In the past two decades, the number of brain tumors has increased by up to 40% in the U.S. and Europe, particularly among men between ages of 20 and 40<ref>http://www.healthandenvironment.org/brain_cancer/peer_reviewed</ref> — the same demographic that is most likely to have smoked pot. However, conclusions based on a review of published biomedical research found that cannabinoid compounds unique to cannabis actually exhibit promising anticancer properties, reducing both tumor size and cancer pain.<ref>{{Cite journal|last=Nikan|first=Marjan|last2=Nabavi|first2=Seyed Mohammad|last3=Manayi|first3=Azadeh|date=2016-02-01|title=Ligands for cannabinoid receptors, promising anticancer agents|url=https://www.ncbi.nlm.nih.gov/pubmed/26764235|journal=Life Sciences|volume=146|pages=124–130|doi=10.1016/j.lfs.2015.12.053|issn=1879-0631|pmid=26764235}}</ref>
