The risks of using cannabis products containing THC (the chemical that gets you high) are not currently clear. That’s why clinical trials are needed before they can be used.
Generally, the more THC the product contains, the greater these risks are.
But in reality, most products will contain a certain amount of THC.
What about products available to buy?
It’s likely most of these products – even those called “CBD oils” – will be illegal to possess or supply. There’s a good chance they will contain THC, and may not be safe to use.
The specialist will discuss with you all the other treatment options first, before considering a cannabis-based product.
And it is only likely to be prescribed for a small number of patients.
Health stores sell certain types of “pure CBD”. However, there’s no guarantee these products will be of good quality.
As CBD grows in popularity, so does the research on it but there are currently few clinical studies on the effects of CBD oil. As such, some of these claims are better supported by studies than others.
CBD oil comes as full-spectrum oils or in forms that contain CBD isolates. Unlike isolates, which contain CBD only, full-spectrum oils contain a variety of compounds found naturally in the cannabis plant, including proteins, flavonoids, terpenes, and chlorophyll. Alternative practitioners believe these compounds offer more substantial health benefits, although there is no clear evidence of this.
Medical marijuana is frequently prescribed to people with intractable (treatment-resistant) pain, including those with terminal cancer. There is some evidence that CBD contributes to this benefit.
CBD is the short name for cannabidiol, one of the two chemicals—among the dozens in cannabis—that have the most health benefits. The other, tetrahydrocannabinol (THC), produces the psychoactive effects described as being “high.” CBD oil generally does not contain THC, although some trace amounts may be present in products sold in certain states.
Clinical research has shown that CBD oil can trigger side effects. Severity and type can vary from one person to the next.
