A review involving 96 people in New Zealand, half of them controls and the other half regular cannabis users, found that smoking weed likely causes less alteration to human DNA than smoking tobacco.
Researchers looked at what effect heavy cannabis use — with and without tobacco — had on the DNA of participants, note study findings published this week in Translational Psychiatry.
Drug use is “known to make temporary or permanent alterations to a user’s DNA, by way of a process called DNA methylation,” according to Merry Jane. The study points out that “modifications, such as DNA methylation, contribute to complex traits and diseases,” including cancer and lupus. These alterations also make people “more likely to pass on birth defects to their children,” according to Merry Jane.
