CBD その他の植物性カンナビノイドは、がん細胞に対して次のような作用があることがわかっています：
- 細胞毒性（がん細胞を殺す）
- 抗増殖作用（腫瘍の成長を遅らせる）
- 抗転移作用（腫瘍の転移を遅らせる）
- 血管新生（がん細胞に栄養を運ぶ血管の形成）を遅らせる
- アポトーシス（がん細胞の自然死）とオートファジー（ 細胞の自食作用）
- がん幹細胞の増殖と転移を抑制する
- 抗がん剤に対する耐性形成の減少
- グリコシル化（タンパク質に糖類が付加する反応）の減少
- “bubbling cell death” などの新たに発見された作用
これまでの研究の多くは高 THC の医療大麻を使って行われてきましたが、近年の研究は、CBD に抗がん作用があることや CBD が標準的ながん治療の効果を高めることを明らかにしています。THC と CBD は一緒に用いると効果的であることが多く、その効果の一部は、がん細胞のミトコンドリア（細胞のエネルギーを産生する要素）に対する作用を介して発揮されます。研究からはまた、全草から抽出された成分に含まれるテルペンの一部に抗がん作用を持つものがあることも明らかになっています。またカンナビノイドは、微生物叢を介してがんの進行を遅らせます。疫学データの中には、大麻の使用が特定の種類のがんの発症リスクを高めることを示すものと、大麻の使用によってがんの罹患リスクが低減することを示すものが混在しています。
がんの標準治療と大麻を併用すると、疼痛緩和、食欲増進、生活の質の向上、認知機能、終末期の緩和ケアなどに役立ちます。またカンナビノイドを使うことで、オピオイド系の鎮痛薬の用量を減らすことができます。抗がん剤治療にあたっては、カンナビノイドが抗がん剤の神経毒性から脳細胞を保護しますし、内因性カンナビノイド様の化合物である PEA は心臓の細胞を護り、また CBD は放射線治療による潰瘍の生成を減少させます。カンナビノイドはまた、光線力学療法やオゾン療法といった治療の効果を高める可能性もあります。ただしカンナビノイドは、一部の抗がん剤の効果を妨げることもあれば、他の種類のがんでは抗がん剤に対する耐性を防ぐこともあります。中には、CBD の使用のみで腫瘍の縮小に著しい効果が見られる場合もあります。

がんのためにCBDを使っていると答えた人：214人
女性 51% | 男性 49%
回答者からは、32種類のがんの名前が挙がりました。一番多かったのは、乳がん、前立腺がん、大
腸・直腸がんでした。回答者の大部分は、手術、化学療法、放射線療法のいずれかを受けていました。
多くはがんが寛解した状態でした。多くの人は同時に CBD を、疼痛（44%）、睡眠障害（30%）、気
分障害（25%）のためにも使っていました。
がんのために CBD を使っている人は、ヘンプ由来の CBD だけを使っている人よりも、大麻由来の CBD を使用、あるいは大麻と併用している割合が高く（それぞれ 40% と 57%）つまり CBD と一緒に THC を摂っている可能性が高いと言えます。これは THC に鎮痛効果があるため、あるいは、THC と CBD にはいずれも抗腫瘍作用があるという基礎研究の結果がよく周知されているためかもしれません。

CBD によるがん治療の研究（がん全般）
- 2022: A systematic review of the effect of CBD on cancer cells
Biological Effects of Cannabidiol on Human Cancer Cells: Systematic Review of the Literature
“CBD inhibited cell viability and proliferation in most cellular districts except the integumentary apparatus. Also a significant inhibition of migration was observed in all cell types, while an increase in apoptosis at both high and low doses (greater and less than 10μM respectively). Considering inflammation, CBD caused an anti-inflammatory effect on nervous cells at low doses and on gastro-intestinal cells at high doses, while metastatic power was reduced even at low doses, but in a skeletal cell line there was an increased angiogenesis. CB1 receptor has been related to viability effects, CB2 to apoptosis and TRPV1 to inflammation and invasiveness.” - 2022: A review of CBD in cancer treatment: not just for symptom control, but for anticancer action itself

The non-psychoactive cannabidiol triggers caspase activation and oxidative stress in human glioma cells
“Massi et al. observed that CBD had anti-proliferative effects in human glioma cells by producing ROS and depleting GSH stocks. However, in non-transformed glial cells, the drug did not induce oxidative stress. Other cannabinoids such as anandamide behave in the same way. Thus, the antioxidant or pro-oxidant properties of cannabinoids seem to depend on biochemical and cellular features of tumor versus non-tumor cells, such as differences in signal transduction and/or redox state.” (quote from this 2019 review)
