(From) Abstract: Recent European data facilitate an epidemiological investigation of the controversial cannabis–cancer relationship. Of particular concern were prior findings associating high-dose cannabis use with reproductive problems and potential genetic impacts… Cannabis is a more important carcinogen than tobacco and alcohol and fulfills epidemiological qualitative and quantitative criteria for causality for 25/41 cancers. Reproductive and transgenerational effects are prominent. These findings confirm the clinical and epidemiological salience of cannabis as a major multigenerational community carcinogen.

Young people who are exposed to adverse childhood experiences between the ages of 0 – 12 years, including parental drug misuse, are at highest risk for developing problematic adolescent cannabis use as teenagers, according to a new study.

Adverse childhood experiences (‘ACEs’) considered included physical, emotional and sexual abuse, emotional neglect, bullying, parental substance use, violence between parents, parental mental health challenges, and a parent being convicted of a criminal offence.

Risks for problematic adolescent cannabis use are highest for individuals reporting 4 or more ACEs, and were particularly raised for those with parental substance use or abuse
