Toxicity Level	2
Toxicity Explanation	The toxicity level of CBD (Cannabidiol) is relatively low. It's been reported to be generally well-tolerated, especially at doses used for epilepsy. Typically, side effects may include tiredness, diarrhea, and changes in appetite or weight. However, as it is currently under investigational use in cancer treatment, including glioblastoma, the potential toxicities specific to cancer patients, particularly those with glioblastoma, are not fully understood and are currently under active research. It's essential to discuss with your healthcare provider before starting any new treatment regimen.

Notes: CBD, a non-psychoactive component of cannabis, has been explored for its potential therapeutic effects in cancer treatment, including anti-inflammatory, analgesic, and anti-nausea properties, as well as possible direct anti-tumor effects. While preclinical studies have shown promising results, including inhibition of tumor growth and synergistic effects with chemotherapy in models of glioblastoma and other cancers, conclusive evidence from clinical trials is needed to fully understand its efficacy and optimal use in cancer treatment.

Recent research into the use of CBD (cannabidiol) for treating glioblastoma in human clinical trials has shown promising results, particularly in its potential impact on overall survival (OS). One study involved a Phase II trial with Sativex, an oral spray containing both CBD and THC, in combination with chemotherapy for patients with recurrent glioblastoma. The earlier Phase I trial suggested that this combination might extend survival, leading to the larger Phase II trial. This ongoing trial aims to provide more definitive evidence on whether the addition of Sativex can significantly improve overall survival rates.

Another trial involved Nabiximols (formerly known as Nabisol), another cannabis-based drug. This trial focused on patients with glioblastoma and investigated the potential benefits of adding Nabiximols to the standard treatment regimen. Preliminary results indicated that some patients experienced an increase in overall survival, although further research is needed to confirm these findings.
