colitis, arthritis, and psoriasis with little to no psychoactivity.  

CBD dominant ratios of 25:1 or 1:0 (hemp based CBD) offer no psychoactivity and may be most effective for curbing high anxiety, depression, seizures, psychosis, PTSD, and neurodegenerative conditions such as Parkinson’s and Huntington’s Disease.  

As with any treatment program, start small and work your way up incrementally.  Tapering up to the proper dosage is typical when one begins a new medication and medicating with cannabis is no different.  Cannabis is a very individualized medicine, so feel free to ask as many questions as you have from one of our knowledgeable Patient Consultants.  It’s strongly advised to consult with your primary care physician or specialist before starting any medical marijuana regimen.

The Research.

People who live with neurodegenerative disorders such as Multiple Sclerosis (MS) may be able to benefit from the advanced anti-inflammatory properties exhibited by both THC and CBD.  The Journal of Neuroimmune Pharmacology published an Israeli study in December 2013 focused on MS utilizing a 1:1 ratio with promising results.

Higher THC doses are thought to possibly be key in the treatment of fighting cancer cells and inhibiting tumor growth. CBD has demonstrated promise in inhibiting angiogenesis.  When taken together, a study supported the efficacy of a 1:1 treatment regimen for severe cancer related pain.

CBD’s strong anticonvulsant properties have shown promise in controlling seizures, allowing for CBD dominant ratios of 25:1 or even higher to work effectively, particularly in children.  However, it is suggested that other cannabinoids are key in maximizing the treatment of seizure related conditions.

CBD dominant options may also be effective for treating mood altering conditions such as schizophrenia due to its antipsychotic effects.  A German study published in March 2012 explored this in a double blinded clinical trial.

A study from October 2016 suggests cannabis may be able to assist with the symptoms associated PTSD.  PTSD is a very individualized condition, necessitating more studies but higher CBD strains may be a good option for reducing anxiety and stress.
