Cannabis Exposure Alters Genetic Profile of Sperm
THC exposure targets genes in two major cellular pathways and alters DNA methylation, a new study reports. Researchers say that wile cannabis triggers structural and regulatory changes in the DNA of users' sperm, they do not know yet whether the changes are passed down to the offspring and what effects that could have. ...
