The coffee cannabis connection
Coffee affects your metabolism in dozens of other ways besides waking you up, including your metabolism of neurotransmitters typically linked to cannabis, a study reports. The neurotransmitters related to the endocannabinoid system -- the same ones affected by cannabis -- decreased after drinking four to eight cups of coffee in a day. That's the opposite of what occurs after someone uses cannabis. The study also gives possible insight in the cause of munchies. Coffee may also increase the elimination of steroids. (2018-03-15)

Exposure to cannabis alters the genetic profile of sperm
New research from Duke Health suggests men in their child-bearing years should consider how THC could impact their sperm and possibly the children they conceive during periods when they've been using the drug. Much like previous research that has shown tobacco smoke, pesticides, flame retardants and even obesity can alter sperm, the Duke research shows THC also affects epigenetics, triggering structural and regulatory changes in the DNA of users' sperm. (2018-12-19)

Do we need to reform international drug treaties as more countries legalize cannabis?
The future of international drug control treaties is in doubt because of recent treaty-violating decisions to legalize cannabis use in Canada, the United States and Uruguay. Professor Wayne Hall, whose 2014 review of 20 years of cannabis research made world headlines, thinks so. If decriminalization is the way of the future, Hall advocates a cautious approach to policy reform that would involve trialing and evaluating the effects of incrementally more liberal drug policies.
