Scientists say marijuana alters DNA of sperm and 'may pose a risk' to smokers' fertility or even their future children
The study found that the drug alters the DNA of the sperm of the smoker and might affect his ability to conceive a child.
Scientists warn that men who are planning to have children with their partners must stop smoking marijuana at least six months before attempting to conceive the child. A study conducted at Duke University and published in the journal Epigenetics (a monthly peer-reviewed scientific journal covering research pertaining to epigenetics) shows that the drug alters the DNA of the sperm of the smoker. The Daily Mail reports that the study, led by Dr. Susan Murphy, was the first of its kind and used samples obtained from healthy men aged between 18 and 40 who admitted to smoking cannabis at least once a week for the past six months.
