Does smoking marijuana affect how well birth control works?
Someone asked us:
Hi, does smoking marijuana affect birth control?
There’s absolutely no evidence showing that smoking weed affects birth control, including side effects and how well it prevents pregnancy. The only marijuana-related birth control problem you might have is forgetting to use your birth control correctly because you’re high. So just make sure you stay on top of your birth control, no matter what.
